The inventor of the present application has found through research that: in the current implementation scheme for managing the power quality in the transformer area, a dedicated controller is generally required to be configured for each type of power quality management equipment in the transformer area, so that the complexity of an equipment system in the transformer area is high, the equipment investment cost is high to a certain extent, specific power quality problems are often sensed and managed, the relevance analysis of the power quality problems is insufficient, the function is single, and the global sensing of the power quality problems in the transformer area is lacked.

or, in the multiple transformer areas, the edge internet of things agent device in each transformer area obtains the power quality data of each transformer area through the power quality monitoring device in each transformer area, and sends the target data in the power quality data of each transformer area to the cloud device, and then can receive a second power quality control instruction corresponding to the target data of the multiple transformer areas generated by the cloud device based on a second power quality control rule of the cloud device, so that the second power quality control instruction sent by the cloud device is transmitted to the corresponding power quality control device in each transformer area through the edge internet of things agent device in each transformer area, so that the power quality control device executes the second power quality control instruction, and thus the control of the power quality in each transformer area is realized based on the power quality data in the multiple transformer areas.
Therefore, the control of the power quality treatment equipment in each distribution area can be achieved through the edge internet of things agent equipment and/or the cloud equipment in the distribution area, so that the power quality treatment in each distribution area is achieved, a special controller does not need to be set for various power quality treatment equipment in the distribution area, and the complexity of a distribution area equipment system can be reduced.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Referring to fig. 1, a flowchart is shown for implementing a method for governing power quality of a distribution room, which may be applied to an edge agent device in a first distribution room, where the first distribution room refers to any one distribution room in a whole power grid, and not only to a specific distribution room. The method in the embodiment is suitable for the edge Internet of things agent equipment in any distribution area in the whole power grid. The first power quality control rule can represent a control scheme which can be carried out by the power quality control equipment when the power quality control instruction is executed, for example, different power quality control instructions are executed for different power quality data, so that different power quality control effects are realized. The technical scheme in the application is mainly used for controlling the power quality in the distribution network area under the condition that the complexity of a power grid equipment system is not increased.
Specifically, the method in this embodiment may include the following steps:
step 101: and acquiring at least one item of power quality data of the first transformer area by using the power quality monitoring equipment in the first transformer area.
The power quality monitoring device refers to a device for measuring and analyzing the quality of alternating current power supplied to a power receiving section of a user by a public power grid, and can also be called as a power quality sensing device, and includes but is not limited to intelligent primary devices, intelligent secondary devices and the like in a transformer area.
As shown in fig. 2, the entire power distribution network is divided into a plurality of distribution areas, each distribution area is configured with an edge internet of things agent device, at least one power quality monitoring device and at least one power quality management device, the edge internet of things agent device may also be referred to as an edge device, the power quality monitoring device and the power quality management device may be referred to as an end device, and data connection is established between each edge internet of things agent device in the power distribution network and the cloud device. The edge internet of things agent device may be a device deployed at a distribution transformer gateway of the affiliated distribution area, including but not limited to an intelligent distribution transformer terminal or an intelligent distribution area terminal of the distribution area. The edge internet of things agent equipment in each platform area has edge computing capacity, supports a software definition function, and can realize data interaction and corresponding data processing between cloud equipment and the edge internet of things agent equipment and between the edge internet of things agent equipment and end equipment such as power quality monitoring equipment and power quality management equipment.
It should be noted that, unlike the existing controller configured specifically for each power quality management device, the edge internet of things proxy device in this embodiment may be an edge device in the distribution room that can simultaneously implement other functions. That is to say, the power quality management function of the distribution room in this embodiment shares the edge internet of things agent device in the distribution room with other functions. For example, the edge internet of things agent device in this embodiment may be an edge internet of things agent device that has been configured in the platform area and is implementing functions of collecting electric meter data, and the like, or the edge internet of things agent device in this embodiment may be an edge internet of things agent device that is to be configured in the platform area and is capable of implementing functions of charging electric vehicles, and the like at the same time.
In specific implementation, in this embodiment, the power quality monitoring device and the power quality management device may be deployed as needed at a key node in the platform area, where the deployment as needed may be understood as deploying the power quality monitoring device and the power quality management device according to a requirement of power quality management performed by the platform area, for example, the first platform area may only need to perform three-phase unbalanced power quality management, or the first platform area may not only need to perform three-phase unbalanced power quality management but also need to manage harmonics, and the like. The power quality monitoring device in this embodiment can be used to obtain power quality information of the distribution transformer gateway, each line branch, the distributed energy, the charging pile, the user and the like according to different devices, and provide a data base for monitoring and controlling the power quality of the distribution transformer.
It should be noted that the power quality data may include, but is not limited to, voltage, current, frequency, harmonics, ripple, flicker, power, etc., and may be indicative of the power state in the station area. Based on the above, the monitoring of the power quality in the distribution area can be realized on the edge internet of things agent equipment in the distribution area based on the power quality data.
The data transmission is carried out among the edge Internet of things agent equipment, the electric energy quality monitoring equipment and the electric energy quality treatment equipment which belong to the same transformer area through a first communication network, and the data transmission is carried out among the cloud equipment and the edge Internet of things agent equipment in each transformer area through a second communication network.
Specifically, the first communication network may be a local communication network in the distribution room, and the local communication network may be used for communication between the power quality monitoring device and the edge internet of things proxy device, and between the edge internet of things proxy device and the power quality management device, and the communication modes include, but are not limited to, serial communication, wireless communication, optical fiber communication, power line carrier communication, and the like;
the second communication network may specifically be a telecommunication network, and the telecommunication network may be deployed between a distribution area and a cloud device of the distribution network, and is used for communication between the edge internet of things agent device of the distribution area and the cloud device, and the communication mode includes, but is not limited to, wireless communication, optical fiber communication, satellite communication, and the like.
Based on this, in this embodiment, the edge internet of things agent device of the first platform area may receive, through the local communication network, at least one item of power quality data of the first platform area, which is collected by one or more power quality monitoring devices. For example, the intelligent primary equipment in the transformer area is used for acquiring the voltage, current, frequency, harmonic, fluctuation, power and other information of the transformer area distribution gateway.
Step 102: and generating at least one power quality control instruction corresponding to the power quality data based on the first power quality control rule.
The first power quality control rule refers to a first power quality control rule which is pre-configured in the edge internet of things agent device and can represent a power quality control mode.
Specifically, in this embodiment, the edge internet of things proxy device may process power quality data such as voltage, harmonic, flicker, and the like received through the local communication network based on a first power quality control rule configured in advance, and further generate one or more power quality control instructions, such as a power quality control instruction for high-low voltage treatment, harmonic treatment, or voltage flicker suppression, for the existing power quality problem.
It should be noted that, if it is found that power quality control is not required in the edge internet of things proxy device, the first power quality control instruction is not generated, and at this time, step 102 and step 103 are not executed subsequently, and step 104 may be directly executed.
Step 103: and transmitting the first power quality control instruction to corresponding power quality control equipment in the first district, so that the power quality control equipment executes the first power quality control instruction.
The power quality management equipment in the embodiment is not required to be additionally provided with a special controller, and only needs to receive a first power quality control instruction output by the edge physical connection agent equipment and execute the first power quality control instruction to control power quality and realize power quality management and regulation.
For example, after generating a first power quality control instruction of reactive compensation according to the power quality data, the edge internet of things proxy device sends the first power quality control instruction of reactive compensation to the smart capacitor, and the smart capacitor executes the first power quality control instruction of reactive compensation, such as adjusting a compensation coefficient of the smart capacitor, so as to implement power quality management of reactive compensation. For another example, after the edge internet of things proxy device generates a first power quality control instruction of three-phase imbalance according to the power quality data, the first power quality control instruction of three-phase imbalance is sent to the phase change switch, and the phase change switch executes the first power quality control instruction of three-phase imbalance, for example, one phase load of a high load in three phases is distributed to one phase of a low load, so that power quality control of three-phase imbalance is realized.
It should be noted that, in this embodiment, after step 102 and step 103, the power quality monitoring device may be used to acquire the power quality data in the first area again, and then monitor the current power quality control effect of the edge agent of internet of things according to the power quality data, and determine whether the power quality control effect of the edge agent of internet of things in the first area meets the requirement, for example, whether three phases are balanced or harmonics still exist, and if the control effect does not meet the requirement, for example, three phases are still unbalanced or harmonics still exist, it indicates that effective power quality management cannot be implemented only by the power quality data in the first area, and at this time, the following schemes in step 104 to step 106 may be further executed to improve the reliability of power quality management.
Alternatively, in this embodiment, after step 101, the schemes in step 104 to step 106 may be directly executed to improve the reliability of the power quality control.
Step 104: and sending target data in the power quality data of the first station area to the cloud equipment.
The cloud device refers to a cloud platform of an electric power internet of things, and an application program, such as a platform area electric energy quality monitoring and treatment series micro application, is deployed on the cloud device, and the data processing function on the cloud device can be achieved through the application program. For example, on the cloud device, by executing the application program, data processing functions such as access of the edge internet of things agent device, data storage, data presentation, data mining, model training, instruction generation (decision assistance), and data sharing with other services in the cloud device in multiple zones can be realized.
Specifically, data transmission between the cloud device and the edge internet of things agent device in the first station area may be implemented through a remote communication network, as shown in fig. 2, the cloud device may implement data transmission between the cloud device and the edge internet of things agent device in each station area through the remote communication network. Based on this, in step 103, the edge internet of things agent device in the first platform area may send the target data in the platform area to the cloud device through the remote communication network.
It should be noted that the target data sent to the cloud device in step 104 may be the power quality data initially acquired in step 101, or may also be partial data in the power quality data of the appointed distribution room, or may also be data obtained after the edge internet of things device performs operations such as preprocessing and extraction on the power quality data initially acquired.
Step 105: and receiving at least one second power quality control instruction generated by the cloud equipment according to the target data of the first station area and the target data of at least one second station area based on a preset second power quality control rule.
Specifically, the edge internet of things agent device in the first station area may receive, through the remote communication network, the second power quality control instruction generated by the cloud device.
It should be noted that the second distribution area is another distribution area different from the first distribution area in the power distribution network, and is not particularly limited to a certain distribution area, where the cloud device generates at least one second power quality control instruction according to the target data of the first distribution area and the target data of at least one second distribution area, which can be understood as: the cloud device generates a second power quality control instruction according to the target data of all the corresponding distribution areas, or may also understand that: the cloud device generates a second power quality control instruction according to target data of part of all the corresponding transformer areas, wherein the part of the transformer areas comprises the first transformer area and other second transformer areas different from the first transformer area. Therefore, the cloud device integrates the target data of the first station area and other one or more second station areas different from the first station area, and then generates second power quality control instructions corresponding to all the integrated target data based on the second power quality control rule.
For example, in this embodiment, the cloud device sorts the target data such as voltage, harmonic, flicker, etc. of the first station area and the plurality of second station areas according to the quality item identifier, such as three-phase imbalance or harmonic, and then the cloud device processes the sorted power quality data such as voltage, harmonic, flicker, etc. based on the second power quality control rule configured in advance, and then generates one or more second power quality control instructions, such as power quality control instructions for high-low voltage governance, harmonic governance, or voltage flicker suppression. These second power quality control commands may be one or more, possibly including power quality control commands for one or more different power quality control types (quality item identifications), in another dimension, the second power quality control command may comprise power quality control commands for a cell or a plurality of different cells on the same or different power quality control types, for example, the second power quality control instruction may include a power quality control instruction only for the corresponding power quality control device in the first block, may also include a power quality control instruction only for the corresponding power quality control device in the second block, and may also include a power quality control instruction for the corresponding power quality control device in the first block and a power quality control instruction for the corresponding power quality control device in the second block at the same time. For example, the second power quality control command includes a power quality control command for three-phase imbalance in the first station area, and also includes a power quality control command for harmonics in the second station area, and so on.
The second power quality control rule on the cloud device can represent a control scheme which can be performed by the power quality control device when the power quality control instruction is executed, for example, different power quality control instructions are executed for different power quality data, so that different power quality control effects are realized. It should be noted that, in this embodiment, the second power quality control rule deployed on the cloud device may be the same as the first power quality control rule configured in each station, or the second power quality control rule deployed on the cloud device includes the first power quality control rule configured in each station. However, the first power quality control rule in each station is mainly used for processing the power quality data in the station where the first power quality control rule is located, so that the first power quality control instruction is generated on the edge internet of things proxy device, and the second power quality control rule on the cloud device is mainly used for comprehensively processing the power quality data in the plurality of stations, so that the second power quality control instruction is generated, so that the second power quality control instruction may be different from the first power quality control instruction due to the fact that the processed power quality data are different.
It should be noted that, in this embodiment, the second power quality control instruction received by the edge internet of things agent device of the first station is an instruction generated by the cloud device and directed to the power quality management device of the first station, and therefore, the cloud device sends the second power quality control instruction corresponding to the power quality management device of the first station to the edge internet of things agent device of the first station.
Step 106: and transmitting the second power quality control instruction to corresponding power quality control equipment in the first district, so that the power quality control equipment executes the second power quality control instruction.
Specifically, the edge internet of things agent device in the first station area may transmit the second power quality control instruction generated by the cloud device to the corresponding power quality management device in the first station area through the local communication network, and the power quality management device receiving the instruction executes the second power quality control instruction. Certainly, if a second power quality control instruction for the second station area is generated on the cloud device, the cloud device may also transmit the second power quality control instruction to the corresponding edge internet of things agent device of the second station area, at this time, the edge internet of things agent device of the second station area transmits the second power quality control instruction generated by the cloud device to the corresponding power quality control device in the second station area through the local communication network, and the power quality control device receiving the instruction executes the second power quality control instruction.
For example, after the edge internet of things agent device in the platform area generates the first power quality control instructions based on the power quality data, the power quality control instructions are transmitted to the power quality management device in the platform area through the local communication network, so that the power quality management device executes the power quality control instructions for high-low voltage management, harmonic management or voltage flicker suppression; and if the power quality control effect achieved by the edge internet of things agent equipment based on the power quality data in the own station area is poor, the edge internet of things agent equipment can send the power quality target data such as voltage, harmonic and power received by the edge internet of things agent equipment to the cloud end equipment of the power internet of things cloud platform through the remote communication network, and receive second power quality control instructions such as high and low voltage governance, harmonic governance, voltage flicker suppression, voltage fluctuation reduction and the like generated by the cloud end equipment based on preset second power quality control rules according to the power quality target data such as voltage, harmonic and flicker of the first station area and the power quality target data such as voltage, harmonic and flicker of the second station area through the remote communication network, and further the first station area edge internet of things agent equipment can transmit the second power quality control instructions to the power quality governance equipment in the first station area through the local communication network, so that the power quality management equipment in the first district executes the second power quality control command.
According to the above scheme, in the power quality control method for the distribution room provided in the embodiment of the present application, after power quality data of the distribution room is obtained by the power quality monitoring device in the distribution room, the power quality data is sent to the edge internet of things proxy device to realize power quality monitoring of the distribution room, and first power quality control instructions corresponding to the power quality data can be generated based on the first power quality control rule, and then the first power quality control instructions can be transmitted to the corresponding power quality control devices to enable the power quality control devices to execute the first power quality control instructions, so that control on the power quality in the distribution room is realized based on the power quality data in the current distribution room; or after the power quality data of the transformer areas are obtained through the power quality monitoring devices in the transformer areas respectively in the transformer areas and the target data in the respective power quality data are sent to the cloud device through the edge internet of things proxy devices in the transformer areas, the edge internet of things proxy devices in the transformer areas can receive second power quality control instructions corresponding to the target data of the transformer areas generated by the cloud device based on the second power quality control rules, so that the second power quality control instructions sent by the cloud device can be transmitted to the corresponding power quality control devices in the respective transformer areas in the transformer areas, the power quality control devices can execute the second power quality control instructions, and the control of the power quality in the respective transformer areas can be realized based on the power quality data in the transformer areas. Therefore, in the embodiment, the control of the power quality management equipment in each distribution area can be realized through the edge internet of things agent equipment and/or the cloud equipment in each distribution area, so that the power quality management in each distribution area is realized, a special controller is not required to be arranged for each power quality management equipment in the distribution area, and the complexity of a distribution area equipment system can be reduced.
In one implementation, when generating at least one first power quality control command corresponding to the power quality data based on the first power quality control rule, step 101 may be implemented by the following manner, as shown in fig. 3:
step 301: and calculating the power quality data according to at least one preset power quality index corresponding to the power quality data to obtain a first calculation result corresponding to the power quality index.
The power quality index may be understood as a specific description of an aspect capable of measuring power quality, for example, main indexes for measuring power quality include voltage deviation, frequency deviation, voltage three-phase imbalance, harmonic and inter-harmonic, voltage fluctuation, voltage flicker, and the like.
Specifically, in this embodiment, the electric energy quality data such as the voltage, the current, the power and the like may be calculated according to preset electric energy quality indexes corresponding to the electric energy quality data such as the voltage, the current, the power and the like, so as to obtain calculation results such as a voltage rise to a certain threshold or range, a current too small to a certain threshold or range, a power too large to a certain threshold or range, and the like.
Step 302: and generating a first power quality control instruction corresponding to the first calculation result based on the first power quality control rule.
In a specific implementation, the first power quality control rule in this embodiment may include multiple rules, each rule includes a calculation result and a power quality control instruction corresponding to the calculation result, and after the first calculation result is obtained in this embodiment, a rule corresponding to the first calculation result may be searched in the first power quality control rule, and then the power quality control instruction in the searched rule is obtained and used as the first power quality control instruction corresponding to the first calculation result.
In an implementation manner of the first embodiment of the present application, before the target data is sent to the cloud device in step 104, the method in this embodiment may further include the following steps, as shown in fig. 4:
step 107: and receiving a data request sent by the cloud equipment.
The data request at least comprises quality item identifications of electric energy quality data required by the cloud equipment, such as quality item identifications of three-phase imbalance or harmonic waves, so as to represent that the electric energy quality data are required to be used in the cloud equipment and serve as a data base for corresponding electric energy quality control.
Specifically, in this embodiment, the edge internet of things proxy device may receive a data request sent by the cloud device through the remote communication network.
Based on this, when the target data is sent to the cloud device in step 104, the following method may be specifically implemented:
first, the power quality data corresponding to the command item identifier may be extracted from all the obtained power quality data of the first station area, for example, only the power quality data related to the three-phase imbalance is extracted from all the power quality data of the first station area, and the power quality data related to the harmonic processing is not required, and then, the target data corresponding to the quality item identifier in the power quality data is sent to the cloud device. It should be noted that the target data may be data obtained by preprocessing the edge internet of things agent device, such as removing noise data, extracting key values, and the like.
Specifically, in this embodiment, the edge internet of things agent device in the first station area may send the electric energy quality target data corresponding to the quality item identifier to the cloud device through the remote communication network.
In an implementation manner of the first embodiment of the present application, the power quality control rule configured in the respective edge internet of things agent device in each station area may be configured as needed, for example, the first power control rule configured in the edge internet of things agent device in the first station area may be configured in the following manner:
firstly, acquiring a preset power quality management configuration parameter of a first station area on edge Internet of things agent equipment, wherein the power quality management configuration parameter at least comprises a quality item identifier which needs power quality management, if the power quality management configuration parameter is pre-configured in the first station area, only three-phase unbalanced power quality management needs to be carried out, and at the moment, only the three-phase unbalanced quality item identifier is contained in the power quality management configuration parameter of the first station area; or the power quality control of three-phase unbalance and harmonic waves is needed to be carried out in the first district, and at the moment, the power quality control configuration parameters of the first district not only comprise the quality item identification of three-phase unbalance, but also comprise the quality item identification of harmonic waves. And then, configuring a first power quality control rule corresponding to the quality item identifications in the power quality governance configuration parameters in the edge Internet of things agent equipment. Therefore, in the embodiment, based on the power quality management requirement, the corresponding power quality control rule is configured in the edge internet of things agent equipment, and after the power quality control rule is configured in the edge internet of things agent equipment of the transformer area, the power quality in the transformer area can be effectively managed, so that flexible power quality management is realized, and cost consumption caused by configuration of unnecessary power quality control rules can be avoided.
Furthermore, the power quality monitoring equipment and the power quality control equipment configured in the first area correspond to quality item identifiers in power quality control configuration parameters. For example, only three-phase unbalanced power quality control needs to be performed in a first block area, at this time, only three-phase unbalanced quality item identifiers are included in power quality control configuration parameters of the first block area, and correspondingly, power quality monitoring equipment capable of acquiring power quality data corresponding to the three-phase unbalanced quality item identifiers and power quality control equipment capable of executing related power quality control instructions of three-phase unbalance are configured in the first block area; or the power quality management equipment which needs to carry out three-phase unbalance and harmonic wave power quality management is configured in the first area in advance, at the moment, the power quality management configuration parameters of the first area not only comprise the quality item identification of the three-phase unbalance, but also comprise the quality item identification of the harmonic wave, correspondingly, the power quality monitoring equipment which can acquire the power quality data corresponding to the quality item identification of the three-phase unbalance, and the power quality monitoring equipment which can acquire the power quality data corresponding to the quality item target identification of the harmonic wave are configured in the first area, meanwhile, the power quality management equipment which can execute the related power quality control instruction of the three-phase unbalance management and the power quality management equipment which can execute the related power quality control instruction of the harmonic wave management are configured in the first area.
Referring to fig. 5, a flowchart of a power quality management method for a distribution room provided in the second embodiment of the present application is shown, where the method may be applied to the cloud device shown in fig. 2, where a data connection is established between the cloud device and edge internet of things proxy devices in at least two distribution rooms, as shown in fig. 2, a data connection is established between the cloud device and an edge internet of things proxy device in each distribution room in a power distribution network through a remote communication network.
Specifically, the method in this embodiment may include the following steps:
step 501: and receiving at least one item of target data sent by each edge Internet of things agent device.
The target data is part or all of the preprocessed power quality data in the power quality data obtained by the edge Internet of things agent equipment by using the power quality monitoring equipment in the corresponding distribution room. The target data may include, but is not limited to, one or any plurality of voltage, current, frequency, harmonic, ripple, flicker, power, and the like. It should be noted that the power quality control configuration parameters in each station area may be different, so the types of the power quality monitoring devices in each station area may be different, and correspondingly, the target data sent to the cloud device by the edge internet of things agent device in each station area may be different. For example, the target data sent to the cloud device by the edge internet of things agent device in the first station area includes both power quality data related to three-phase imbalance and power quality data related to harmonic, and the target data sent to the cloud device by the edge internet of things agent device in the second station area or other station areas different from the first station area may only include the power quality data related to three-phase imbalance or may only include the power quality data related to harmonic.
It should be noted that, for specific implementation of the power quality monitoring device, the edge internet of things agent device, and the power quality management device related to the following embodiments, reference may be made to the corresponding contents in the foregoing embodiments, and details are not described here.
Specifically, data transmission is carried out among the edge internet of things agent equipment, the power quality monitoring equipment and the power quality treatment equipment belonging to the same distribution room through a first communication network, and data transmission is carried out between the cloud equipment and the edge internet of things agent equipment in each distribution room through a second communication network.
For example, the cloud device may receive, through the remote communication network, power quality target data such as voltage, harmonic, power, and the like, sent by the edge internet-of-things agent device in the distribution area, where the power quality target data is obtained by the intelligent distribution terminal by using the intelligent primary device in the distribution area to which the cloud device belongs.
Step 502: and generating at least one second power quality control instruction according to the target data of each distribution area based on a preset second power quality control rule.
Based on this, the cloud device generates at least one second power quality control instruction according to the target data of each station based on the second power quality control rule, which can be understood as: the cloud device generates a second power quality control instruction according to the target data of all the corresponding distribution areas, or may also understand that: and the cloud equipment generates a second power quality control instruction according to the target data of part of the corresponding transformer areas in all the transformer areas. Therefore, the cloud device integrates the target data of at least part of the distribution areas in the power distribution network, and then generates second power quality control instructions corresponding to all the integrated target data based on the second power quality control rule.
For example, in this embodiment, the cloud device sorts target data such as voltage, harmonic, flicker, and the like of each of the multiple distribution areas according to quality item identifiers, such as three-phase imbalance or harmonic, and then the cloud device processes the sorted power quality data such as voltage, harmonic, flicker, and the like based on a second power quality control rule configured in advance, and then generates one or more second power quality controls, such as a power quality control command for high-low voltage control, harmonic control, or voltage flicker suppression. These second power quality control commands may be one or more, possibly including power quality control commands for one or more different power quality control types (quality item identifications), in another dimension, the second power quality control command may comprise power quality control commands for a cell or a plurality of different cells on the same or different power quality control types, for example, the second power quality control instruction may include a power quality control instruction only for the corresponding power quality control device in the first block, may also include a power quality control instruction only for the corresponding power quality control device in the second block, and may also include a power quality control instruction for the corresponding power quality control device in the first block and a power quality control instruction for the corresponding power quality control device in the second block at the same time. For example, the second power quality control command includes a power quality control command for three-phase imbalance in the first station area, and also includes a power quality control command for harmonics in the second station area, and so on.
It should be noted that the second power quality control rule on the cloud device can represent a control scheme that the power quality control device can perform when executing the power quality control instruction, for example, different power quality control instructions are executed for different power quality data, so as to achieve different power quality control effects. It should be noted that, in this embodiment, the second power quality control rule deployed on the cloud device may be the same as the first power quality control rule configured in each station, or the second power quality control rule deployed on the cloud device includes the first power quality control rule configured in each station. However, the first power quality control rule in each station is mainly used for processing the power quality data in the station where the first power quality control rule is located, so that the first power quality control instruction is generated on the edge internet of things proxy device, and the second power quality control rule on the cloud device is mainly used for comprehensively processing the power quality target data in the plurality of stations, so as to generate the second power quality control instruction.
