Description

  The present invention provides an electric accident information providing system that notifies a power user in real time of information such as the time of occurrence, place of occurrence, degree, and influence range when an instantaneous voltage drop due to an instantaneous voltage drop or a lightning strike occurs. The present invention relates to an electrical accident information provision method and an electrical accident information provision program.

Conventionally, when an electrical accident such as an instantaneous voltage drop due to a lightning strike occurs somewhere, obtain detailed information such as the time of occurrence, place of occurrence, degree and affected range, and determine the extent of the electrical accident and the affected range. The only way to identify and notify customers was to arrange a large number of managers who monitor substations, etc., and manually investigate and notify power consumers. As a conventional technique, a technique for predicting the occurrence of an instantaneous voltage drop due to a lightning strike is proposed in which lightning strikes are predicted in advance and the prediction information is provided to power consumers. For example, Document 1 describes a method for providing information to a user based on lightning strike information predicted in advance. Further, Document 2 describes a method for notifying a user whether or not there is a possibility of an instantaneous power failure based on lightning strike position information.

The central processing unit 21 of the substation 2 performs the following operations periodically, for example. In the present embodiment, first, on / off information of the circuit breaker 24 is acquired and held as data (S71). Next, the operation status of “with operation” and “without operation” of the protective relay 26 is acquired and held as data (S72).

Next, similarly, the operation status of “with operation” and “no operation” of the protection relay 26 in the substation 2 is acquired and input to the monitoring information DB 74 (S13). Finally, the time at which the monitoring information from the substation 2 is received is acquired from the clock unit 15 and input to the monitoring information DB 74 (S14).

Therefore, the system information collecting means 63 first collects the open / close state of the switch of each system from the monitoring information system 8 to specify the influence range of the electrical accident, and inputs it to the system information DB 75 (S21). Next, the time when the open / close state of the switch is collected is acquired from the clock unit 15 and input to the system information DB 75 in the system information DB 75 (S22). The above operation is performed for all switches present in all systems (S23).

  FIG. 11 shows an operation flow of the instantaneous voltage drop specifying means 65 having a function of determining that an instantaneous voltage drop has occurred. In the present embodiment, the bus voltage change value, the line current change value, and the zero-phase voltage change value notified from the substation 2 are actual values at the time of measurement, not the change values compared with the previous time. It is. In the present embodiment, the change is obtained by calculating the difference between the bus voltage value at the time of measurement, the line current value, the zero-phase voltage value, and the previous measurement value. First, the change value of the bus voltage at a certain time is calculated from the previous bus voltage value from the monitoring information DB 74 and stored as data (S31). Next, similarly, the change value of the line current from the previous time is calculated and stored as data (S32). Next, the change value of the zero-phase voltage is calculated by comparing with the previous value and stored as data (S33).

  Further, on / off information of the circuit breaker 24 is extracted (S34), and the operation status of the protection relay 26 "with operation" and "no operation" is extracted (S35). Then, the “instantaneous voltage drop determination routine” is started (S36). If it is determined that an instantaneous voltage drop has occurred according to the result of the “instantaneous voltage drop determination routine” (S37), the location, time, and extent at that time are output to the instantaneous drop information DB 76 (S38). The instantaneous drop specifying means 65 performs all the above determinations over all received monitoring information (S39). It is desirable that this instantaneous drop specifying means 65 is periodically performed in real time at a period for collecting monitoring information. Depending on the implementation, it is also possible to perform the monitoring with a period longer than the monitoring information acquisition period. Alternatively, when monitoring information is collected by interrupt control, it can be performed in accordance with the interrupt.

  In the present embodiment, the “instantaneous voltage drop determination routine” is configured to determine whether or not an instantaneous voltage drop has occurred by comparing the threshold value of each change value with a threshold value database (DB) 73. . In the present embodiment, first, it is determined whether or not a difference value, which is a change value of the bus voltage input as a parameter, exceeds a threshold value given in advance (S41). If the threshold value is exceeded, it is determined that an instantaneous voltage drop has occurred, and the process returns to the calling location of the instantaneous drop specifying means 65 that has called (S42). If the threshold is not exceeded, it is considered that no instantaneous voltage drop has occurred.

  FIG. 13 shows an operation flow of the influence range specifying means 64 for specifying the influence range when the instantaneous voltage drop occurs. First, the switching state of the switch in the system is traced for each power transmission line from the system information DB 75, and the connection state of the power transmission line is specified (S51). Next, the influence range is specified by calculating from the line characteristics and the back impedance of the power supply (S52). The customer ID connected to the power transmission line is extracted from the customer information DB 71 using the power transmission line or the distribution line ID as a search key, and the extracted customer ID is output to the voltage drop information DB 76 (S53).

  FIG. 14 shows an operation flow of the instantaneous voltage drop information providing unit 66 that notifies the customer that an instantaneous voltage drop has occurred. The influence range, occurrence location, occurrence time, and extent of the instantaneous voltage drop are specified by the above-described means. Customers in the target area of the instantaneous voltage drop specified by the instantaneous drop specifying means 65 and the influence range specifying means 64 are extracted (S61). As the instantaneous voltage drop information, the generation location, generation time, degree, and influence range are specified (S62). The notification means desired by the extracted customer is specified based on the customer information DB 71, and the process branches at each notification means (S63).

  The customer who is requesting notification by e-mail describes the occurrence time, occurrence location, extent, and influence range of the instantaneous voltage drop in the body of the e-mail, and automatically transmits it using e-mail software (S64). For customers requesting telephone notification, a telephone number is obtained from the customer information DB 71, and the time, location, degree, and range of influence of the instantaneous voltage drop are recorded by voice, and PBX, IP telephone device, etc. (Not shown) is automatically called and notified (S65). For customers requesting FAX notification, the FAX number is obtained from the customer information DB 71, and the location, time, degree, and influence range of the instantaneous voltage drop are automatically created, for example, automatically by PC software. A call is sent and notified by FAX (S66). In the case of notification by telephone or FAX, it is desirable that automatic processing such as calling is performed again when the customer encounters a busy line. This notification process is repeated for all customers (S67). It is also possible to notify the customer using a method other than the above e-mail, telephone, and FAX. With these various notification functions, it is possible to deal with customers having various notification means.

  As described above, in the present embodiment, the monitoring information notified from each substation 2 via the communication network 5 is received, the determination of the occurrence of the instantaneous voltage drop based on the monitoring information, and the occurrence It is possible to specify the range and extent of the instantaneous voltage drop, and further notify the customer of the occurrence of the specified instantaneous voltage drop in real time. Furthermore, change values such as voltage and current can be determined from bus voltage change values, line current change values, zero-phase voltage change values, circuit breaker on / off information, and protection relay operation on / off information. Therefore, it is possible to accurately determine whether or not an instantaneous voltage drop has occurred. In addition, trace the switching state of the switch as system information and specify in detail the range of influence of the instantaneous voltage drop from the line characteristics and the impedance behind the power supply. It is possible to accurately notify the affected customers. In addition, by selecting and using a unique or common procedure via e-mail, telephone, FAX, and communication network 5, it becomes possible to adapt to the customer's various equipment conditions regarding notification of occurrence information of instantaneous voltage drop. .

Next, a second embodiment will be described.
In the first embodiment, when an instantaneous voltage drop occurs, the occurrence is specified in real time, and the occurrence location, occurrence time, degree, and affected range are notified to an affected customer in real time. In the second embodiment, not only the instantaneous voltage drop but generally the situation and the degree of the occurrence of the power quality drop are detected in real time, the situation is notified to each power consumer, and the use of the power is notified by the notice. Points are given to electricity consumers who have reduced the amount of electricity consumed, based on the reduced amount of electricity used. The given points can be used as discount coupons at member stores. In addition, the present invention provides a mechanism for stabilizing power supply by having power consumers reduce power when the amount of power used reaches a peak. When giving points, it is also desirable for security to simultaneously notify the authentication code for authentication.

  FIG. 16 shows a functional block diagram of the electrical accident information provision system 1, the substation 2, the power consumer terminal 3, and the member store 4 in the second embodiment. 1 differs from FIG. 1 in that the member store 4 is added and the monitoring system 8 is omitted, and that the instantaneous low rank DB 77 and the member store information DB 78 are added as databases. This means that point authentication means 67, point service control means 68, and member store notification means 69 are added as means, and that a measured value of the amount of electric power 35 exists at the power consumer's house. Although the monitoring system 8 is omitted in FIG. 16, it exists. In the second embodiment, the member store 4 is a store or an agent store where an electric power consumer can use the points obtained when the instantaneous voltage drop occurs to purchase goods.

  Furthermore, the member store 4 can receive notification when an instantaneous voltage drop occurs. By providing the state of occurrence of the instantaneous voltage drop, it becomes possible to quickly detect the failure of the equipment of the electric power consumer and promptly notify the electric power consumer who has a high probability of occurrence of the fault to conduct business.

  FIG. 17 is a diagram for explaining a data flow for inputting various data, a data flow for monitoring information notification, and a notification data flow when an instantaneous voltage drop occurs. The difference from FIG. 2 is that the member store 4 or the electronic mall sales site of the member store 4 is included. The processing sequence shown in FIGS. 17 and 18 will be described below. The monitoring information is notified to the electrical accident information providing system 1, and it is determined whether an instantaneous voltage drop has occurred or the power consumption has reached a peak by comparing the value of the monitoring information with threshold data. When it is specified that an instantaneous voltage drop has occurred, the information is notified to the power consumer and the member store 4. In addition, the notification can be received when the power consumption reaches a peak. In response to the notification that the power usage has reached the peak, the power consumer reduces the power usage.

  The member store 4 identifies a power consumer who is a customer who seems to have been damaged by the occurrence of an instantaneous voltage drop, and accesses the identified power consumer by, for example, sending an e-mail to urge the purchase of goods. Information may be transmitted and received systematically via the communication network 5 as well as mail. The electric power consumer who has received access browses the electronic mall sales site of the member store 4 or the like. This electronic mall may be WWW contents published on the Internet, or may be a unique system as the electrical accident information providing system 1. When the instantaneous voltage drop occurs, the electrical accident information provision system 1 monitors the amount of power consumed by the power consumer, measures the amount of power reduction, and calculates points that are given in stages depending on the degree of the instantaneous voltage drop. Then, the electrical accident information providing system 1 notifies the calculated point to the power consumer. The electric power consumer can use the points to purchase goods at the member store 4.

  When goods are purchased at points, the operation is performed so as to subtract the points consumed from the customer information of the electric power consumer. Similarly, when it is determined that the power usage has reached the peak, as shown in FIG. 18, the electrical accident information providing system 1 reduces the power consumption because the power usage is approaching the peak for the power consumer. Request for cooperation. The power consumer who has received the power reduction request performs power reduction, and the electrical accident information providing system 1 measures the reduction result. Points that can be used at the member store 4 or the like are given to the electric power consumer based on the measured reduction result, and the electric power consumer is notified. Electricity consumers can use points at the electronic mall of the member store 4 or the like. Similarly, it can be used in stores. When purchased, the point used by the power consumer from the electronic mall of the member store 4 is notified to the electrical accident information providing system 1, and the points owned by the power consumer are subtracted to notify the current point to the power consumer. . Receiving the point notification, the power consumer terminal 3 performs processing such as displaying the received point on the screen.

  The peak of power can be determined by comparison with past results, demand trends, and the like. For past performance, the average for the past several years, the comparison of the same month of the previous year with the current month, the average of the day of the month for the past several years and holidays, and the day of the week for the same month of the previous year, and holidays And can be predicted. Further, the demand trend can be predicted from the weather situation or the change in the weather when reaching the past peak. It is also possible to perform prediction by mixing and computing the two prediction methods. In addition, when the maximum supply amount of power equipment is approached, a power reduction request is made to a power consumer.

  FIG. 19 shows the configuration of the customer information DB 71. What is different from FIG. 3 is that point information is added. Points that the customer has can be used for purchasing products at the member store 4.

  FIG. 20 shows the configuration of the instantaneous drop rank DB 77. The instantaneous drop rank DB 77 is a rank of the degree of the instantaneous voltage drop when the instantaneous voltage drop occurs, and is ranked according to the degree of the instantaneous voltage drop. The degree of the instantaneous voltage drop is linked to the threshold value DB 73 described in the first embodiment.

FIG. 21 shows the structure of the member store information DB 78. Each member store 4 is managed by a member store ID, and further includes a member store name, its business type, a contact mail address of the member store, a telephone number, an address, a power transmission line ID, and the like.
Compared with the first embodiment, the second embodiment is configured with the components added as described above.

  Hereinafter, a description will be given of parts different from the first embodiment. 22 and 23, when an instantaneous voltage drop occurs and when the power consumption reaches a peak, the power consumer is notified of the occurrence, the subsequent power usage is monitored, and the power usage reaches a peak. The operation | movement flow of the point recognition means 67 which performs the recognition of the point provided with respect to an electric power consumer according to the electric power consumption which the electric power consumer reduced at the time of is shown. This will be described with reference to FIGS. First, it is determined whether or not an instantaneous voltage drop has occurred (S101). If not, it is then determined whether or not the power consumption is reaching a peak (S102). This determination is made in real time by periodic or interrupt processing.

  If there is an instantaneous voltage drop, list the power consumers who used the power when the instantaneous power failure occurred (S103), and point the target person according to the amount of power used by the target power consumer. Calculate (S104). Next, a customer ID and points are calculated in consideration of customer identification and security to generate an authentication code (S105). The calculation method of this calculation is not limited to the combination of customer ID and point, but may be a method of combining various values that can identify the customer, such as calculation using the MAC address and point value of the customer's LAN card. Thereafter, the customer is notified of the calculated authentication code and the member store information if necessary (S106).

  Next, the customer is notified. As described above, the notification method includes the use of e-mail (S107), the use of a telephone (S108), and the use of FAX (S109). The point notification is performed for all the customers who acquire the points (S110). Next, a point calculation method after notifying that the power usage amount is reaching the peak will be described with reference to FIG. The amount of electric power used by the electric power consumer after the notification of the electric power consumer at a certain point in time when the electric power consumption exceeds the peak is calculated (S121). Points are calculated according to the calculated electric energy (S123). When calculating the points, it is possible to take into account the content of the power contract such that a power consumer with a large contract capacity can obtain more points.

  The next operation S106 to S110 performs the same operation as described above. The customer can purchase various products from the member store 4 using the acquired points. The authentication code is notified at the time of payment of the purchased product. For example, in the case where all electronic points can be purchased, for example, at the sales site in the electronic mall of the member store 4 shown in FIG. 27, the customer signs in to the site using an ID, password, etc. It is possible to use a method of automatically displaying the points possessed by and using the points as a payment method when selecting a product to be purchased.

  FIG. 24 shows an operation flow of the member store notification means 69 for notifying the member store 4 of the information in addition to the power consumer when the instantaneous voltage drop occurs. Among the member stores 4, the member store 4 that is desired to be notified when an instantaneous voltage drop occurs is registered in advance in a storage area or the like in the electrical accident information providing system 1. Alternatively, the customer information DB 71 may be provided with a notification flag indicating whether or not to notify when an instantaneous voltage drop occurs, and the flag may be determined for each customer (FIG. 28).

  The member store notification means 69 first extracts the member store 4 that is requesting notification of the occurrence of an instantaneous voltage drop (S131). In this embodiment, this is done by retrieving a notification flag from the customer information DB 71. Next, a method of notifying the extracted member store 4 is extracted (S132). In this embodiment, the notification method includes e-mail, telephone, FAX, and a unique procedure, which can be selected for each customer. Steps S135, S136, and S137, which are notification steps using e-mail, telephone, and FAX, are the same as the methods described in steps S107, S108, and S109, respectively.

  In the notification method using the unique procedure, the point to be notified and the authentication code are delivered as the unique procedure data, and are sent as data in accordance with the unique procedure defined between the member store 4 and the electrical accident information providing system 1 (S134). ). In consideration of security, the content of data is encrypted using a key such as a public key number such as RSA and a secret key number such as DES, SSL (Secure Socket Layer) or IKE that performs encryption as a communication protocol. It is desirable to send encrypted data by using IP-SEC using protocols such as (Internet Key Exchange), ESP (Encapsulating Security Payload), and AH (Authentication Header). The above series of operations is performed on all member stores 4 that have been extracted (S138).

  FIG. 25 shows a power quality determination routine for determining the power quality. In this routine, the bus voltage change value, line power change value, zero-phase voltage change value, circuit breaker on / off information, and operation status of the protective relay 26 obtained as monitoring information are all investigated, and according to the arithmetic expression. This is a routine for judging the quality of electric power. Specifically, first, it is determined whether the bus voltage change value exceeds a threshold value (S141). If it exceeds, the bus voltage flag is turned on (S142).

  Next, it is determined whether or not the line current change value exceeds the threshold value (S143), and if it exceeds, the line current change flag is turned on (S144). Similarly, it is determined whether or not the zero-phase voltage change value exceeds the threshold value (S145), and if it exceeds, the zero-phase voltage change flag is turned on (S146). Next, on / off information of the circuit breaker 24 is determined (S147), and if it is off, the circuit breaker flag is turned on (S148). Similarly, the operation status of the protective relay 26 is determined (S149), and if it is “operating”, the protective relay flag is turned on (S150). The power quality rank is determined based on the above five pieces of information. (S151). Accurate power quality is determined based on the relevance of the above five pieces of information. When the quality of the provided electric power is low, the electric power company can be given a consciousness of supplying higher quality electric power by giving points to the electric power consumer.

  FIG. 26 is an operation flowchart of the point service control means 68 for processing the points used by the customer at the member store 4. In the present embodiment, the member store 4 can also communicate with the electrical accident information providing system 1 via the communication network 5. When a customer purchases a product from the member store 4 using the point service, the member store 4 is notified of the point usage status using, for example, an original procedure, and the customer uses how many points by using the information. (S161). It is desirable that the data transmitted and received at this time is encrypted. Next, the point service control means 68 subtracts the point value used by the customer this time from the customer information DB 71 as used (S162). The second embodiment is configured as described above, and by performing the point service, when a power usage amount reaches a peak, a mechanism is set up so that power consumers can control power consumption, Power supply can be stabilized.

  In the second embodiment, a power consumer can take measures by receiving notification of occurrence of power quality deterioration such as instantaneous voltage drop and the fact that power consumption has reached a peak. . Furthermore, points that can purchase goods and the like at member stores can be given to electric power consumers who have used electric power at the time of occurrence of power quality degradation. In addition, when the power usage is reaching its peak, it is notified to the power consumer, and the points are also given to the power reduction performed by the power consumer according to the amount of power reduction. It becomes possible to raise awareness of power reduction. 17, 18, 22, and 23 do not describe the provision of points for a decrease in power quality, the same operation is performed for power quality. In addition, this point increases the willingness of consumers to purchase electricity, and the member stores can benefit. In addition, a supplier who provides information such as power quality and power peak can obtain a price for providing information by collecting avoidance from the member store.

  Next, a third embodiment will be described. In this embodiment, the customer is not a power consumer but a power generation company. The customer information DB 71 shown in FIG. 28 is customer information of a power generation company, and an electric power provision rank is added. FIG. 29 shows the power generation classifier's instantaneous drop rank DB 77. Points for each rank are further ranked in the instantaneous drop rank DB 77 of the power generation company. This ranking is given by the quality of the power provided by the power generation company. Since the higher the quality of the power supplied, the higher points can be obtained, so the power generation company can be conscious of providing higher quality by applying this point system. FIG. 30 shows the operation of point recognition of the power generation company. The operation will be described below.

The power supply rank of the customer who is the power generation company is acquired from the customer information DB 71 (S171). This rank is given by the quality of the power supplied by the customer when the customer is supplying power. The higher the power quality, the higher the rank. The intention is to increase the number of customers who provide high-quality power. For example, a value of “0” is set when power is not provided. Next, points for each customer are calculated based on the instantaneous drop rank and the power supply rank obtained above (S172). For example, if the following formula is used, the value of 10 to 5 is obtained when the instantaneous drop rank = 10, the power supply rank = 1 to 10, and the customer who does not provide power is “0”.
Point = ("instantaneous low rank" x ("power supply rank" ÷ 20) + 5)
In the case of this example, the point of the customer who supplies high-quality power is high, and vice versa. In this case, the customer who is not supplying power has the lowest point value, but for such a point calculation method, if a value or calculation formula with higher execution efficiency is actually selected, good. The following steps 106 to S110 are the same as those described in the second embodiment.

  In the third embodiment, other operations are the same as those described in the second embodiment.

  In the first, second, and third embodiments, for example, by notifying the power consumer of power quality degradation information such as an instantaneous voltage drop, the power consumer can determine whether to install a factory, switch the power receiving line, It becomes possible to take measures for manufacturing due to partial stoppage of the production line, etc., and it is possible to prevent loss due to equipment damage or sudden stoppage of the line. In addition, it is possible to provide customers with instantaneous voltage drop information including instantaneous power outage information even for instantaneous power outages due to typhoons, etc., which was not possible with the previous lightning forecasting system, and also prevent instantaneous power outages due to typhoons. Measures can be taken. Furthermore, at a department store or the like, it is possible to avoid in advance human dangers associated with the stop of equipment such as an escalator due to an instantaneous voltage drop such as an instantaneous power failure.

 Needless to say, the present invention is not limited to the first, second, and third embodiments, and various modifications can be made without departing from the spirit of the present invention.

  The present invention can be used in the electric power industry.
