As in the system of the present invention, the substation server 1 configures a communication mode for communication with each of the transformation data processors 14.
When the substation server 1 receives the transformation data packet sent by the transformation data processor 14, the transformation data processor 14 packages the transformation data and sends the transformation data packet to the substation server 1 in a data packet communication mode;
and the substation server 1 adopts an instruction packet communication mode to send a control instruction packet to the transformation data processor 14. The transformation data processor 14 analyzes the control command packet according to the command packet communication mode, and executes the control command.
The packet communication mode uses a data communication channel for communication, and performs communication based on a communication channel having a low delay and a large communication data amount in a communication network.

when the E-grade insulating material is adopted, the maximum temperature rise is less than 75K when the ultimate working temperature is 120 ℃;

when the C-grade insulating material is adopted, the maximum temperature rise is less than 150K when the ultimate working temperature is 220 ℃.
When the F-grade insulating material is adopted, the maximum temperature rise is less than 100K when the ultimate working temperature is 155 ℃;
when the H-grade insulating material is adopted, the maximum temperature rise is less than 125K when the ultimate working temperature is 180 ℃.
Of course, the electric elements such as the electric switch and the relay have proper working temperature.
When monitoring the electric elements in the transformer substation, the monitoring can be performed based on outdoor environment information and combined with indoor environment temperature information.
Namely, the temperature monitoring state diagram of the electric element is configured by combining the outdoor environment information, the indoor environment temperature information and the temperature state of the electric element.
The temperature monitoring state diagram of the electric element comprises the temperature, the humidity and the humidity range which meet the normal work of the electric element. The substation server 1 may determine whether the substation operates within the threshold range based on environmental information in which the substation is located, indoor temperature information, and an electrical element temperature monitoring state diagram.
According to the invention, the temperature monitoring state diagram of the electrical element is configured based on the comparison of the temperature inside the box body and the temperature outside the box body and the current electrical element conforming state, so that the prior configuration mode of the transformer substation can be corrected, and the actual monitoring requirement can be met. The invention solves the problem that the monitoring parameters can not be effectively corrected based on environment and load information due to the simplification of the temperature monitoring process in the prior art, so that the box-type substation 2 can stably work within the preset temperature and humidity range.
In the embodiment provided by the invention, the transformer substation server 1 judges whether the relationship among the external environment data information of the transformer substation, the temperature and humidity information of each electrical device and the internal data information of the transformer substation conforms to the temperature monitoring state diagram of the electrical element through the meteorological sensor 13;
if the temperature monitoring state diagram of the electrical element is not met, whether external environment data information of the transformer substation is matched with the temperature and humidity information of each electrical device is analyzed;
whether the temperature and humidity information of each electrical device is matched with the internal data information of the transformer substation or not is judged;
whether the external environment data information of the transformer substation is matched with the internal data information of the transformer substation or not is judged;
if the matching information does not meet the preset condition, adjusting the data information which does not meet the preset condition;
and comparing and judging with the temperature monitoring state diagram of the electric element again after adjustment.
For example, the outdoor temperature is 30 ℃, the internal temperature of the transformer substation is 38 ℃, the difference value between the outdoor temperature and the internal temperature of the transformer substation is 8 ℃, if the temperature difference is more than 3 ℃ and is a preset condition, and the internal temperature of the transformer substation cannot exceed 18 ℃, the data information which does not accord with the preset condition is adjusted;
and the substation server 1 adopts a control instruction packet sent to the substation data processor 14 in an instruction packet communication mode. The transformation data processor 14 analyzes the control command packet according to the command packet communication mode, executes the control command, and controls the environment control device 11.
For another example, if the current maximum operating temperature of a certain electrical component is changed, that is, the maximum operating temperature is reduced, the maximum operating temperature of the electrical component is changed by the substation server 1.
The transformer substation server 1 acquires external environment data information of the transformer substation, and whether the relationship among the temperature and humidity information of each electrical device and the internal data information of the transformer substation conforms to an electrical element temperature monitoring state diagram or not through the meteorological sensor 13;
if the temperature monitoring state diagram of the electrical element is not met, whether external environment data information of the transformer substation is matched with temperature and humidity information of each electrical device is analyzed;
whether the temperature and humidity information of each electrical device is matched with the internal data information of the transformer substation or not is judged;
whether the external environment data information of the transformer substation is matched with the internal data information of the transformer substation or not is judged;
if the matching information does not meet the preset condition, adjusting the data information which does not meet the preset condition;
here, the operation maximum temperature of the electric element is adjusted, and the electric element temperature monitoring state diagram is adjusted after the operation maximum temperature of the electric element is satisfied.
As another example, the weather sensor 13 senses that the relative humidity of the external environment is 70%,
the environmental conditioning unit 11 of the system is activated to a relative humidity maximum of 50%, if the relative humidity inside the substation exceeds 50%.
For the temperature monitoring state diagram of the electrical element, the relative humidity configuration range is 45% -65%, the environment adjusting device 11 performs dehumidification operation under the environment, and the environment adjusting device 11 reduces the relative humidity inside the transformer substation to the relative humidity range of 45% -65% of the temperature monitoring state diagram of the electrical element, so that the requirement of the electrical element on humidity is met, and the requirement of stable operation of the transformer substation is also met.
The transformer substation server 1 sends a time check instruction packet to the transformer substation data processor 14 through an instruction packet communication mode, and records the current sending time as a first service sending time;
the power transformation data processor 14 receives the time check instruction packet through the instruction packet communication mode, and records the current receiving time as the first power transformation data receiving time;
the power transformation data processor 14 sends a feedback verification instruction packet to the substation server 1 in an instruction packet communication mode, and records the current sending time as second service sending time;
the transformer substation server 1 receives the feedback check instruction packet and records the current receiving time as second transformer data receiving time;
the transformation data processor 14 configures a transformation data communication time difference with the transformation data processor 14;
the calculation mode of the power transformation data communication time difference is as follows: a first difference value between the first power transformation data receiving time and the first service sending time, and a second difference value between the second power transformation data receiving time and the second service sending time; the average of the first difference and the second difference is the communication time difference of the power transformation data.
The invention can calculate the time difference of communication between the substation server 1 and the transformation data processor 14, and can improve the accuracy and timeliness of communication between the substation server 1 and the substation. The stable work of avoiding influencing power supply distribution influences the regional power consumption state of power supply distribution.
That is to say, in the communication process between the substation server 1 and the substation data processor 14, the substation data is configured uniformly, and the time between communications is synchronized, so that the time length in the communication process is prevented from exceeding the threshold value. If the substation server 1 obtains the transformation data with the time length exceeding the threshold, the transformation data may be retransmitted to the transformation data processor 14, so that the transformation data processor 14 retransmits the transformation data packet with the time length exceeding the threshold based on the preset format preset communication mode, and may also transmit the transformation data packet in the current operation state. The substation server 1 communicates and analyzes the substation data packet, judges whether the communication is over-long, ensures that the data communication and processing process of the substation have a uniform format and mode, ensures that data can be smoothly transmitted between the substation server 1 and the substation data processor 14, and ensures that the data is timely, comprehensive and complete.
