[0045] In order to make the objectives, technical solutions, design methods and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings through specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and do not limit the present invention.

[0046] Embodiment 1

[0047] Referring to Figures 1 to 2 , the present invention provides a power information security risk control method, including: obtaining the operating state of the power systems of each branch line of a transmission line;

[0048] Calculating the load access capacity of each branch line load control device according to the operating state of the power system;

[0049] Adjusting the number of loads connected to the branch line load control device according to the load access capacity of the branch line load control device and the operating state of the power system.

[0050] In the above, obtaining the operating state of the power systems of each branch line includes:

[0051] The load level set for the power system load level;

[0052] Judge the output configuration margin of the power system according to the load level.

[0053] In the above, the load level of the power system is the sum of the electric energy consumed by the loads under the branch lines corresponding to the current moment from the power system at the current moment, and can be monitored and obtained by the monitoring equipment set on the branch lines.

[0054] In the above. When obtaining the operating states of the power systems of each branch line, it also includes:

[0055] Calculate the load value of the operating capacity of the power system of the corresponding branch line according to the operating parameters of the power systems of each branch line received, and determine the operating states of the power systems of each branch line according to the load value;

[0056] When the load value exceeds the first threshold, generate a load regulation signal and transmit the load regulation signal to the corresponding branch line load control equipment. It should be noted that when the total electric energy transmitted by the transmission line is generally unchanged, the loads that can be connected to all the branch lines under the transmission line are basically constant. In order to make the transmission line in a relatively stable state, the total electric energy obtained by the loads cannot be greater than the total electric energy transmitted by the transmission line. Excluding the electric energy loss on the transmission line, generally, the total electric energy obtained by the loads cannot exceed 80% of the total electric energy transmitted by the transmission line. Therefore, the load value of the operating capacity of the power system of the branch line cannot exceed 80% of the total electric energy of the branch line that the branch line can supply.

[0057] In the above, calculating the load access capacity of each branch line load control equipment includes:

[0058] Obtain the operating parameters of the power systems of each branch line to calculate the load value of the operating capacity of the corresponding branch line power system;

[0059] Calculate the load level set according to the load value;

[0060] Judge the output configuration margin of the power system according to the load level;

[0061] Calculate the existing access capacity of each branch line load control equipment according to the load level;

[0062] Calculate the access capacity margin of each branch line load control equipment according to the output configuration margin;

[0063] Calculate the load access capacity of each branch line load control equipment according to the existing access capacity and the access capacity margin.

[0064] Among them, obtaining the operating parameters of the power systems of each branch line mainly includes the total electric energy that the branch line can supply and the electric energy margin.

[0065] In the above, when receiving the operating parameters of the power systems of each branch line, if it is detected that the operating parameters of the power systems of each branch line deviate and the deviation state is within the adjustable range, the operating parameters of the power system are adjusted to within the standard operating parameter range corresponding to the branch line.

[0066] In the above, the load value of the operating capacity of the power system of the branch line cannot exceed 80% of the total power energy that the branch line can supply. At this time, the operating parameters of the power systems of each branch line do not deviate. When it exceeds 80% of the total power energy of the branch line, it is considered to deviate. In order to enable the adjustment of the operating parameters of the power system, in this application, the load of the power systems of each branch line is adjusted to a certain extent, and the adjustable range cannot exceed 3% of the number of loads.

[0067] In the above, the load access capabilities of each branch line are judged. If the sum of the load access capabilities of any two branch lines is lower than the set standard threshold, the number of loads connected to the corresponding branch line load control device is adjusted so that the load access capabilities of the corresponding branch lines are maintained within the set balanced range. The balanced capacity range of the load access of each branch line is determined according to the load access capabilities of the branch line load control devices, and the balanced capacity range of the single branch line load control device is set to have an adjustable range set according to the load access situation; the standard threshold refers to the minimum requirement of the safe range set after adjusting the balanced capacity range of the single corresponding balanced capacity range of any two branch line load control devices according to the load access situation according to the adjustable range.

[0072] A load adjustment module, configured to adjust the number of loads connected to the branch line load control device according to the load access capabilities of the branch line load control device and the operating status of the power system.

[0073] Further, the monitoring module includes:

[0074] A load level calculation module, which sets the load level for the load level of the power system;

[0075] An output configuration margin calculation module for judging the output configuration margin of the power system according to the load level.

[0076] Furthermore, the monitoring module further includes:

[0077] A first trigger module for detecting the load value of the operating capacity of the power system of the branch line received, generating a load regulation signal when the load value exceeds a first threshold, and triggering the monitoring module to obtain the operating states of the power systems of the respective branch lines;

[0078] A second trigger module for periodically detecting the operating capacity of the power system on the main line of the transmission line according to a preset time period, and judging the upper limit value of the allocated operating states of the power systems of the respective branch lines based on the operating capacity of the power system on the main line of the transmission line;

If the sum of the load access capabilities of any two branch lines is lower than a set standard threshold, the number of loads connected to the load control devices of the corresponding branch lines is adjusted so that the load access capabilities of the corresponding respective branch lines are maintained within the set balance range.

[0083] Furthermore, the second load regulation unit includes: an adjustable range setting module for determining the balanced capacity range of the load access of each branch line according to the load access capabilities of the load control devices of the respective branch lines, and setting the balanced capacity range of the single branch line load control device to have an adjustable range set according to the load access situation.

[0084] The present invention monitors the operating states of the power systems of the respective branch lines of the transmission line in real time, thereby calculating the load access capabilities of the load control devices of the respective branch lines according to the operating states of the power systems; according to the load access capabilities of the branch line load control devices and the operating states of the power systems, the number of loads connected to the branch line load control devices is adjusted. Thus, the load access capabilities of the corresponding respective branch lines are maintained within the set balance range.

[0085] In the above, the load level of the power system is the sum of the electrical energy consumed by the loads under the branch lines corresponding to the current moment from the power system at the current moment, and can be monitored and obtained by the monitoring devices arranged on the branch lines.

[0086] In the above. When obtaining the operating states of the power systems of each branch line, it further includes: calculating the load value of the operating capacity of the power system of the corresponding branch line according to the received operating parameters of the power systems of each branch line, and determining the operating states of the power systems of each branch line according to the load value; generating a load regulation signal when the load value exceeds the first threshold, and transmitting the load regulation signal to the corresponding branch line load control device. It should be noted that when the total electrical energy transmitted by the transmission line is generally unchanged, the loads that can be connected to all the branch lines under the transmission line are basically constant. In order to make the transmission line be in a relatively stable state, the sum of the electrical energy obtained by the loads cannot be greater than the total electrical energy transmitted by the transmission line. Excluding the electrical energy loss on the transmission line, generally, the sum of the electrical energy that the loads can obtain cannot exceed 80% of the total electrical energy transmitted by the transmission line. Therefore, the load value of the operating capacity of the power system of the branch line cannot exceed 80% of the total electrical energy of the branch line that the branch line can supply.

[0087] In the above, calculating the load access capacity of each branch line load control device includes: obtaining the operating parameters of the power systems of each branch line to calculate the load value of the operating capacity of the power system of the corresponding branch line; calculating the load level set by the power system load level according to the load value; judging the output configuration margin of the power system according to the load level; calculating the existing access capacity of each branch line load control device according to the load level; calculating the access capacity margin of each branch line load control device according to the output configuration margin; calculating the load access capacity of each branch line load control device according to the existing access capacity and the access capacity margin.

[0088] Among them, obtaining the operating parameters of the power systems of each branch line mainly includes the total electrical energy that the branch line can supply and the electrical energy margin.

[0089] In the above, when receiving the operating parameters of the power systems of each branch line, when detecting whether the operating parameters of the power systems of each branch line deviate and the deviation state is within the adjustable range, adjusting the operating parameters of the power system to within the standard operating parameter range corresponding to the branch line.

[0090] In the above, the load value of the operating capacity of the power system of the branch line shall not exceed 80% of the total electric energy that the branch line can supply. At this time, the operating parameters of the power system of each branch line do not deviate. When it exceeds 80% of the total electric energy of the branch line, it is considered that a deviation has occurred. In order to enable the adjustment of the operating parameters of the power system, the present application makes a certain adjustment to the load through the power system of each branch line, and the adjustable range shall not exceed 3% of the number of loads.
