[0002] Traditional transmission lines consist of several branches, each of which is connected to different loads. Since the access of loads directly affects the operation of the transmission line and the power system installed on it, when too many loads are connected, it will cause undervoltage and thus failure. Since the load on the branch directly affects the operating status of the power system on the transmission line, it is necessary to monitor the operating status of the power system in real time so that the load on each branch can be effectively controlled. Summary of the invention

[0003] In view of this, the main purpose of the present invention is to provide a power information security risk management system and method.

[0004] The technical solution adopted by the present invention is as follows:

[0006] A method for controlling power information security risks, comprising:

[0007] Obtain the operating status of the power system of each branch of the transmission line;

[0008] Calculate the load access capacity of each branch line load control device according to the operating status of the power system;

[0009] According to the load access capability of the branch line load management and control device and the operating status of the power system, the number of loads accessed by the branch line load management and control device is adjusted.

[0010] Furthermore, the obtaining of the operating status of each branch line power system includes:

[0011] a load level set for the load level of the power system;

[0013] Furthermore, when obtaining the operating status of each branch line power system, it also includes:

[0014] Calculate the load value of the power system operation capacity of the corresponding branch line according to the received operation parameters of the power system of each branch line, and determine the operation state of the power system of each branch line according to the load value;

[0015] When the load value exceeds the first threshold, a load adjustment signal is generated, and the load adjustment signal is transmitted to the corresponding branch line load management and control device.

[0019] Determining the output configuration margin of the power system according to the load level;

[0020] Calculate the existing access capacity of the load control equipment of each branch line according to the load level;

[0021] Calculating the access capacity margin of the load control equipment of each branch line according to the force configuration margin;

[0022] Calculate the load access capacity of each branch line load control equipment based on the existing access capacity and access capacity margin.

[0023] Furthermore, when the operating parameters of the power system of each branch line are received, it is detected whether the operating parameters of the power system of each branch line deviate and if the deviation state is within an adjustable range, the operating parameters of the power system are adjusted to within the standard operating parameter range corresponding to the branch line.

[0024] Furthermore, the load access capacity of each branch line is judged. If the sum of the load access capacity 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 capacity of each corresponding branch line remains within the set balance range.

[0026] The standard threshold refers to the minimum requirement of the safety range set by any two branch line load control devices within the single corresponding balancing capacity range after adjusting according to the adjustable range based on the load access situation.

[0027] The present invention also provides a power information security risk management and control system, comprising:

[0036] The second trigger module is used to periodically detect the operating capacity of the power system on the main line of the transmission line according to a preset time period, and determine the upper limit value of the allocated operating state of the power system of each branch line according to the operating capacity of the power system on the main line of the transmission line;

[0037] The third trigger module is used to generate a state trigger signal of the power system when the corresponding monitoring equipment starts the monitoring of the operation status through the monitoring program of the power system, and when the operation status of the power system is unknown, to trigger the monitoring module to obtain the operation status of the power system of each branch line.

[0038] Furthermore, the load adjustment module includes:

[0039] A first load adjustment unit is used to adjust the operating parameters of the power system to within the standard operating parameter range corresponding to the branch line when the detected operating parameters of the power system deviate and the deviation state is within the adjustable range;

[0046] In order to make the purpose, technical solution, design method and advantages of the present invention clearer, the present invention is further described in detail by specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] Example 1

[0048] Reference Figure 1 to Figure 2 ,The present invention provides a method for power information security risk management and control, including: obtaining the operating status of the power system of each branch line of the transmission line;

[0049] Calculate the load access capacity of each branch line load control device according to the operating status of the power system;

[0050] According to the load access capability of the branch line load management and control device and the operating status of the power system, the number of loads accessed by the branch line load management and control device is adjusted.

[0051] In the above, the obtaining of the operating status of each branch line power system includes:

[0052] a load level set for the load level of the power system;

[0053] An output configuration margin of the power system is determined according to the load level.

[0054] In the above, the load level of the power system is the sum of the electric energy taken from the power system by the loads under the branch line corresponding to the current moment, which can be monitored and obtained by the monitoring equipment installed on the branch line.

[0055] In the above, when obtaining the operating status of each branch line power system, it also includes:

[0056] Calculate the load value of the power system operation capacity of the corresponding branch line according to the received operation parameters of the power system of each branch line, and determine the operation state of the power system of each branch line according to the load value;

[0057] When the load value exceeds the first threshold, a load adjustment signal is generated, and the load adjustment signal is transmitted to the corresponding branch line load control device. It should be noted that when the total electric energy transmitted by the transmission line remains substantially unchanged, the loads that can be connected to all branches under the transmission line are basically constant. In order to make the transmission line relatively stable, the sum of the electric energy obtained by the load cannot be greater than the total electric energy transmitted by the transmission line. Excluding the loss of electric energy on the transmission line, generally, the sum of the electric energy that the load can obtain cannot exceed 80% of the total electric energy transmitted by the transmission line. Therefore, the load value of the power system operating capacity of the branch line cannot exceed 80% of the total branch line electric energy that the branch line can supply.

[0058] In the above, the calculation of the load access capacity of each branch line load control device includes:

[0059] Obtaining the operating parameters of the power system of each branch line to calculate the load value of the power system operating capacity of the corresponding branch line;

[0060] Calculating a load grade set by the load level of the power system according to the load value;

[0061] Determining the output configuration margin of the power system according to the load level;

[0062] Calculate the existing access capacity of the load control equipment of each branch line according to the load level;

[0063] Calculating the access capacity margin of the load control equipment of each branch line according to the force configuration margin;

[0064] Calculate the load access capacity of each branch line load control equipment based on the existing access capacity and access capacity margin.

[0065] The operation parameters of the power system of each branch line are mainly obtained including the total power of the branch line and the power surplus that can be supplied by the branch line.

[0066] In the above, when the operating parameters of the power system of each branch line are received, it is detected whether the operating parameters of the power system of each branch line deviate and if the deviation state is within the adjustable range, the operating parameters of the power system are adjusted to the standard operating parameter range corresponding to the branch line.

[0067] In the above, the load value of the branch line power system operating capacity cannot exceed 80% of the total branch line power that the branch line can supply. At this time, the power system operating parameters of each branch line are not deviated. When it exceeds 80% of the total branch line power, it is considered that a deviation has occurred. In order to adjust the operating parameters of the power system, this application adjusts the load to a certain extent through the power system of each branch line, and the adjustable range cannot exceed 3% of the load quantity.

[0068] In the above, the load access capacity of each branch line is judged. If the sum of the load access capacity of any two branch lines is lower than the set standard threshold, the number of loads connected by the corresponding branch line load control device is adjusted so that the load access capacity of the corresponding branch lines is maintained within the set balance range. The load access balance capacity range of each branch line is determined according to the load access capacity of each branch line load control device, and the balance capacity range of a 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 safety range set after the single corresponding balance capacity range of any two branch line load control devices is adjusted according to the adjustable range according to the load access situation.

[0073] The load adjustment module adjusts 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 status of the power system.

[0074] Furthermore, the monitoring module includes:

[0075] A load level calculation module, which sets a load level according to the load level of the power system;

[0076] The output configuration margin calculation module is used to determine the output configuration margin of the power system according to the load level.

[0077] Furthermore, the monitoring module also includes:

[0078] A first trigger module is used to detect the load value of the power system operation capacity of the received branch line, and generate a load adjustment signal when the load value exceeds a first threshold value, triggering the monitoring module to obtain the operation status of the power system of each branch line;

[0079] The second trigger module is used to periodically detect the operating capacity of the power system on the main line of the transmission line according to a preset time period, and determine the upper limit value of the allocated operating state of the power system of each branch line according to the operating capacity of the power system on the main line of the transmission line;

[0080] The third trigger module is used to generate a state trigger signal of the power system when the corresponding monitoring equipment starts the monitoring of the operation status through the monitoring program of the power system, and when the operation status of the power system is unknown, to trigger the monitoring module to obtain the operation status of the power system of each branch line.

[0081] Furthermore, the load adjustment module includes:

[0082] A first load adjustment unit is used to adjust the operating parameters of the power system to within the standard operating parameter range corresponding to the branch line when the detected operating parameters of the power system deviate and the deviation state is within the adjustable range;

[0083] The second load adjustment unit is used to judge the load access capacity of each branch line. If the sum of the load access capacity 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 capacity of each corresponding branch line is maintained within the set balance range.

[0084] Furthermore, the second load adjustment unit includes: an adjustable range setting module, which is used to determine the load access balancing capacity range of each branch line according to the load access capacity of each branch line load control device, and set the balancing capacity range of a single branch line load control device to have an adjustable range set according to the load access situation.

[0085] The present invention monitors the operating status of the power system of each branch line of the transmission line in real time, thereby calculating the load access capacity of each branch line load control device according to the operating status of the power system; and 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 status of the power system. Thus, the load access capacity of each corresponding branch line is maintained within the set balance range.

[0086] In the above, the load level of the power system is the sum of the electric energy taken from the power system by the loads under the branch line corresponding to the current moment, which can be monitored and obtained by monitoring equipment installed on the branch line.

[0087] In the above. When obtaining the operating status of each branch line power system, it also 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 system of each branch line, and determining the operating status of each branch line power system according to the load value; when the load value exceeds the first threshold, a load adjustment signal is generated, and the load adjustment signal is transmitted to the corresponding branch line load control device. It should be noted that when the total electric energy transmitted by the transmission line remains substantially unchanged, the load that can be connected to all branches under the transmission line is basically constant. In order to make the transmission line in a relatively stable state, the sum of the electric energy obtained by the load cannot be greater than the total electric energy transmitted by the transmission line. Excluding the loss of electric energy on the transmission line, generally, the sum of the electric energy that the load can obtain 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 can be supplied by the branch line.

[0088] In the above, calculating the load access capacity of each branch line load management device includes: obtaining the operating parameters of the power system of each branch line to calculate the load value of the corresponding branch line power system operating capacity; calculating the load level set by the power system load level according to the load value; judging the power system output configuration margin according to the load level; calculating the existing access capacity of each branch line load management device according to the load level; calculating the access capacity margin of each branch line load management device according to the power configuration margin; calculating the load access capacity of each branch line load management device according to the existing access capacity and the access capacity margin.

[0089] The operation parameters of the power system of each branch line are mainly obtained including the total power of the branch line and the power surplus that can be supplied by the branch line.

[0090] In the above, when the operating parameters of the power system of each branch line are received, it is detected whether the operating parameters of the power system of each branch line deviate and if the deviation state is within the adjustable range, the operating parameters of the power system are adjusted to the standard operating parameter range corresponding to the branch line.

[0091] In the above, the load value of the branch line power system operating capacity cannot exceed 80% of the total branch line power that the branch line can supply. At this time, the power system operating parameters of each branch line are not deviated. When it exceeds 80% of the total branch line power, it is considered that a deviation has occurred. In order to adjust the operating parameters of the power system, this application adjusts the load to a certain extent through the power system of each branch line, and the adjustable range cannot exceed 3% of the load quantity.
