Description

[0002] In order to ensure that electrical equipment operates within the rated load and avoid damage to the electrical equipment caused by overload, after measures such as orderly power consumption are ineffective, it is often necessary to adopt means such as forced peak shaving on the dispatching side, disconnect corresponding lines and main transformer switches, control the power consumption load, and ensure the normal operation of the electrical equipment.

[0003] The current technical means for carrying out forced peak shaving work on dispatching lines have the following deficiencies: In the execution link, the dispatcher needs to manually search and screen according to the lines and sequence positions given in the screening and searching links, and then enter the automation system to operate each switch one by one. The whole process takes at least more than 10 minutes, which may cause damage to the electrical equipment and further affect the safe operation of the power grid; on the other hand, the dispatcher needs to manually cut off one by one, and each cut-off includes steps such as selecting a substation, selecting equipment, entering the remote control page, entering the remote control password, entering the supervision password, and executing the remote control, which consumes a lot of time. At the same time, the remote control password and the supervision password need to be entered by two dispatchers respectively.

[0044] Embodiment 1

[0045] Figure 1 A flowchart of a method for controlling a power grid electrical switch cluster is provided for Embodiment 1 of the present invention. This embodiment is applicable to the situation of controlling a fast electrical switch cluster for power grid peak shaving and load shedding. The method for controlling the power grid electrical switch cluster can be executed by a power grid electrical switch cluster control device. The power grid electrical switch cluster control device can be implemented in the form of hardware and / or software, and can be configured in an electronic device of the power grid. As Figure 1 shown, the method for controlling the power grid electrical switch cluster includes:

[0046] S110. Obtain the line attributes of each line in the initial sequence table of the OCS system, and screen each line in the initial sequence table according to the line attributes to generate a selected line sample sequence table.

[0047] Among them, the OCS system is the main distribution integrated dispatching automation system applied to the power grid. The OCS system can include, but is not limited to, power grid power flow data, topology data, and sequence tables, and is stored in the database of the OCS system.

[0048] The initial sequence table contains the line attributes, power flow data, topology data, and other line-related data of each line. This embodiment does not impose any restrictions on the specific data information and existence form of the initial sequence table.

[0049] In this embodiment, the line attributes of each line can be used as conditions for subsequent screening of the line. The line attributes of each line include line name, real-time load value, region and substation. It can be understood that each line attribute can be used as a screening condition for the line.

[0050] Specifically, at least one of the line name, real-time load value, region and substation included in the line attributes is used as a line screening condition, and each line in the initial ranking table is screened based on the line screening condition.

[0051] It can be understood that the line attributes including the line name, real-time load value, region and substation can be selected as line screening conditions for the current line before being used as line screening conditions. Specifically, if all line attributes of each line are not selected, all line attributes use default values. Optionally, the default value is the full set, that is, all line attributes of each line remain unchanged, no screening is performed, and the line attributes of all lines are retained in the initial sequence table. At this time, the initial sequence table is equivalent to the sample sequence table of the selected line.

[0052] On the basis of the above, at least one of the line name, real-time load value, region and substation included in the line attributes is used as a line screening condition, including: judging in turn whether the line name, real-time load value, region and substation included in the line attributes are selected as line screening conditions; and screening each line in the initial sequence table according to the result of judging whether they are selected as line screening conditions.

[0053] Exemplarily, it is determined whether the line name is selected as the line screening condition, whether the real-time load value is selected as the line screening condition, whether the region to which it belongs is selected as the line screening condition, or whether the substation to which it belongs is selected as the line screening condition. Each line in the initial ranking table can be screened based on the above judgment results.

[0054] According to the order of power restriction execution, since different load type lines have different priorities when executing power restriction, in this embodiment, the line attributes also include load types, and the load types include high-energy-consuming users, pure industrial users, and mixed users. Then the priority when executing power restriction is high-energy-consuming users, pure industrial users, and mixed users.

[0055] On the basis of the above, before generating the selected line sample ranking table, it also includes: using high energy consumption users, pure industrial users and mixed users as screening conditions to screen each line in the initial ranking table.

[0056] Specifically, the selected line sample sequence table is obtained after screening with high-energy-consuming users, pure industrial users, and mixed users as screening conditions, and at least one of the line name, real-time load value, affiliated region, and affiliated substation included in the line attributes is used as a line screening condition for screening.

[0057] S120. Determine the cumulative real-time load value of the selected line based on the selected line sample sequence table. If the cumulative real-time load value is greater than or equal to the set load shedding limit value, then use the selected line as the line to be controlled.

[0058] Exemplarily, taking the selected line sample sequence table obtained by screening with high-energy-consuming users, pure industrial users, and mixed users as screening conditions as an example, use the lines corresponding to high-energy-consuming users, pure industrial users, and mixed users as the selected lines for subsequent operations respectively.

[0059] Specifically, use the line corresponding to the high-energy-consuming user as the selected line, obtain the cumulative real-time load value of the line corresponding to the high-energy-consuming user, and determine whether the line corresponding to the high-energy-consuming user is the line to be controlled according to the cumulative real-time load value of the line corresponding to the high-energy-consuming user; similarly, use the line corresponding to the pure industrial user as the selected line, obtain the cumulative real-time load value of the line corresponding to the pure industrial user, and determine whether the line corresponding to the pure industrial user is the line to be controlled according to the cumulative real-time load value of the line corresponding to the pure industrial user; similarly, use the line corresponding to the mixed user as the selected line, obtain the cumulative real-time load value of the line corresponding to the mixed user, and determine whether the line corresponding to the mixed user is the line to be controlled according to the cumulative real-time load value of the line corresponding to the mixed user.

[0060] It should be noted that here, the selected line can be one, two, multiple, or all of the lines corresponding to the high-energy-consuming users. Similarly, the selected line can be one, two, multiple, or all of the lines corresponding to the pure industrial users. The selected line can be one, two, multiple, or all of the lines corresponding to the mixed users. This embodiment does not impose any restrictions on this.

[0061] On this basis, if the cumulative real-time load value is less than the set load shedding limit value, then determine the updated line and the corresponding cumulative load value of the updated line based on the selected line sample sequence table; judge whether to control the updated line to be in the closed state according to the cumulative load value of the updated line and the set load shedding limit value.

[0062] It can be understood that the updated lines here are to adjust the number of lines included in the selected lines. For example, when the selected lines are two of the lines corresponding to high-energy-consuming users, at this time, the real-time load accumulation value of the two lines corresponding to the high-energy-consuming users is less than the set power-limiting load value, then more lines corresponding to high-energy-consuming users can be selected as updated lines, and the load calculation is performed again, and then all lines corresponding to high-energy-consuming users are traversed.

[0063] Furthermore, it can be known that the real-time load accumulation value of the selected line is determined based on the selected line sample ranking table, and then whether the selected line is a line to be controlled is determined. Therefore, all lines in the selected line sample ranking table need to be traversed according to the line screening conditions.

[0064] After traversing each line in the initial sequence table, the screening is stopped. If each line in the initial sequence table is not traversed, each line in the initial sequence table is screened again according to the line attribute.

[0065] S130: Control the electrical switch cluster corresponding to the line to be controlled to be in a closed state to cut off the line to be controlled in the power grid.

[0066] Among them, the line to be controlled is a line that needs to perform power-limiting operation. To perform power-limiting operation, it is necessary to control the electrical switch cluster corresponding to the line to be controlled, that is, control the electrical switch cluster corresponding to the line to be controlled to be in a closed state to cut off the line to be controlled in the power grid.

[0067] Based on the above embodiment, if the accumulated real-time load values ​​of all lines corresponding to each line attribute in the initial ranking table are greater than or equal to the set power-limiting load value, the electrical switch clusters corresponding to all lines corresponding to each line attribute are closed.

[0068] Exemplarily, on the above basis, after selecting the line corresponding to the high-energy-consuming user as the selected line, first, determine whether the cumulative value of the real-time loads of all the lines corresponding to the selected high-energy-consuming user is greater than or equal to the set load-shedding load value. If so, then control the electrical switch cluster corresponding to all the lines of the high-energy-consuming user to be in the off state. If not, then continue to select the lines corresponding to the high-energy-consuming user to determine whether they are the lines to be controlled; similarly, after selecting the line corresponding to the pure industrial user as the selected line, first, determine whether the cumulative value of the real-time loads of all the lines corresponding to the selected pure industrial user is greater than or equal to the set load-shedding load value. If so, then control the electrical switch cluster corresponding to all the lines of the pure industrial user to be in the off state. If not, then continue to select the lines corresponding to the pure industrial user to determine whether they are the lines to be controlled; similarly, after selecting the line corresponding to the mixed user as the selected line, first, determine whether the cumulative value of the real-time loads of all the lines corresponding to the selected mixed user is greater than or equal to the set load-shedding load value. If so, then control the electrical switch cluster corresponding to all the lines of the mixed user to be in the off state. If not, then continue to select the lines corresponding to the mixed user to determine whether they are the lines to be controlled.

[0069] In this embodiment, after determining the line to be controlled, the control request of the line to be controlled is fed back to the remote dispatcher. After the dispatcher inputs the remote control password and the supervision password respectively, the remote control operation of the electrical switch cluster corresponding to the line to be controlled is performed in parallel, that is, the electrical switch cluster corresponding to the line to be controlled is controlled to be in the off state to cut off the line to be controlled in the power grid, to cut off the load corresponding to the line to be controlled, and at the same time, the execution status of the real-time electrical switch cluster of the line to be controlled can also be fed back.

[0070] At present, the steps of forced peak-shaving and load-shedding of lines are divided into two links: screening and execution. The original operation process of the screening link is manual line screening -> manual searching and cumulative screening of line loads until the load-shedding load requirement is met. The technical solution of this embodiment can automatically screen and give the lines that need to perform load-shedding, without manual intervention, and the screened data can be directly transmitted to the execution link, saving the time of manually searching for equipment one by one. At the same time, this application adopts the electrical switch group control technology, saving the manpower and time of inputting passwords multiple times. Through the input of a single remote control password and supervision password, the remote control operation of the electrical switch is performed in parallel, and the manpower and time costs are at least reduced to 1 / N of the original, and the efficiency is at least increased by N times - N is the number of screened lines - and the forced peak-shaving and load-shedding can be completed as required within 1 minute, thus meeting the timeliness requirements of the load-shedding operation.

[0071] The technical solution of the embodiment of the present invention is to obtain the line attributes of each line in the initial sequence table of the OCS system, and screen each line in the initial sequence table according to the line attributes to generate a selected line sample sequence table; determine the cumulative real-time load of the selected lines based on the selected line sample sequence table. If the cumulative real-time load is greater than or equal to the set load shedding value, the selected line is used as the line to be controlled; control the electrical switch cluster corresponding to the line to be controlled to be in the off state to cut off the line to be controlled in the power grid. The present invention solves the problems that the current power grid line scheduling is time-consuming and costly, and at the same time, the scheduling speed is slow, which may cause losses to electrical equipment and then affect the safe operation of the power grid. It realizes increasing the control execution speed of the electrical switch cluster in the power grid, improving the control efficiency, controlling the load of electrical equipment, and thus ensuring the normal operation of the electrical equipment in the power grid.
