Description

Technical Field

[0001] The present application relates to the technical field of power distribution networks, and in particular to a method and device for processing a load. Background Art

[0002] In recent years, power grid automation technology has developed rapidly, and automated switches are widely used in distribution network load transfer, programmed operation, remote rapid operation and power restoration, etc. In the operation of the power grid, it is often necessary to transfer the load of the 10kV medium voltage part from station A to stations B, C, D... for power supply, or from bus a to bus b, c, d... for power supply due to main network equipment failure (such as main transformer failure, 110kV bus, 110kV line, etc.) or section load limitation. For example, Figure 1 It is a schematic diagram of bus load transfer provided by the prior art, such as Figure 1 As shown, the load of 10 kV aM (ie, 10 kV a bus) can be transferred to 10 kV bM (ie, 10 kV b bus) and / or 10 kV cM (ie, 10 kV c bus).

[0003] Moreover, in the related technologies, it is generally necessary to manually judge whether the substation or busbar is under pressure based on the information sent by the substation and feeder automation switch, and then manually analyze the switches to be operated according to the connection relationship of the power grid topology, and check whether the 10kV line, busbar, 110kV line and other equipment on the opposite side will be overloaded after the transfer, and then perform manual remote control operations to transfer the load. However, the analysis process in the related technologies requires a lot of manual analysis and manual remote control operations, which puts high demands on the technical requirements and operational proficiency of the dispatching and operating personnel. Especially when the power grid fails, this has a great impact on the power supply reliability of the power supply area. The fault needs to be handled quickly, and it is completely dependent on manual handling. It is no longer suitable for social development. It is urgent to realize rapid regional load rapid transfer and rapid power restoration to improve regional power supply reliability.

[0004] In addition, the key process of judging whether the power grid equipment is in a faulty state and whether it is necessary to start batch transfer of loads in the relevant technology still requires human participation in the judgment to prevent the false start or missed start of the "batch transfer of loads" process. However, this has a great impact on the rapid batch transfer processing of power grid faults, which will delay the load transfer speed and reduce the power supply reliability.

[0005] Currently, no effective solution has been proposed to the problem that in the related art, whether it is necessary to transfer the power load on the distribution network line is determined manually, resulting in slow judgment and load transfer, and further leading to poor reliability of power supply using the distribution network.

[0035] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0036] Batch load transfer: refers to a technology that uses automated equipment or systems to cooperate with each other to achieve rapid transfer of power loads on distribution lines due to problems such as power grid equipment failure, section overload, and power grid risk.

[0037] The present invention is described below in conjunction with preferred implementation steps. Figure 2 is a flow chart of a load processing method provided in an embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0038] Step S201, obtaining telemetry information of a substation in a distribution network, and determining voltage values ​​of a plurality of buses corresponding to the substation in the distribution network based on the telemetry information of the substation in the distribution network.

[0039] For example, the 10kV bus voltage values ​​of all substations, the three-phase current values ​​of all substation transformer lowering switches, and the three-phase current values ​​of all 10kV outgoing line switches can be used as monitoring object points, and the telemetry values ​​of the monitoring object points can be obtained, and the telemetry values ​​of the monitoring object points (corresponding to the above-mentioned telemetry information) can include the voltage value of the 10kV bus (corresponding to the voltage values ​​of the above-mentioned multiple buses), the three-phase current value of the transformer lowering switch, and the three-phase current value of the 10kV outgoing line switch.

[0040] Step S202, according to the telemetry information of the substation in the distribution network, obtain the three-phase current value of each low-voltage switch in the substation in the distribution network, wherein each low-voltage switch is used to adjust the voltage output by the substation in the distribution network.

[0041] For example, the telemetry value (corresponding to the telemetry information mentioned above) may include the three-phase current value of the variable-lower switch (corresponding to the three-phase current value of each variable-lower switch mentioned above).

[0042] Step S203, obtaining the three-phase current value of each outgoing switch in the distribution network according to the telemetry information of the substation in the distribution network, wherein each outgoing switch is an outgoing switch connected to each bus corresponding to the substation in the distribution network.

[0043] For example, the telemetry value (corresponding to the telemetry information mentioned above) may include the three-phase current value of the 10 kV outgoing line switch (corresponding to the three-phase current value of each outgoing line switch mentioned above).

[0044] Step S204, based on the voltage values ​​of the multiple busbars, the three-phase current value of each low-voltage switch and the three-phase current value of each outgoing switch, determine the detection results of the multiple busbars, wherein the detection results are used to indicate whether it is necessary to transfer the power load on the multiple busbars.

[0045] For example, it is possible to automatically determine whether it is necessary to transfer the power load on the distribution network lines based on the voltage value of the 10kV bus (corresponding to the voltage values ​​of the multiple busbars mentioned above), the three-phase current value of the step-down switch (corresponding to the three-phase current value of each step-down switch mentioned above) and the three-phase current value of the 10kV outgoing switch (corresponding to the three-phase current value of each outgoing switch mentioned above).

[0046] Through the above-mentioned steps S201 to S204, the voltage values ​​of multiple busbars corresponding to the substation in the distribution network are determined based on the telemetry information of the substation in the distribution network, and the three-phase current value of each transformer substation in the distribution network and the three-phase current value of each outgoing switch in the distribution network are obtained. Then, according to the voltage values ​​of the multiple busbars, the three-phase current value of each transformer substation and the three-phase current value of each outgoing switch, it is determined whether it is necessary to transfer the power load on the multiple busbars, so that it can automatically determine whether it is necessary to transfer the power load on the line of the distribution network without manual intervention, thereby improving the speed of determining whether to transfer the load and the speed of transferring the load, thereby achieving the effect of improving the reliability of power supply of the distribution network.

[0047] Optionally, in the load processing method provided in the embodiment of the present application, based on the voltage values ​​of multiple busbars, the three-phase current value of each transformer lowering switch and the three-phase current value of each outgoing line switch, the detection results of multiple busbars are determined, including: based on the voltage values ​​of multiple busbars, the initial voltage value of each busbar corresponding to the substation in the distribution network is determined; the latest voltage value of each busbar corresponding to the substation in the distribution network is obtained; it is judged whether the latest voltage value of each busbar is the same as the initial voltage value of each busbar, and whether the latest voltage value of each busbar is less than a first preset value, to obtain a judgment result; based on the judgment result, the three-phase current value of each transformer lowering switch and the three-phase current value of each outgoing line switch, the detection results of multiple busbars are determined.

[0048] For example, the signal-free collection period T can be set to 30 seconds (settable); the maximum signal collection period Tmax can be set to 100 seconds (settable); the busbar voltage loss threshold can be set to 30% (settable); the telemetry section refresh period Ts can be set to 5 seconds (settable); and the 10kV busbar voltage values ​​of all substations, the three-phase current values ​​of all substation transformer lowering switches, and the three-phase current values ​​of all 10kV outgoing line switches can be used as monitoring object points; then the telemetry values ​​of the monitoring object points (corresponding to the above-mentioned telemetry information, that is, the voltage value of the 10kV busbar, the three-phase current value of the transformer lowering switch, and the three-phase current value of the 10kV outgoing line switch) can be maintained. It exists in the cache area; then read the latest values ​​of all monitored object points (10kV bus voltage) (corresponding to the latest voltage value of each bus mentioned above), compare the voltage value in the cache area (corresponding to the initial voltage value of each bus mentioned above), whether there is a change and the latest value is less than 30% of the rated value (corresponding to the first preset value mentioned above), and according to the comparison result (corresponding to the above judgment result), the three-phase current value of the low-voltage switch (corresponding to the three-phase current value of each low-voltage switch mentioned above) and the three-phase current value of the 10kV outgoing line switch (corresponding to the three-phase current value of each outgoing line switch mentioned above), judge whether it is necessary to transfer the power load on the line of the distribution network.

[0049] In summary, by comparing the latest bus voltage value with the bus voltage value stored in the buffer area, it can be quickly and accurately determined whether the power load on the line of the distribution network needs to be transferred.

[0050] Optionally, in the load processing method provided in the embodiment of the present application, based on the judgment result, the three-phase current value of each transformer and the three-phase current value of each outgoing switch, the detection results of multiple busbars are determined, including: if the judgment result indicates that the latest voltage value of each busbar is the same as the initial voltage value of each busbar, and / or the latest voltage value of each busbar is not less than a first preset value, then the detection result is determined to be that there is no need to transfer the power loads on multiple busbars; if the judgment result indicates that the latest voltage value of at least one busbar is different from the initial voltage value, and the latest voltage value of at least one busbar is less than the first preset value, then the identification information of at least one busbar is obtained; based on the identification information of at least one busbar, the three-phase current value of each transformer and the three-phase current value of each outgoing switch, the detection results of multiple busbars are determined.

[0052] In summary, by comparing the latest voltage value of the bus with the bus voltage value stored in the cache, the voltage jump bus can be quickly and accurately determined, and the identification information of the device connected to the voltage jump bus can be easily obtained.

[0053] Optionally, in the load processing method provided in the embodiment of the present application, based on the identification information of at least one bus, the three-phase current value of each transformer and the three-phase current value of each outgoing switch, determining the detection results of multiple busbars includes: based on the identification information of at least one bus, determining the status information of the target device corresponding to at least one bus, wherein the target device includes at least one of the following: a transformer and a target line connected to at least one bus, and a substation corresponding to at least one bus; judging whether the target device corresponding to at least one bus is in a target state, wherein the target state includes at least one of the following: a maintenance state, a debugging state, a setting state and a blocking state; if the target device corresponding to at least one bus is in the target state, determining the detection result is that there is no need to transfer the power loads on multiple buses; if the target device corresponding to at least one bus is not in the target state, determining the detection results of multiple buses based on the three-phase current value of each transformer and the three-phase current value of each outgoing switch.

[0057] For example, if the main transformer, 110kV bus, 110kV line, 220kV line, 220kV bus and corresponding substation and other equipment (corresponding to the above-mentioned target equipment) connected to the voltage jump bus (corresponding to at least one of the above-mentioned buses) do not have signs such as "maintenance" or "debugging" or "setting" or "data blocking" (corresponding to the above-mentioned identification information), then all substation 10kV bus voltage values, all substation low-voltage switches' three-phase current values ​​and all 10kV outgoing line switches' three-phase current values ​​in the buffer area can be stored in the waiting area; and start collecting and recording the substation All alarm signals and telemetry information in the power station are collected until the signal-to-signal interval time is greater than the collection period T, or the collection period time is greater than or equal to the maximum signal collection period Tmax, and the signal collection is terminated; then, the three-phase current of the variable-voltage switch corresponding to the collected voltage jump bus (corresponding to the target three-phase current value of the variable-voltage switch corresponding to at least one of the above-mentioned buses) and the three-phase current of the outgoing switch connected to the voltage jump bus (corresponding to the target three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses) can be used to determine whether it is necessary to transfer the power load on the distribution network line.

[0058] Through the above scheme, the three-phase current of the lowering switch corresponding to the voltage jump bus and the three-phase current of the outgoing switch connected to the voltage jump bus can be easily collected.

[0059] Optionally, in the load processing method provided in the embodiment of the present application, based on the target three-phase current value of the transformer corresponding to at least one bus and the target three-phase current value of the outgoing switch connected to at least one bus, determining the detection results of multiple busbars includes: obtaining the latest three-phase current value of the transformer corresponding to at least one bus, and judging whether the latest three-phase current value of the transformer corresponding to at least one bus is the same as the target three-phase current value of the transformer corresponding to at least one bus, and whether the latest three-phase current value of the transformer corresponding to at least one bus is less than a second preset value; if the latest three-phase current value of the transformer corresponding to at least one bus is less than a second preset value, then the target three-phase current value of the transformer corresponding to at least one bus is determined; If the new three-phase current value is the same as the target three-phase current value of the transformer lowering switch corresponding to at least one bus, and / or the latest three-phase current value of the transformer lowering switch corresponding to at least one bus is not less than the second preset value, the detection result is determined to be that there is no need to transfer the power load on multiple busbars; if the latest three-phase current value of the transformer lowering switch corresponding to at least one bus is different from the target three-phase current value of the transformer lowering switch corresponding to at least one bus, and the latest three-phase current value of the transformer lowering switch corresponding to at least one bus is less than the second preset value, the detection results of multiple buses are determined based on the target three-phase current value of the outgoing switch connected to at least one bus.

[0060] For example, find the three-phase current of the voltage-changing switch corresponding to the voltage jump bus, compare the latest three-phase current value of the voltage-changing switch (corresponding to the latest three-phase current value of the voltage-changing switch corresponding to at least one of the above-mentioned buses) with the current value in the area to be processed (corresponding to the target three-phase current value of the voltage-changing switch corresponding to at least one of the above-mentioned buses), and check whether there is any change and whether the latest value is less than 1A (corresponding to the second preset value mentioned above); if the latest three-phase current value of the voltage-changing switch (corresponding to the latest three-phase current value of the voltage-changing switch corresponding to at least one of the above-mentioned buses) and the current value in the area to be processed (corresponding to the target three-phase current value of the voltage-changing switch corresponding to at least one of the above-mentioned buses) have no change, and / or the latest value (corresponding to the latest three-phase current value of the voltage-changing switch corresponding to at least one of the above-mentioned buses) has no change. ) is not less than 1A (corresponding to the above-mentioned second preset value), there is no need to transfer the power load on the lines of the distribution network; if the latest three-phase current value of the transformer lowering switch (corresponding to the latest three-phase current value of the transformer lowering switch corresponding to at least one of the above-mentioned buses) and the current value in the to-be-processed area (corresponding to the target three-phase current value of the transformer lowering switch corresponding to at least one of the above-mentioned buses) has changed and the latest value (corresponding to the latest three-phase current value of the transformer lowering switch corresponding to at least one of the above-mentioned buses) is less than 1A (corresponding to the above-mentioned second preset value), then according to the three-phase current of the outgoing switch connected to the voltage jump bus (corresponding to the target three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses), it is determined whether it is necessary to transfer the power load on the lines of the distribution network.

[0061] Through the above scheme, according to the three-phase current of the voltage-changing switch corresponding to the voltage jump bus, it can be quickly and accurately determined whether the power load on the line of the distribution network needs to be transferred.

[0062] Optionally, in the load processing method provided in the embodiment of the present application, determining the detection results of multiple busbars based on the target three-phase current value of the outgoing switch connected to at least one busbar includes: obtaining the latest three-phase current value of the outgoing switch connected to at least one busbar, and judging whether the latest three-phase current value of the outgoing switch connected to at least one busbar is the same as the target three-phase current value of the outgoing switch connected to at least one busbar, and whether the latest three-phase current value of the outgoing switch connected to at least one busbar is less than a third preset value; if the latest three-phase current value of the outgoing switch connected to at least one busbar is less than a third preset value, If the three-phase current value is the same as the target three-phase current value of the outgoing switch connected to at least one bus, and / or the latest three-phase current value of the outgoing switch connected to at least one bus is not less than the third preset value, then the detection result is determined to be that there is no need to transfer the power load on the multiple busbars; if the latest three-phase current value of the outgoing switch connected to at least one bus is different from the target three-phase current value of the outgoing switch connected to at least one bus, and the latest three-phase current value of the outgoing switch connected to at least one bus is less than the third preset value, then the detection result is determined to be that the power load on at least one bus needs to be transferred.

[0063] For example, if the latest three-phase current value of the variable-voltage switch (corresponding to the latest three-phase current value of the variable-voltage switch corresponding to at least one of the above-mentioned buses) is different from the current value in the to-be-processed area (corresponding to the target three-phase current value of the variable-voltage switch corresponding to at least one of the above-mentioned buses) and the latest value (corresponding to the latest three-phase current value of the variable-voltage switch corresponding to at least one of the above-mentioned buses) is less than 1A (corresponding to the second preset value mentioned above), then the three-phase current of the outgoing switch connected to the voltage jump bus is found, and the latest three-phase current value of the outgoing switch (corresponding to the latest three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses) is compared with the current value in the to-be-processed area (corresponding to the target three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses), to see if there is a change and whether the latest value is less than 1A (corresponding to the third preset value mentioned above); if the latest three-phase current value of the outgoing switch (corresponding to the latest three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses) is different from the current value in the to-be-processed area If the current value (corresponding to the target three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses) does not change, and / or the latest value (corresponding to the latest three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses) is not less than 1A (corresponding to the third preset value mentioned above), there is no need to transfer the power load on the line of the distribution network; if the latest three-phase current value of the outgoing switch (corresponding to the latest three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses) and the current value in the to-be-processed area (corresponding to the target three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses) change and the latest value (corresponding to the latest three-phase current value of the outgoing switch connected to at least one of the above-mentioned buses) is less than 1A (corresponding to the third preset value mentioned above), it is necessary to transfer the power load on the line of the distribution network, locate the voltage jump bus as the target bus for the required batch load transfer, start the batch transfer processing process, and complete all fault start-up judgment processes.

[0064] Through the above scheme, it is possible to quickly and accurately determine whether it is necessary to transfer the power load on the line of the distribution network according to the three-phase current of the outgoing switch connected to the voltage jump bus.

[0065] For example, this embodiment proposes "a method for starting load batch transfer control", which enables the system to automatically determine the fault status of the power grid and automatically start batch transfer analysis to increase the batch transfer speed in the above situation and improve regional power supply reliability.

[0066] Moreover, this embodiment is aimed at the key process of starting batch load transfer, most of which requires manual participation in judgment to prevent the problem of false start or missed start. Through this embodiment, the manual judgment to start the "batch load transfer" function is transformed into automatic system judgment, and the expert experience is systematized to improve the accuracy and timeliness of judgment, so as to increase the speed of batch transfer in the event of power grid equipment failure, improve regional power supply reliability, shorten power outage time, and reduce the impact of power grid equipment failure.

[0067] In addition, the loss of voltage in the local substation and busbar is not necessarily caused by equipment failure at the local station, for example, Figure 3 is a schematic diagram of the substation transmission line in this embodiment, such as Figure 3 As shown, if the L2 line fails and the substation ST3 is powered by the transmission line L2, there will be no equipment protection action signal for ST3 in the substation. Therefore, the diagnosis of substation pressure loss and busbar pressure loss failure is mainly based on the change of telemetry status, combined with some pressure loss signals in the substation as a comprehensive auxiliary judgment, and the substation pressure loss is inferred. After diagnosing the pressure loss, the "load batch transfer control" function is activated to complete the subsequent load batch transfer and realize rapid power restoration. And Figure 3 KG1, KG2, KG3, KG4, KG5 and KG6 in the figure all represent switches in the circuit. Figure 3 ST1, ST2, ST3 and ST4 in the figure all represent substations. Figure 3 L1, L2 and L3 in the figure all represent power supply lines.

[0068] For example, Figure 4 is a flow chart of a method for starting a load batch transfer control according to an embodiment of the present application. Figure 4 As shown, the load batch transfer control startup method includes the following steps:

[0069] Step 1: Set the no-signal collection period T = 30 seconds (settable); set the maximum signal collection period Tmax = 100 seconds (settable); set the busbar voltage loss threshold to 30% (settable); set the telemetry section refresh period Ts = 5 seconds (settable); take the 10kV busbar voltage values ​​of all substations, the three-phase current values ​​of all substation transformer switches, and the three-phase current values ​​of all 10kV outgoing line switches as monitoring object points;

[0070] Step 2: Save the telemetry value of the monitored object point in the buffer area, refresh the buffer area in the next cycle, and jump to step 3;

[0071] Step 3: Obtain the electrical relationship of 110kV / 220kV lines, busbars, and main transformers from the automation master station system, and search for the 10kV busbars corresponding to the above equipment and the corresponding main transformer low-voltage switches according to the electrical connection relationship; search for the 10kV outgoing line switches connected to the 10kV busbars, form a switch list, and jump to step 4;

[0072] Step 4: Read the latest values ​​of all monitoring object points (10kV bus voltage), compare the voltage values ​​in the buffer area, and check whether there is any change and whether the latest value is less than 30% of the rated value. If yes, record the changed bus ID (Identification), the voltage value before and after the jump, and jump to step 5 for judgment; if no, delay Ts and jump to step 2 for the next collection value comparison;

[0073] Step 5: Find the main transformer, 110kV bus, 110kV line, 220kV line, 220kV bus and corresponding substation connected to the voltage jump bus, and check whether the above equipment has signs such as "maintenance", "debugging", "setting numbers", and "data blocking"; if so, after Ts delay, jump to step 2 for collection; if not, jump to step 6 for processing;

[0074] Step 6: Store all 10kV bus voltage values ​​of the substations in the buffer area, the three-phase current values ​​of all substation transformer switches, and the three-phase current values ​​of all 10kV outgoing line switches in the waiting area; and start collecting and recording all alarm signals and telemetry information in the substation until the interval between signals is greater than the collection cycle T, or the collection cycle time is greater than or equal to the maximum signal collection cycle Tmax, end signal collection, and jump to step 7 to start processing;

[0075] Step 7: Find the three-phase current of the low-voltage switch corresponding to the voltage jump bus, compare the latest three-phase current value of the low-voltage switch with the current value in the area to be processed, and check whether there is any change and whether the latest value is less than 1A. If yes, jump to step 8. If not, after Ts delay, jump to step 2 for collection;

[0076] Step 8: Find the three-phase current of the outgoing switch connected to the voltage jump bus, compare the latest three-phase current value of the outgoing switch with the current value in the area to be processed, and check whether there is any change and whether the latest value is less than 1A. If yes, jump to step 9; if not, after Ts delay, jump to step 2 for collection;

[0077] Step 9: Locate the voltage jump bus as the target bus for the required batch load transfer, and start the batch transfer process;

[0078] At this point, the entire fault startup judgment process is completed.

[0079] Therefore, through this embodiment, the computer system can be used to realize the judgment of the start-up of the batch transfer control of the pressure loss fault load, thereby improving the reliability of the power supply of the power grid. Moreover, compared with the past, this embodiment can only confirm whether it is necessary to start the batch pressure loss transfer processing flow by manual judgment, but the manual judgment processing speed is slow and the reliability is poor. In view of the problem that requires manual judgment and start-up, this embodiment systematizes the expert judgment experience through the extraction and judgment of system data, realizes the automatic judgment and start-up of the batch pressure loss transfer start-up, and improves the reliability of the power supply of the power grid.

[0080] At the same time, in addition to being completely implemented by computer without manual intervention, the batch transfer control of pressure loss fault loads can be started very quickly, greatly reducing the power outage time caused by power grid faults and maximizing the power supply reliability of the regional power grid.
