[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0045] Figure 1 A flowchart of a method for processing busbar pressure loss is provided in an embodiment of the present invention. This embodiment can be applied to processing the situation of busbar pressure loss in a distribution network. The method can be executed by a processing device for busbar pressure loss. The processing device for busbar pressure loss can be implemented in the form of hardware and / or software. The processing device for busbar pressure loss can be configured in a busbar pressure loss processing device.

[0046] refer to Figure 1 , the method comprises the following steps:

[0047] S110. Obtain the status of each bus in the distribution network.

[0048] The busbars in the distribution network may include a busbar with a voltage of 10 kV, and the state of the busbars in the distribution network may include the busbar in the distribution network being in a voltage-losing state.

[0049] It should be noted that the embodiment of the present invention continuously monitors the operation status and real-time data of the distribution network. When the following conditions are met, it can be determined that the bus in the distribution network is in a de-voltage state: the line voltage of a bus in the distribution network is lower than the first set voltage value, and the bus tie switch connected to the bus starts the fault protection action (including backup automatic transfer action, reclosing action, etc.), and the duration is greater than the system parameter setting value, and the bus is in a non-maintenance state, then it is judged as a de-voltage bus.

[0050] For example, a busbar in a de-voltage state may have a line voltage lower than 0.05 kV and maintain for 15 seconds, and a busbar in a maintenance state (lowering switch and bus tie switch are connected to the station debugging sign or maintenance sign) is excluded. The same busbar de-voltage event is only handled once within 2 minutes.

[0051] S120: When it is detected that a busbar in the distribution network is in a voltage-loss state, a busbar voltage-loss event list is refreshed.

[0052] It should be noted that when it is detected that a bus in the distribution network is in a de-voltage state, the bus de-voltage event list refreshes the bus de-voltage event information, which may include the bus de-voltage time, bus de-voltage event description, bus de-voltage event type, and bus de-voltage execution status. If the program of the bus de-voltage event list is in a closed state, the program will be automatically opened and the bus de-voltage event list will be refreshed. If the program is already opened, the bus de-voltage event list will be refreshed directly. After the distribution network dispatcher selects a bus de-voltage event for processing, the event list will simultaneously refresh the bus de-voltage execution status, bus de-voltage processing node, and bus de-voltage processor, and simultaneously prohibit other nodes or other processors from processing the bus de-voltage event. The distribution network dispatcher can close the processing window by selecting the time being processed and clicking the cancel processing button, and the bus de-voltage execution status will be restored to unprocessed.

[0053] S130. Generate a busbar pressure loss self-healing plan according to the busbar pressure loss event list, and start a busbar pressure loss self-healing interface to list the busbar pressure loss self-healing plans.

[0054] It is understandable that when the bus is determined to be in a depressurized state, according to the bus depressurization event list, for the self-healing lines that have been put into operation, the bus depressurization self-healing plan can be generated based on the comprehensive line connection topology, the controllability of the interconnecting switch, the load rate of the opposite line / main transformer (based on the section of the line before depressurization on this side and the real-time section of the opposite line) and other conditions. At the same time, the bus depressurization self-healing interface is started to list the bus depressurization self-healing plans, and the plan can be modified and the corresponding execution operations can be performed. After the bus depressurization event is analyzed, according to the real-time operation status of the distribution network and whether it involves important users, etc., some plans with abnormal operation data are shielded, and the transfer plans of all affected depressurized buses are listed in the established priority order.

[0055] S140: Execute the selected busbar voltage loss self-healing solution to restore power to the busbar.

[0056] The solution of the embodiment of the present invention can realize automatic perception, emergency handling, rapid power restoration of automated coverage lines, and auxiliary decision-making for non-automated coverage lines for large-scale power outages such as more than a dozen communities or multiple substations. It greatly reduces the input of manpower and material resources for distribution network dispatching and emergency repair, shortens the power outage time, helps to ensure more stable and safe operation of the distribution network, and improves the emergency power restoration capability.

[0057] Figure 2 A flowchart of another method for processing busbar pressure loss provided by an embodiment of the present invention, referring to Figure 2 , the method comprises the following steps:

[0058] S210. Obtain the status of each bus in the distribution network.

[0059] S220: When it is detected that a busbar in the distribution network is in a voltage-loss state, a busbar voltage-loss event list is refreshed.

[0060] S230. Generate a busbar pressure loss self-healing plan according to the busbar pressure loss event list, and start a busbar pressure loss self-healing interface to list the busbar pressure loss self-healing plan.

[0061] S240: Execute the selected busbar voltage loss self-healing solution to restore power to the busbar.

[0062] Optionally, based on the above embodiment, step S210 includes: obtaining the status of each bus in the plant diagram of the distribution network; when it is detected that the bus triggers the self-healing simulation mode in the plant diagram, it is determined that the bus is in a voltage-depleted state; wherein the self-healing simulation mode includes selecting simulated bus self-healing in the menu after the bus is clicked.

[0063] Exemplarily, the busbar triggered self-healing simulation mode exists in the plant diagram, including that after a busbar in the plant diagram of the distribution network is right-clicked, simulated busbar self-healing is selected in the menu.

[0064] The embodiment of the present invention obtains the status of each bus in the plant diagram of the distribution network, and when it is detected that the bus in the plant diagram triggers the self-healing simulation mode, it determines that the bus is in a de-voltage state. On the one hand, when there is a bus in the distribution network that is in a de-voltage state, but the criterion for the automatic detection equipment to obtain the status of each bus in the distribution network fails, the subsequent process can be started by triggering the self-healing simulation mode of the de-voltage bus. On the other hand, the de-voltage state of the bus can be simulated to know when the bus can be transferred, which can be used for decision-making or training.

[0065] Optionally, based on the above embodiment, step S210 includes: obtaining the line voltage of each bus in the distribution network; when it is detected that the line voltage of a bus in the distribution network is lower than a first set voltage value and the bus is in a non-maintenance state, it is determined that the bus is in a voltage-loss state.

[0066] It is understandable that the first set voltage value can be freely set by the user according to actual conditions.

[0067] Optionally, based on the above embodiment, continue to refer to Figure 2 , step S220 includes:

[0068] S221. When it is detected that a bus in the distribution network is in a voltage loss state, the status of a program for obtaining a bus voltage loss event list.

[0069] S222. When the program of the bus undervoltage event list is in an open state, the bus undervoltage event list is controlled to refresh the bus undervoltage event information; wherein the bus undervoltage event information includes the bus undervoltage time, the bus undervoltage event description, the bus undervoltage event type and the bus undervoltage execution status.

[0070] S223. When it is detected that the busbar undervoltage event information is in a processed state, the busbar undervoltage event list is controlled to refresh the busbar undervoltage execution status, the busbar undervoltage processing node and the busbar undervoltage processing person; wherein, the busbar undervoltage event list also includes the busbar undervoltage processing node and the busbar undervoltage processing person.

[0071] Optionally, based on the above embodiment, continue to refer to Figure 2 , after step S223, further comprising:

[0072] S224. Synchronously prohibit other nodes or other processors from processing the busbar pressure loss event information.

[0073] Optionally, based on the above embodiment, step S230 includes: shielding the scheme with abnormal operating data according to the busbar undervoltage event list, the real-time operation status of the distribution network, and the user information of the power supply object of the busbar in the distribution network that is in the undervoltage state, and listing the power transfer schemes of all buses in the distribution network that are in the undervoltage state on the busbar undervoltage self-healing interface in a preset priority order.

[0074] Among them, the preset priority order may include: first, the scheme in which the connecting switch is a three-remote switch is given priority. Secondly, the scheme in which the opposite power supply and the local power supply come from different plants and stations is given priority (the opposite plant and station is determined by the opposite load). Thirdly, the scheme that can normally calculate the load rate after transfer is given priority. Thirdly, the scheme with a lower load on the opposite line is given priority (the load is determined by the outlet current of the opposite line). Finally, the scheme in which the opposite line power supply object includes multiple power users (that is, the opposite line load attribute has "multiple power sources").

[0075] The embodiment of the present invention can list the transfer plans of the automated coverage lines and the non-automated coverage lines at the same time. The distribution network dispatcher can adjust the transfer plan of each automated coverage line according to actual needs, and can refer to the transfer plan of the non-automated coverage line to command the on-site emergency repair work.

[0076] Optionally, based on the above embodiment, continue to refer to Figure 2 , S240 includes:

[0077] S241. Verify the current sampling conditions of each bus in the distribution network, the operating status of the equipment in the distribution network, and the power supply capacity of each bus in the distribution network.

[0078] It should be noted that as long as the verification logic is not met, the verification will be prompted to fail. The distribution network dispatcher can force the verification after confirming that there is no impact. The solution for forcing the verification still retains the reason for the verification failure. The current sampling conditions of each bus in the distribution network include: if the line and main transformer current at this end and the other end are not set for sampling or have infinite values, the verification will fail. The operating status of the equipment in the distribution network includes: if the quality code of the interconnecting switch is abnormal and the interconnecting switch is not three-remote, the verification will fail. If it is forced to pass, the interconnecting switch will not perform remote control. If the switch is disconnected or the protection action occurs on the lines at both ends within 30s before and after the busbar pressure loss event, the verification will fail. The power supply capacity verification of each bus in the distribution network can include: if after the transfer, if the opposite end line or main transformer is heavily overloaded, the verification will fail.

[0079] S242. When the verification is passed, the ticket is automatically generated and sent to the dispatching operation management system.

[0080] It can be understood that when the verification is passed, the ticket is automatically sent to the dispatching operation management system, and related operations can be performed subsequently through programmed operations.

[0081] S243. Implement one-key remote control operation according to the selected busbar pressure loss self-healing solution to restore power to the busbar.

[0082] It can be understood that the embodiments of the present invention can directly implement one-key remote control operation according to the transfer plan, realize parallel execution and sequential execution, real-time display of execution steps, direct skipping of non-remote control steps, pause and terminate the plan execution, and historical traceability of execution results.

[0083] The embodiments of the present invention can realize the automatic perception of large-scale power outage faults, the rapid restoration of power to the automated coverage lines, and the auxiliary decision-making of the non-automated coverage lines, which greatly improves the emergency handling efficiency of the distribution network dispatching and shortens the fault power outage time. The research results can be used in various power supply bureaus of the Guangdong Power Grid and have great application prospects. By formulating rigorous busbar undervoltage criterion, the sensitivity of busbar undervoltage monitoring is guaranteed and the risk of misjudgment and misoperation of functions is reduced. It is possible to realize the differentiated execution of the transfer schemes of the automated coverage lines and the non-automated coverage lines, the automated coverage lines are automatically executed, and the non-automated coverage lines provide reference schemes, which effectively improves the work efficiency of the distribution network dispatching emergency handling. And by fully considering the operating conditions and load capacity of the opposite end line or main transformer, the risk of secondary events after the transfer can be reduced.
