Description

Technical Field

[0001] The present invention relates to the technical field of power outage management, and in particular to a power outage management analysis method and system based on power conservation of a power generation vehicle. Background Art

[0002] With the development of science and technology and the progress of society, people's requirements for power and power quality are also increasing day by day. Once an accident occurs in the power grid and causes a large-scale power outage, it will not only cause inconvenience to people's daily lives, but also affect social stability and economic development. In order to maintain the normal operation of the distribution network, each distribution network management department regularly inspects the distribution network according to the pre-established power outage plan to ensure the normal operation of the distribution network.

[0003] During the process of power outage for maintenance of the distribution network, users often call the power management department to obtain specific information about power restoration and power outage due to sudden power outage and without receiving power outage information. In this regard, the existing technology generates a power outage analysis report to reply to users by manually querying the corresponding power outage plan, but due to the limited efficiency of manual query, it is impossible to conduct power outage analysis in a timely manner.

[0004] At the same time, the technology for generating power outage information based on power outage plans does not take into account power supply protection. For example, in order to reduce the social impact of power outages, some areas will use power supply protection equipment such as power generators to replace power supply equipment under maintenance. As a result, only a short power outage will occur in these areas, resulting in the actual power outage situation of users not matching the power outage situation in the power outage information, which in turn causes the power outage information received by users to be inaccurate. Summary of the invention

[0005] In order to solve the above technical problems, the present invention discloses a power outage management and analysis method and system based on power supply protection of power generation vehicles, which are used to improve the efficiency and accuracy of power outage management and analysis.

[0006] In order to achieve the above object, the present invention discloses a power outage management and analysis method based on power supply protection of a power generation vehicle, comprising: Based on the request time of the power outage event, multiple planned power outage work orders and multiple power supply work orders for generator vehicles are obtained; Obtain the power outage line of the distribution network of the planned power outage work order and the distribution network access node of the generator vehicle in the power supply protection work order of the generator vehicle, so as to establish a mapping relationship between the planned power outage work order and the power supply protection work order of the generator vehicle; Obtaining the power grid topology route where the power outage event is located, and selecting a target planned power outage work order from a plurality of planned power outage work orders according to the power grid topology route and the power outage line of the distribution network; Determine the target power supply work order for the power generation vehicle corresponding to the target planned power outage work order based on the mapping relationship, and obtain the power outage information corresponding to the target planned power outage work order and the power supply information in the power supply work order for the power generation vehicle; A power outage analysis report corresponding to the power outage event is generated based on the power outage information and the power conservation information.

[0007] The present invention discloses a power outage management and analysis method based on power supply protection of a power generation vehicle, which obtains work orders based on the request time of the power outage event to reduce the processing volume of the work orders, thereby improving the efficiency of the analysis. Among them, the planned power outage work order and the power supply protection work order of the power generation vehicle are obtained at the same time, so as to improve the accuracy of the power outage analysis by combining the planned power outage and power supply protection. Secondly, in the process of power outage analysis, the planned power outage work order is matched with the power supply protection work order of the power generation vehicle by using the power outage line of the distribution network of the planned power outage work order and the distribution network access node of the power generation vehicle, so as to obtain the corresponding power outage information and power supply protection information according to the corresponding relationship, thereby reducing the processing volume of the power supply protection work order and improving the efficiency of the power outage analysis. Then, the power grid topology route where the power outage event is located is matched with the power outage line of the distribution network to accurately obtain the target planned power outage work order corresponding to the power outage event, so as to accurately obtain the power outage information corresponding to the power outage event from the target planned power outage work order, and then obtain the power supply protection information corresponding to the power outage information, so as to improve the accuracy of the power outage analysis. Finally, a power outage analysis report corresponding to the power outage event is generated based on the acquired power outage information and the power protection information, thereby improving the efficiency and accuracy of power outage management analysis.

[0008] As a preferred example, the obtaining of multiple planned power outage work orders and multiple power supply work orders for power generation vehicles based on the request time of the power outage event includes: For any planned power outage work order and any power supply work order for the generator; Extract the planned power outage time in the planned power outage work order and the planned power supply time in the power supply work order of the generator vehicle; Obtaining a power outage difference between the requested time and the planned power outage time and a power conservation difference between the requested time and the planned power conservation time; When the power outage difference is less than or equal to a preset duration threshold, the planned power outage work order is used as the planned power outage work order corresponding to the power outage event; When the power protection difference is less than or equal to the duration threshold, the power protection work order for the generating vehicle is used as the power protection work order for the generating vehicle corresponding to the power outage event.

[0009] In the above scheme, in order to reduce the processing volume of work orders, the target work orders are obtained from a small range of work orders to improve the efficiency of power outage analysis. The planned power outage time and planned power supply time in each work order are used to filter out the work orders within a certain range of the current request time, which not only ensures the accuracy of work order acquisition, but also reduces the number of work orders, thereby improving the efficiency and accuracy of power outage analysis.

[0010] As a preferred example, the obtaining of multiple planned power outage work orders and multiple power supply work orders for power generation vehicles based on the request time of the power outage event also includes: Obtain multiple initial planned power outage work orders and multiple initial power supply car protection work orders from a database storing work orders; Obtaining the power outage approval status of the initial planned power outage work order and the power supply approval status of the initial power supply work order for the generator vehicle; For any initial planned power outage work order and any initial generator car power protection work order; When the power outage approval status of the initial planned power outage work order is passed, the initial planned power outage work order is used as the planned power outage work order; When the power supply approval status of the initial power supply work order for the power generation vehicle is passed, the initial power supply work order for the power generation vehicle is used as the power supply work order for the power generation vehicle.

[0011] In the above scheme, based on the cancellation, modification and unreasonableness that may occur during the work order formulation process, multiple corresponding work orders may appear for the same planned power outage event. At this time, in order to avoid the acquisition of useless work orders, the approval status of each work order can be used to verify the eligibility of the work order, and then only the work orders with the approval status of passed can be obtained to obtain subsequent power outage information and power supply protection information, thereby improving the efficiency of power outage analysis.

[0012] As a preferred example, the obtaining of the power outage line of the distribution network of the planned power outage work order and the distribution network access node of the generator vehicle in the power supply protection work order of the generator vehicle to establish a mapping relationship between the planned power outage work order and the power supply protection work order of the generator vehicle includes: Extracting the planned power outage line in the planned power outage work order and the power generation position corresponding to the generator car in the generator car power protection work order; According to the planned outage line and the power generation location, the distribution network outage line corresponding to the planned outage line and the distribution network access node corresponding to the power generation location are obtained from the distribution network GIS system; The distribution network access node and the distribution network power outage line are matched to obtain a mapping relationship between the planned power outage work order and the power supply work order of the power generation vehicle.

[0013] In the above scheme, when the power supply is planned to be maintained by the generator truck, the equipment powered by the generator truck must be in a power outage state, that is, the planned power outage work order and the power supply work order of the generator truck are in a corresponding relationship. At this time, in order to improve the efficiency of the power outage analysis, the matching degree of the planned power outage line and the distribution network access node is used to obtain the correspondence between the planned power outage work order and the power supply work order of the generator truck, so that the number of power supply work orders processed by the generator truck is reduced according to the corresponding relationship, thereby improving the efficiency of the power outage analysis.

[0014] As a preferred example, the matching of the distribution network access node and the distribution network power outage line to obtain the mapping relationship between the planned power outage work order and the power supply work order of the power generation vehicle includes: For any of the planned outage work orders; Traverse the power outage lines of the distribution network corresponding to the planned power outage work order, and obtain the switch access node corresponding to each standby switch position; For any of the above mentioned power generation vehicle power maintenance work orders; When the distribution network access node of the power supply protection work order of the generator vehicle is consistent with the switch access node, a mapping relationship between the power supply protection work order of the generator vehicle and the planned power outage work order is established.

[0015] In the above scheme, the power generation vehicle is often connected to the node where the standby switch is located in the line to supply power. Therefore, when matching the planned power outage work order with the power supply work order of the generator vehicle, the node corresponding to the standby switch position in the power outage line of the distribution network is used for matching, which can improve the matching efficiency and the matching accuracy, thereby ensuring the accuracy of power supply information acquisition.

[0016] As a preferred example, the obtaining of the grid topology route where the power outage event is located, and selecting a target planned power outage work order from a plurality of planned power outage work orders according to the grid topology route and the distribution network power outage line, includes: Acquire the request address of the power outage event, so as to obtain the power grid topology route where the power outage event is located from the distribution network GIS system according to the request address; Searching each topological branch of the power outage line of the distribution network to obtain multiple power outage topological routes corresponding to the power outage line of the distribution network; The route overlap between the power grid topology route and the power outage topology route is obtained, so as to select a target planned power outage work order from the plurality of planned power outage work orders according to the route overlap.

[0017] In the above scheme, each topological branch of the distribution network power outage line is searched to determine the power outage scope caused by the distribution network power outage line, and the searched power outage topological route is used to improve the efficiency of power outage scope retrieval, and then based on the power grid topological route where the power outage event is located and the power outage topological route, the accuracy of target planned power outage work order screening is ensured, thereby improving the accuracy of power outage analysis.

[0018] As a preferred example, the step of obtaining the request address of the power outage event, so as to obtain the power grid topology route where the power outage event is located from the distribution network GIS system according to the request address, includes: Parsing the power outage event to obtain a user input address; Extracting keywords from the address input by the user, and matching the keywords with standard keywords preset in a standard address library to obtain a standard address corresponding to the address input by the user; Obtaining the substation number associated with the standard address, and calling the GIS service of the distribution network to obtain the local power grid topology network where the substation number is located; The correspondence between substations, lines, power equipment, and substation area numbers in the local power grid topology network is obtained to obtain the power grid topology route where the power outage event occurs based on the correspondence.

[0019] In the above scheme, during the positioning process, the user's area number is first determined based on the address entered by the user to reduce the time of event positioning, thereby improving the efficiency of power outage analysis. When acquiring the power grid topology route, the GIS service of the distribution network and the correspondence between the substation, line, power equipment, and area number in the local power grid topology network are used to ensure the efficiency and accuracy of the power grid topology route acquisition.

[0020] As a preferred example, searching each topological branch of the power outage line of the distribution network to obtain multiple power outage topological routes corresponding to the power outage line of the distribution network includes: Taking the power outage line of the distribution network as a starting point, searching for each topological branch connected to the power outage line of the distribution network; For any of the topological branches; When the device searched is a bus, determine whether the voltage level of the bus is the same as the voltage level of the power station to which the bus belongs. If they are not the same, stop searching the topology branch and use the previous device of the bus as the power source. If they are the same, continue searching. When the searched device is a distribution transformer, the search for the corresponding topology branch is stopped; If the searched device is a normally open contact switch, determine whether the normally open contact switch is in the closed switch list, if so, continue searching, if not, stop searching the corresponding topology branch; If the device found is a power device other than a busbar, transformer or normally open contact switch, continue searching; After multiple transformers corresponding to the power outage line of the distribution network are obtained based on the search, a grid connectivity analysis is performed on each of the transformers according to the power outage line of the distribution network to obtain multiple power outage topology lines corresponding to the power outage line of the distribution network.

[0021] In the above scheme, when searching for multiple topological branches connected to the power outage line of the distribution network to determine the power outage range, the search efficiency can be improved by setting the type of the search device and then determining the search progress of each topological branch, thereby improving the efficiency of the search and thus improving the efficiency of the power outage analysis. After the multiple transformers corresponding to the power outage line of the distribution network are known based on the search, a power grid connectivity analysis is performed on each of the transformers according to the power outage line of the distribution network to determine the multiple power outage topological routes corresponding to the power outage line of the distribution network, so as to improve the accuracy of the power outage topological route search and thus improve the accuracy of the power outage analysis.

[0022] As a preferred example, determining the target power generation vehicle power supply work order corresponding to the target planned power outage work order based on the mapping relationship, and obtaining the power outage information corresponding to the target planned power outage work order and the power supply information in the target power generation vehicle power supply work order, includes: Respectively perform data conversion and typos correction on the target planned power outage work order and the target power supply work order for the power generation vehicle to obtain a revised planned power outage work order and a revised power supply work order for the power generation vehicle; Inputting the revised planned power outage work order and the revised power generation vehicle power protection work order into a pre-built deep learning model respectively to locate the power outage text position of the revised planned power outage work order and the power protection text position of the revised power generation vehicle power protection work order; Extracting the power outage information of the revised planned power outage work order based on the power outage text position; The power supply information of the revised power supply work order for the power generation vehicle is extracted based on the power supply text position.

[0023] In the above scheme, data conversion and typo correction are performed on the acquired planned power outage work order and the power supply protection work order of the generator vehicle respectively to remove the erroneous information in the work order and improve the accuracy of information extraction. Then, the starting position used to describe the power outage information and the power supply protection information in the work order is located through the trained deep learning model, and then the corresponding power outage information and power supply protection information are extracted from the planned power outage work order and the power supply protection work order of the generator vehicle according to the starting position to improve the accuracy and efficiency of information acquisition, thereby improving the efficiency and accuracy of power outage analysis.

[0024] As a preferred example, generating a power outage analysis report corresponding to the power outage event based on the power outage information and the power protection information includes: Determining a power outage type according to the power outage information to match a report template corresponding to the power outage type; The configuration information of the report template is obtained, so as to add the power outage information and the power protection information to the report template according to the configuration information to form a power outage analysis report.

[0025] In the above scheme, the report template corresponding to the power outage information is matched, so as to use the report template to generate a power outage analysis report containing complete information of the power outage information and the power protection information, thereby ensuring that the user obtains an accurate power outage analysis report.

[0026] On the other hand, the present invention discloses a power outage management and analysis system based on power generation vehicle power protection, including a work order extraction module, a relationship mapping module, a work order screening module, an information extraction module and a power outage analysis module; The work order extraction module is used to obtain multiple planned power outage work orders and multiple power supply work orders for power generation vehicles based on the request time of the power outage event; The relationship mapping module is used to obtain the power distribution network outage line of the planned power outage work order and the distribution network access node of the generator vehicle in the power supply protection work order of the generator vehicle, so as to establish a mapping relationship between the planned power outage work order and the power supply protection work order of the generator vehicle; The work order screening module is used to obtain the power grid topology route where the power outage event is located, and select a target planned power outage work order from a plurality of planned power outage work orders according to the power grid topology route and the power distribution network power outage line; The information extraction module is used to determine the target power generation vehicle power protection work order corresponding to the target planned power outage work order based on the mapping relationship, and obtain the power outage information corresponding to the target planned power outage work order and the power protection information in the target power generation vehicle power protection work order; The power outage analysis module is used to generate a power outage analysis report corresponding to the power outage event based on the power outage information and the power protection information.

[0027] The present invention discloses a power outage management and analysis system based on power supply protection of power generation vehicles, which obtains work orders based on the request time of power outage events to reduce the processing volume of work orders and thus improve the efficiency of analysis. Among them, the planned power outage work order and the power supply protection work order of the power generation vehicle are obtained at the same time, so as to improve the accuracy of power outage analysis by combining the planned power outage and power supply protection.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0030] Embodiment 1 This embodiment discloses a power outage management and analysis method based on power generation vehicle power protection, which is used to improve the efficiency and accuracy of power outage management and analysis. Figure 1 , mainly including steps 101 to 105, wherein the steps are mainly: Step 101: Based on the request time of the power outage event, a plurality of planned power outage work orders and a plurality of power supply work orders for power generation vehicles are obtained.

[0031] Step 102: Obtain the power outage line of the distribution network of the planned power outage work order and the distribution network access node of the generator vehicle in the generator vehicle power protection work order to establish a mapping relationship between the planned power outage work order and the generator vehicle power protection work order.

[0032] Step 103: Obtain the grid topology route where the power outage event is located, and select a target planned power outage work order from the multiple planned power outage work orders according to the grid topology route and the distribution network power outage line.

[0033] Step 104: Determine the target power supply work order for the power generation vehicle corresponding to the target planned power outage work order based on the mapping relationship, and obtain the power outage information corresponding to the target planned power outage work order and the power supply information in the power supply work order for the power generation vehicle.

[0034] Step 105: Generate a power outage analysis report corresponding to the power outage event based on the power outage information and the power protection information.

[0035] In some implementations of this embodiment, when extracting the work order in step 101, the following steps are preferably performed to improve the efficiency and accuracy of work order extraction. Specifically, the steps are: Step 1011: for any planned power outage work order and any power supply work order for a power generator; extract the planned power outage time in the planned power outage work order and the planned power supply time in the power supply work order for the power generator; Step 1012: obtaining a power outage difference between the requested time and the planned power outage time and a power conservation difference between the requested time and the planned power conservation time; Step 1013: When the power outage difference is less than or equal to a preset duration threshold, the planned power outage work order is used as the planned power outage work order corresponding to the power outage event; Step 1014: When the power protection difference is less than or equal to the duration threshold, the power protection work order for the generating vehicle is used as the power protection work order for the generating vehicle corresponding to the power outage event.

[0036] In this embodiment, the above steps are to reduce the processing volume of work orders, so as to obtain the target work order from a small range of work orders and thus improve the efficiency of power outage analysis. The planned power outage time and planned power supply time in each work order are used to filter out the work orders within a certain range of the current request time, which not only ensures the accuracy of work order acquisition, but also reduces the number of work orders, thereby improving the efficiency and accuracy of power outage analysis.

[0037] In some implementations of this embodiment, when the work order is obtained in steps 1011 to 1014, a standard for obtaining the work order can be formulated based on the following steps to further reduce the processing volume of the work order according to the standard, so as to improve the efficiency of obtaining the work order. Specifically, the steps are: Step 1015: Acquire multiple initial planned power outage work orders and multiple initial generator vehicle power protection work orders from a database storing work orders; Step 1016: obtaining the power outage approval status of the initial planned power outage work order and the power supply approval status of the initial power supply work order for the generator vehicle; Step 1017: for any initial planned power outage work order and any initial power generation vehicle power protection work order; when the power outage approval status of the initial planned power outage work order is passed, the initial planned power outage work order is used as the planned power outage work order; Step 1018: When the power supply approval status of the initial power supply work order for the power generation vehicle is passed, the initial power supply work order for the power generation vehicle is used as the power supply work order for the power generation vehicle.

[0038] In this embodiment, the above steps are based on the fact that cancellation, modification and unreasonableness may occur during the work order formulation process, resulting in multiple corresponding work orders for the same planned power outage event. At this time, in order to avoid the acquisition of useless work orders, the approval status of each work order can be used to verify the eligibility of the work order, and then only the work orders with an approval status of passed are obtained to obtain subsequent power outage information and power supply protection information, thereby improving the efficiency of power outage analysis.

[0039] In some implementations of this embodiment, when establishing the mapping relationship between the planned power outage work order and the power supply work order of the generator vehicle, the following steps are preferably performed to improve the efficiency and accuracy of work order matching, thereby improving the efficiency and accuracy of power outage analysis. Specifically, the steps include: Step 1021: extracting the planned power outage line in the planned power outage work order and the power generation position corresponding to the generator car in the generator car power protection work order; Step 1022: acquiring, from the distribution network GIS system, a distribution network outage line corresponding to the planned outage line and a distribution network access node corresponding to the power generation location according to the planned outage line and the power generation location; Step 1023: Match the distribution network access node and the distribution network power outage line to obtain a mapping relationship between the planned power outage work order and the power supply work order for the generator vehicle.

[0040] In this embodiment, when the power supply is planned to be maintained by the generator truck in the above steps, the equipment powered by the generator truck must be in a power outage state, that is, the planned power outage work order and the power supply work order of the generator truck are in a corresponding relationship. At this time, in order to improve the efficiency of the power outage analysis, the matching degree of the planned power outage line and the distribution network access node is used to obtain the correspondence between the planned power outage work order and the power supply work order of the generator truck, so that the number of power supply work orders processed by the generator truck is reduced according to the corresponding relationship, thereby improving the efficiency of the power outage analysis.

[0041] In some implementations of this embodiment, in step 1023, when matching the distribution network access node and the distribution network power outage line, the following steps are preferably performed to match the line and the node, thereby improving the accuracy of the matching to ensure the accuracy of the power outage analysis. Specifically, the steps include: Step 10231: for any of the planned power outage work orders; traverse the power outage lines of the distribution network corresponding to the planned power outage work order, and obtain the switch access node corresponding to each standby switch position; Step 10232: For any of the power supply work orders for the power generation vehicle; when the distribution network access node of the power supply work order for the power generation vehicle is consistent with the switch access node, a mapping relationship between the power supply work order for the power generation vehicle and the planned power outage work order is established.

[0042] In this embodiment, the above steps are based on the node where the standby switch position is located in the power supply line where the power generation vehicle is often connected. Therefore, when matching the planned power outage work order with the power protection work order of the power generation vehicle, the node corresponding to the standby switch position in the power outage line of the distribution network is used for matching, which can improve the matching efficiency and the matching accuracy, thereby ensuring the accuracy of power protection information acquisition.

[0043] In some implementations of this embodiment, step 103 determines the target planned power outage work order and the target power supply work order for the power generation vehicle corresponding to the power outage event based on the following steps to improve the efficiency and accuracy of the power outage analysis. Specifically, the steps include: Step 1031: Acquire the request address of the power outage event, so as to obtain the power grid topology route where the power outage event is located from the distribution network GIS system according to the request address; Step 1032: Search each topological branch of the power outage line of the distribution network to obtain multiple power outage topological routes corresponding to the power outage line of the distribution network; Step 1033: Obtain the route overlap between the power grid topology route and the power outage topology route, so as to select a target planned power outage work order from the plurality of planned power outage work orders according to the route overlap.

[0044] In this embodiment, the above steps search each topological branch of the distribution network outage line to determine the power outage range caused by the distribution network outage line, and use the searched power outage topology route to improve the efficiency of power outage range retrieval, and then based on the power grid topology route where the power outage event is located and the power outage topology route, ensure the accuracy of target planned power outage work order screening, thereby improving the accuracy of power outage analysis.

[0045] In some implementations of this embodiment, the step 1031 preferably performs the following steps to obtain the grid topology route to improve the efficiency and accuracy of the power outage analysis. Specifically, the steps include: Step 10311: parse the power outage event to obtain the user input address; Step 10312: extract keywords from the address input by the user, and match the keywords with standard keywords preset in the standard address library to obtain a standard address corresponding to the address input by the user; Step 10313: Obtain the substation number associated with the standard address, and call the GIS service of the distribution network to obtain the local power grid topology network where the substation number is located; Step 10314: Obtain the correspondence between substations, lines, power equipment, and substation area numbers in the local power grid topology network, so as to obtain the power grid topology route where the power outage event occurs based on the correspondence.

[0046] In this embodiment, during the positioning process, the above steps first determine the substation number where the user is located based on the address input by the user to reduce the time of event positioning, thereby improving the efficiency of power outage analysis. When acquiring the power grid topology route, the GIS service of the distribution network and the correspondence between the substation, line, power equipment, and substation number in the local power grid topology network are used to ensure the efficiency and accuracy of the acquisition of the power grid topology route.

[0047] In some implementations of this embodiment, the step 1032 preferably performs the following steps to search for topological lines, so as to improve the efficiency and accuracy of the search, thereby improving the efficiency and accuracy of the power outage analysis. Specifically, the steps include: Step 10321: starting from the power outage line of the distribution network, searching for each topological branch connected to the power outage line of the distribution network; Step 10322: for any of the topological branches; when the searched device is a bus, determine whether the voltage level of the bus is the same as the voltage level of the power station to which the bus belongs. If they are not the same, stop searching the topological branch and use the previous device of the bus as the power source. If they are the same, continue searching. When the searched device is a distribution transformer, stop searching the corresponding topological branch. If the searched device is a normally open contact switch, determine whether the normally open contact switch is in the closed switch list. If so, continue searching. If not, stop searching the corresponding topological branch. If the searched device is a power device other than a bus, a transformer or a normally open contact switch, continue searching. Step 10323: After multiple transformers corresponding to the power outage line of the distribution network are obtained based on the search, a grid connectivity analysis is performed on each of the transformers according to the power outage line of the distribution network to obtain multiple power outage topology lines corresponding to the power outage line of the distribution network.

[0048] In this embodiment, when searching for multiple topological branches connected to the power outage line of the distribution network to determine the power outage range, the above steps can improve the efficiency of the search by setting the type of the search device and then determining the search progress of each topological branch, thereby improving the efficiency of the power outage analysis. After the multiple transformers corresponding to the power outage line of the distribution network are known based on the search, a power grid connectivity analysis is performed on each of the transformers according to the power outage line of the distribution network to determine multiple power outage topological routes corresponding to the power outage line of the distribution network, so as to improve the accuracy of the power outage topological route search, thereby improving the accuracy of the power outage analysis.

[0049] In some implementations of this embodiment, step 104 extracts power outage information and power protection information based on the following steps to improve the efficiency and accuracy of extraction, thereby improving the efficiency and accuracy of power outage analysis. Specifically, the steps include: Step 1041: performing data conversion and typos correction on the target planned power outage work order and the target power supply work order for the power generation vehicle, respectively, to obtain a revised planned power outage work order and a revised power supply work order for the power generation vehicle; Step 1042: inputting the revised planned power outage work order and the revised power generation vehicle power protection work order into a pre-built deep learning model to locate the power outage text position of the revised planned power outage work order and the power protection text position of the revised power generation vehicle power protection work order; Step 1043: extracting the power outage information of the revised planned power outage work order based on the power outage text position; Step 1044: extracting the power supply information of the revised power supply work order for the power generation vehicle based on the power supply text position.

[0050] In this embodiment, the above steps perform data conversion and typo correction on the acquired planned power outage work order and the power supply protection work order of the generator vehicle, respectively, so as to remove the erroneous information in the work order and improve the accuracy of information extraction. Then, the trained deep learning model is used to locate the starting position for describing the power outage information and the power supply protection information in the work order, and then the corresponding power outage information and power supply protection information are extracted from the planned power outage work order and the power supply protection work order of the generator vehicle according to the starting position, so as to improve the accuracy and efficiency of information acquisition, thereby improving the efficiency and accuracy of power outage analysis.

[0051] In some implementations of this embodiment, step 105 generates an analysis report based on the following steps to completely generate a power outage analysis result. Specifically, the steps include: Step 1051: Determine a power outage type according to the power outage information to match a report template corresponding to the power outage type; Step 1052: Acquire the configuration information of the report template, and add the power outage information and the power protection information to the report template according to the configuration information to form a power outage analysis report.

[0052] In this embodiment, the above steps match the report template corresponding to the power outage information, so as to use the report template to generate a power outage analysis report containing complete information of the power outage information and the power protection information, thereby ensuring that the user obtains an accurate power outage analysis report.

[0053] On the other hand, the present invention also discloses a power outage management and analysis system based on power generation vehicle power protection. The specific structure of the power outage management and analysis system can be found in Figure 2 , including a work order extraction module 201, a relationship mapping module 202, a work order screening module 203, an information extraction module 204 and a power outage analysis module 205.

[0054] The work order extraction module 201 is used to obtain multiple planned power outage work orders and multiple power supply work orders for power generation vehicles based on the request time of the power outage event.

[0055] The relationship mapping module 202 is used to obtain the power distribution network outage line of the planned power outage work order and the distribution network access node of the generator vehicle in the generator vehicle power protection work order to establish a mapping relationship between the planned power outage work order and the generator vehicle power protection work order.

[0056] The work order screening module 203 is used to obtain the power grid topology route where the power outage event is located, and select a target planned power outage work order from a plurality of planned power outage work orders according to the power grid topology route and the distribution network power outage line.

[0057] The information extraction module 204 is used to determine the target power generation vehicle power supply work order corresponding to the target planned power outage work order based on the mapping relationship, and obtain the power outage information corresponding to the target planned power outage work order and the power supply information in the target power generation vehicle power supply work order.

[0058] The power outage analysis module 205 is used to generate a power outage analysis report corresponding to the power outage event based on the power outage information and the power protection information.

[0059] The power outage management and analysis method based on power supply protection of power generation vehicles provided in this embodiment obtains work orders based on the request time of the power outage event to reduce the processing volume of work orders, thereby improving the efficiency of analysis. Among them, the planned power outage work order and the power supply protection work order of the power generation vehicle are obtained at the same time, so as to improve the accuracy of power outage analysis by combining the planned power outage and power supply protection. Secondly, in the process of power outage analysis, the planned power outage work order is matched with the power supply protection work order of the power generation vehicle one by one by using the power outage line of the distribution network of the planned power outage work order and the distribution network access node of the power generation vehicle, so as to obtain the corresponding power outage information and power supply protection information according to the corresponding relationship, thereby reducing the processing volume of the power supply protection work order and improving the efficiency of power outage analysis. Then, the power grid topology route where the power outage event is located is matched with the power outage line of the distribution network to accurately obtain the target planned power outage work order corresponding to the power outage event, so as to accurately obtain the power outage information corresponding to the power outage event from the target planned power outage work order, and then obtain the power supply protection information corresponding to the power outage information, so as to improve the accuracy of power outage analysis. Finally, a power outage analysis report corresponding to the power outage event is generated based on the acquired power outage information and the power protection information, thereby improving the efficiency and accuracy of power outage management analysis.

[0060] Embodiment 2 In the prior art, when the power distribution network is overhauled and the power is restored by the generator truck, users often consult the power company according to their own needs to obtain specific power restoration information, power outage duration, etc. due to the sudden power outage and without receiving the power outage information. In the prior art, in order to appease the emotions of users, the power company often arranges a large number of manual customer service to respond to user inquiries, but the method of manually responding to the current consulting users about the power outage not only requires a huge amount of manpower costs, but also because the amount of information to be processed is relatively large, it is impossible for the manual to locate the user in a short time to obtain his specific power outage and power restoration information, resulting in a poor user consultation experience and an increased risk of customer complaints.

[0061] In order to solve the above technical problems, this embodiment provides a power outage management and analysis method based on power generation vehicle power protection, which is used to improve the efficiency and accuracy of power outage analysis, thereby meeting the consultation needs of users. Specifically, the specific implementation process of the power outage management and analysis method can be referred to Figure 3 , mainly including steps 301 to 306, the steps are mainly: Step 301: Obtain the request time of the reported user power outage event to obtain a plurality of first planned power outage work orders and a plurality of first power generation vehicle power protection work orders associated with the request time.

[0062] In this embodiment, the steps are mainly as follows: obtaining the request time of the user's power outage event, and obtaining the approval status of each work order from the database storing the work orders; obtaining multiple original planned power outage work orders and multiple original power supply work orders of the power generation vehicle with the approval status of approved from the database; inputting the original planned power outage work order and the original power supply work order of the power generation vehicle into the preset text recognition model respectively, so as to extract the planned power outage start time and the planned power outage end time in the original planned power outage work order, and the planned power supply start time and the planned power supply end time in the original power supply work order of the power generation vehicle. According to the preset time window, the request time and the planned power outage start time, the planned power outage end time, the planned power supply start time and the planned power supply end time, the multiple first planned power outage work orders and multiple first power supply work orders of the power generation vehicle are selected from the multiple original planned power outage work orders and the multiple original power supply work orders of the power generation vehicle.

[0063] Specifically, when a power outage occurs in a certain area, the user can report the power outage event by logging on to the website or making a phone call. After receiving the power outage event input by the user or staff, the power supply system first obtains the input time of the power outage event as the request time. Secondly, when the distribution network is planned to be out of service and the power generation vehicle is used to protect the power during the planned power outage, it is necessary to declare the planned power outage work order and the power generation vehicle power protection work order in advance in the power supply system to perform subsequent power outage operations and power protection operations. In this regard, the power outage information and power protection information corresponding to the power outage event can be obtained by querying the work order. Furthermore, since a large number of work orders are stored in the database, and these work orders include approved pending work orders and scrapped work orders that have not been approved. If a power outage event occurs, it means that the planned power outage work order corresponding to the area where the power outage event occurs has been approved and is being executed. In this regard, in order to reduce the amount of data queried for the work order and the accuracy of the subsequent corresponding data acquisition, multiple original planned power outage work orders and multiple original power generation vehicle power protection work orders can be first screened out according to the approval status of each work order.

[0064] Furthermore, after screening based on the approval status, the search scope can be further narrowed and the search progress can be improved according to the pre-execution time recorded in each work order. For example, when the request time is 13:56 on January 2, 2025, the planned power outage work order and the power supply work order for the power generation vehicle close to the request time can be found according to the dynamically set time window. Specifically, a text data model that can perform text content recognition on the work order to extract the text data representing the time in the work order can be pre-trained to extract the corresponding time from the work order according to the text data model, such as the planned start power outage time and the planned end power outage time in the planned power outage work order, and the planned start power supply time and the planned end power supply time in the original power supply work order for the power generation vehicle. Then, the time difference between the planned end power supply time and the request time is obtained by calculating the planned start power outage time, the planned end power outage time, and the planned start power supply time. Then, multiple first planned power outage work orders and multiple first power supply work orders for the power generation vehicle are screened out.

[0065] Step 302: Obtain the distribution network outage line corresponding to the first planned power outage work order and the distribution network access node of the generator vehicle in the first generator vehicle power protection work order, and establish an association relationship between the first generator vehicle power protection work order and the first planned power outage work order based on the distribution network outage line and the distribution network access node.

[0066] In this embodiment, the step mainly includes: inputting the first generator vehicle power supply protection work order and the first planned power outage work order into the pre-built text recognition model to obtain the planned power outage line in the first planned power outage work order and the power generation position of the generator vehicle in the first generator vehicle power supply protection work order; obtaining the distribution network power outage line corresponding to the planned power outage line from the distribution network GIS system according to the planned power outage line and the power generation position; matching the distribution network access node and the distribution network power outage line to obtain the association relationship between the first generator vehicle power supply protection work order and the first planned power outage work order.

[0067] Specifically, the first power supply work order for the generator vehicle and the first planned power outage work order are input into a pre-built text recognition model for identifying the power outage area and the power generation position of the generator vehicle, so as to output the specific power generation position of the generator vehicle in each power supply work order for the generator vehicle and the power outage area of ​​the planned power outage in each planned power outage work order; then the GIS service of the distribution network is called, and the longitude and latitude information of the power outage area and the distribution network access node are input to obtain the local power grid topology network where the longitude and latitude information is located, and the distribution network lines and the distribution network access nodes corresponding to the local power grid topology network are obtained from the distribution network production management system.

[0068] Furthermore, after obtaining the distribution network line in the planned power outage work order and the distribution network access node of the generator car in the power supply protection work order of the generator car, by traversing the distribution network line, it is identified whether the distribution network access node belongs to the node corresponding to a certain standby switch position in the distribution network line. When it is identified that the distribution network access node is the node corresponding to the certain standby switch position, a mapping relationship between the power supply protection work order of the generator car currently being matched and the planned power outage work order is constructed, so as to match the planned power outage work order to its corresponding power supply protection work order of the generator car according to the mapping relationship. That is, the power supply protection work order of the generator car corresponds to a planned power outage work order.

[0069] Step 303: Obtain the substation number corresponding to the user's power outage event, and obtain the power grid topology route where the substation number is located from the distribution network GIS system.

[0070] In this embodiment, the steps are mainly as follows: responding to reported user power outage events to identify the address information input by the user in real time, and then traversing and matching the keywords in the address information with the keywords in the standard address library, and then obtaining the standard address corresponding to the address information and the substation number associated with the standard address; according to the power grid topology network, calling the GIS service of the distribution network, inputting the substation number, and obtaining the local power grid topology network where the user power outage event is located, and obtaining the correspondence between the substation-line-power equipment-substation number in the local power grid topology network from the distribution network production management system, so as to finally reach the power grid topology route in the user power outage event according to the correspondence.

[0071] Specifically, when a power outage occurs in a certain area, the power outage information collection terminal will collect the power outage events reported by users in real time, and locate the current reporting user after obtaining the power outage event to identify the power equipment where the power outage occurred. Specifically, in the positioning process, it is first necessary to parse the address where the power outage event reported by the user occurred, and determine the area number where the user is located, so as to reduce the time for equipment positioning, thereby improving the efficiency of power outage analysis.

[0072] Preferably, in the process of address resolution, since the address information uploaded by the user may be missing or the address may be expressed differently, in this case, the present embodiment needs to convert the address uploaded by the user into a standard address for matching the station area number. Optionally, in the process of matching the standard address, since the standard address is often structured information, and the address uploaded by the customer is relatively random and unstructured, it is necessary to translate the unstructured information uploaded by the user into structured information. In this regard, in some ways of the present embodiment, an address resolution positioning model is selected to be constructed to use administrative divisions, standard addresses, customer numbers, customer names, contact information and other data to comprehensively compile and analyze the customer address, accurately determine the customer location, and provide support for fault analysis, accurate dispatching, geographic distribution and other services. Specifically, in this embodiment, according to the order of regional hierarchical division, through top-to-bottom layer-by-layer retrieval and comparison, each level of geographic information is identified and extracted from the unstructured work order information, and after supplementation and improvement, structured address information that meets the standard requirements is constructed. For example, the address uploaded by the user is Baiyun, Guangzhou, and the model is supplemented and improved to form Baiyun District, Guangzhou City, Guangdong Province.

[0073] Furthermore, after parsing the address information uploaded by the user, the keywords in the address information are matched with the standard address library by keyword traversal, and the matching methods include but are not limited to pictographic matching and pinyin matching. After the matching is completed, the standard address information can be matched with the data of the standard address library of the substation area, and the obtained list of accurately matched substation areas is analyzed to determine the substation area number. In this embodiment, the matched structured standard address is matched with the data of the standard address library of the substation area in the marketing business application system to obtain the substation area including the user address and the substation area number corresponding to the substation area.

[0074] Step 304: Based on the grid topology route and the distribution network outage line, obtain the target planned power outage work order corresponding to the user power outage event from multiple first planned power outage work orders and obtain the target power generation vehicle power protection work order corresponding to the target planned power outage work order according to the association relationship.

[0075] In this embodiment, the steps are mainly as follows: starting from the distribution network outage line, searching for each topological branch connected to the distribution network outage line; for each topological branch of the distribution network outage line, if the searched device is a bus, determining whether the voltage level of the bus is different from the voltage level of the power station to which the bus belongs, if different, stopping the search for the corresponding topological branch, and using the previous device of the bus as the power source, if the same, continuing the search; if the searched device is a distribution transformer, stopping the search for the corresponding topological branch; if the searched device is a normally open contact switch, determining whether the normally open contact switch is in the closed switch list, if so, continuing the search, if not, stopping the search for the corresponding topological branch; if the searched device is an electrical equipment other than a bus, a transformer or a normally open contact switch, continuing the search. After all transformers corresponding to the distribution network power outage lines are obtained through search, a grid connectivity analysis is performed on each of the transformers according to the distribution network power outage lines to obtain all distribution network power outage lines involved in the planned power outage work order, and the route overlap of the distribution network power outage lines and the grid topology lines is calculated to obtain the planned power outage work order corresponding to the user power outage event from multiple of the first planned power outage work orders and obtain the power supply vehicle protection work order corresponding to the planned power outage work order according to the association relationship.

[0076] Specifically, the initial query conditions are constructed according to the user input data to prepare for topology tracking. The necessary conditions are the power outage lines in the distribution network, and the optional conditions are the list of switches that need to be disconnected and the list of switches that need to be closed in the power grid. The various input devices are power grid devices selected and specified by the mouse on the map in the graphical interface system. According to the obtained topological search source point device type and device ID, the starting point device for analysis can be found in the database, and the list of switches that need to be disconnected and the list of switches that need to be closed can also be queried. During the tracing process, single-source breadth tracing is performed on the device topology network starting from each device in the power outage line of the distribution network to be shut down; during the tracing process, all power supplies supplying each device in the power outage line of the distribution network to be shut down are collected as search sources for subsequent steps, and all encountered distribution transformers are collected; during the tracing process, a judgment is made for each searched device to decide whether to record the device, continue to search for other devices connected to the device, or stop subsequent searches for the device, as follows: If the searched device is a bus, and the voltage level of the bus is different from the voltage level of the power station to which the bus belongs, it means that the bus is the medium-voltage side bus of the substation and is the power source of the current branch. At this time, the branch will no longer be searched, and the previous device of the bus will be used as the power source. Record it and add it to the power supply list. If the voltage level of the bus is the same as the voltage level of the power station to which the bus belongs, the bus is a distribution station. Note that the previous device of the bus on the power supply link is used as the power source here, because other outgoing lines of the bus may cause the tracking to other distribution networks, affecting the results. If the searched device is a transformer, record the distribution transformer and add it to the transformer list, and the search branch will not continue. If the searched device is a switch, and it is a normally open contact switch: if the switch is in the closed switch list, the tracking path should be considered as unobstructed and continue to move forward without direction; otherwise, as a normally open switch, the search branch will not continue. If the searched device does not meet the above conditions or is other power equipment, continue to search. During the tracking process, read the corresponding attributes of the device according to the device type, perform corresponding operations on the devices that meet the conditions, and decide whether the topology branch needs to continue; through the judgment of different device types as above, if the branch needs to continue tracking, add other devices connected to the device to the list to be tracked, and then take out a device from the list to be tracked for judgment; continue tracking repeatedly until there is no device in the list of devices to be tracked. When tracing in this step, all the devices encountered are those that can be connected together through switches starting from each device in the power outage line of the distribution network to be shut down. All power sources supplying power to each device in the power outage line of the distribution network to be shut down should be collected as search sources for subsequent steps. In addition, the distribution transformers encountered during tracing are all possible power outage devices, and all distribution transformers should be collected.Furthermore, after obtaining the information of the power equipment involved in the power outage event, according to the topological relationship information of the power grid, the related power equipment is iterated downward step by step from the known power outage transformer until the power terminal equipment in the power grid is found. The power equipment involved in the power outage event, such as transformer a, transformer b, and transformer c, can be obtained by analyzing and statistically analyzing the power outage data information. Starting from these known power equipment, the connectivity analysis is performed according to the topological relationship of the power grid, and the related power equipment is iterated downward step by step until the power terminal equipment in the power grid is found.

[0077] Step 305: Obtain the power outage information and power protection information in the target planned power outage work order and the target power generation vehicle power protection work order.

[0078] In this embodiment, the steps mainly include: performing data conversion and typo correction on the acquired target planned power outage work order and the target power supply work order for the power generation vehicle, respectively, so as to remove the erroneous information in the work order and improve the accuracy of information extraction; then, marking the power outage information description text and the power supply information description text in the work order sample, training the word vector through word embedding technology, and then obtaining the word vector matrix, training the pre-constructed deep learning model according to the matrix and the description text, locating the starting position for describing the power outage information and the power supply information in the work order through the trained deep learning model, and then extracting the corresponding power outage information and the power supply information from the target planned power outage work order and the target power supply work order for the power generation vehicle according to the starting position.

[0079] Specifically, in this embodiment, the sample is labeled. The historical work order is obtained, and the power outage information description text and the power protection information description text in the work order sample are labeled to obtain the labeled sample, and B represents the beginning of the text, I represents the middle of the text, and E represents the technology of the text; O represents the non-power outage information text and the non-power protection information text. The word embedding WordEmbedding technology is used to train the word vector to obtain the word vector matrix. Millions (for example, 5 million) of historical work order text data of the power system are collected, and the word vector is trained using the CBOW model in the word2Vec algorithm. Among them, there are many ways to vectorize text. Compared with methods such as Tf-idf and bag of words models, the WordEmbedding of this embodiment can effectively capture the contextual relationship of words, make full use of massive data, and achieve better model effects. The advantage of this embodiment is that the word vector matrix traditionally used in WordEmbedding is obtained by training texts in general fields, and the effect is poor when applied to the text model in the power field; while the word vector matrix of this embodiment is obtained by training texts in the power field, and better accuracy and generalization ability will be achieved when applied.

[0080] Next, the BiLSTM+CRF algorithm is used to train the named entity recognition model using the labeled samples and word vector matrix, and the trained named entity recognition model is used to identify power outage information and power protection information. The named entity recognition model includes: a data input layer, where the input text becomes sequence data after word segmentation, and the trained word vector matrix is ​​converted into corresponding vectors at the data input layer, and input into the next layer for feature extraction by the BiLSTM model; a feature extraction layer, where the BiLSTM model is constructed, and the feature representation of the observed sequence is automatically extracted, and input into the next layer for CRF model training; a model training layer, where the features transmitted from the feature extraction layer are input, and the label judgment of each text node is output, and the parameters are adjusted to train the CRF model until convergence.

[0081] Step 306: Match the SMS template corresponding to the power outage information to generate a power outage analysis SMS to reply to the user's power outage event based on the power outage information, the power protection information and the SMS template.

[0082] In this embodiment, the steps mainly include: determining the power outage type based on the power outage information; matching the SMS template corresponding to the power outage type; obtaining the configuration information of the SMS template, and adding the power outage information and the power protection information to the SMS template according to the configuration information to form a reply SMS; and sending the reply SMS to the user's power outage event.

[0083] The power outage cause category corresponding to the power outage information in the planned power outage work order is obtained through the constructed work order classification model; wherein, the categories include guaranteeing all power consumption and guaranteeing partial power consumption. Different power outage cause categories correspond to different SMS templates; for example, the SMS template corresponding to guaranteeing partial power consumption has a pre-set and fixed "Do not use high-power electrical appliances during the power protection period", while the SMS category corresponding to guaranteeing all power consumption does not exist. Then, after calling the corresponding SMS template, the SMS template is configured and parsed, and the display area and display size of the power outage information and the power protection information in the SMS template are clarified, and then the power outage information and the power protection information are added to the SMS template according to the display area and the display size, and a power outage information analysis SMS is generated. Then, when replying to the power outage information analysis SMS, the contact information of all users affected by the power outage can be obtained, and the power outage information analysis SMS can be sent according to the contact information. The contact information of the user who reported the power outage time can also be obtained to send the power outage information analysis SMS according to the contact information.

[0084] The present invention discloses a power outage management and analysis method for power supply protection of a power generation vehicle. First, for the power outage moment in the reported user power outage event, a plurality of first planned power outage work orders and a plurality of first power generation vehicle power supply protection work orders associated with the power outage moment are obtained from a database storing approved work orders, so as to reduce the amount of work order data required to be processed when matching the corresponding work orders, thereby improving the efficiency of obtaining power outage information and power supply protection information. Further, in order to accurately locate the power outage work order corresponding to the power outage event and the power generation vehicle work order used to protect the power outage event, the power generation vehicle power supply protection work order and the first planned power outage work order are first parsed, so as to complete the association between power outage and power supply protection according to the power outage line and distribution network access node corresponding to the power generation vehicle power supply work order and the planned power outage work order, and then use the association to achieve accurate correspondence between power supply protection and power outage. Next, in order to accurately obtain the power outage information and power supply protection information corresponding to the power outage event, the power outage event is located, and then the power grid topology route of the power outage event and the power outage line of the distribution network are matched. After obtaining the corresponding planned power outage work order and the power supply protection work order of the generator vehicle, the corresponding power outage information and power supply protection information are obtained from the planned power outage work order and the power supply protection work order of the generator vehicle, and the corresponding SMS template is called according to the power outage information to generate an accurate reply SMS to meet the user's power outage consultation needs.

[0085] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
