Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power outage management, in particular to a power outage management analysis method and system based on power generation vehicle power preservation. BACKGROUND

[0002] With the development of science and technology and the progress of society, people's demand for power and power quality is increasing day by day. Once the power grid accident causes large-area power outage, it will not only cause inconvenience to people's daily life, but also affect the stability of society and the development of economy. In order to maintain the normal operation of the distribution network, the distribution network management department will regularly overhaul the distribution network according to the pre-prepared power outage plan to ensure the normal work of the distribution network.

[0003] In the process of power outage for overhaul of the distribution network, users often call the power management department to obtain specific power restoration and power outage information due to sudden power outage without receiving power outage information. For this reason, the prior art generates a power outage analysis report for the user by manually querying the corresponding power outage plan, but due to the efficiency of manual query, the power outage analysis cannot be performed in time.

[0004] At the same time, the technology of generating power outage information based on power outage plan does not consider power preservation. For example, in order to reduce the social impact of power outage, some areas will use power generation vehicles and other power preservation equipment to replace the power supply equipment being repaired to supply power. As a result, only a short power outage will occur in this part of the area, resulting in a discrepancy between the actual power outage of the user and the power outage in the power outage information, and thus the power outage information received by the user is inaccurate. SUMMARY

[0005] In order to solve the above technical problems, the present application discloses a power outage management analysis method and system based on power generation vehicle power preservation, which is used to improve the efficiency and accuracy of power outage management analysis.

[0006] In order to achieve the above purpose, the present application discloses a power outage management analysis method based on power generation vehicle power preservation, comprising:

[0007] Based on the request time of the power outage event, a plurality of planned power outage work orders and a plurality of power generation vehicle power preservation work orders are obtained;

[0008] The power distribution network outage line of the planned power outage work order and the power distribution network access node of the power generation vehicle in the power generation vehicle power preservation work order are obtained to establish a mapping relationship between the planned power outage work order and the power generation vehicle power preservation work order;

[0009] The power outage event is in the power grid topology route, and the target planned power outage work order is selected from a plurality of the planned power outage work orders according to the power grid topology route and the power distribution network power outage line; wherein, the request address of the power outage event is obtained to obtain the power grid topology route where the power outage event is located from the power distribution network GIS system according to the request address; each topology branch of the power distribution network power outage line is searched to obtain the power outage topology route corresponding to the power distribution network power outage line; the route coincidence degree of the power grid topology route and the power outage topology route is obtained to select the target planned power outage work order from a plurality of the planned power outage work orders according to the route coincidence degree; wherein, the power distribution network power outage line is taken as the starting point, and each topology branch connected with the power distribution network power outage line is searched; for any topology branch; when the searched device is a bus, it is judged whether the voltage level of the bus is the same as the voltage level of the power station to which the bus belongs, if not, the search of the topology branch is stopped, and the previous device of the bus is taken as the power supply, if the same, the search is continued; when the searched device is a distribution transformer, the search of the corresponding topology branch is stopped; if the searched device is a normally open tie switch, it is judged whether the normally open tie switch is in the closed switch list, if yes, the search is continued, if not, the search of the corresponding topology branch is stopped; if the searched device is a power device other than the bus, the transformer or the normally open tie switch, the search is continued; when a plurality of transformers corresponding to the power distribution network power outage line are obtained based on the search, the power grid connectivity analysis is performed on each of the transformers according to the power distribution network power outage line to obtain the power outage topology route corresponding to the power distribution network power outage line;

[0010] The target planned power outage work order corresponding to the target generating car power protection work order is determined based on the mapping relationship, and the power outage information corresponding to the target planned power outage work order and the power protection information in the target generating car power protection work order are obtained;

[0011] The power outage analysis report corresponding to the power outage event is generated based on the power outage information and the power protection information.

[0012] The power outage management analysis method based on the power generation vehicle power protection disclosed in the application obtains work orders based on the request time of the power outage event to reduce the processing amount of the work orders and improve the analysis efficiency. Among them, the planned power outage work order and the power generation vehicle power protection work order are obtained at the same time to improve the accuracy of the power outage analysis by combining the planned power outage and power protection. Secondly, in the process of power outage analysis, the planned power outage work order and the power generation vehicle power protection work order are one-to-one corresponding by using the power distribution network power outage line and the power distribution network access node of the power generation vehicle, so as to obtain the corresponding power outage information and power protection information according to the corresponding relationship, thereby reducing the processing amount of the power 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 distribution network power outage line 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 protection information corresponding to the power outage information, thereby improving the accuracy of the power outage analysis. Finally, the power outage analysis report corresponding to the power outage event is generated based on the obtained power outage information and power protection information, thereby improving the efficiency and accuracy of the power outage management analysis.

[0013] Among them, each topology branch of the power distribution network power outage line is searched to determine the power outage range caused by the power distribution network power outage line, the efficiency of the power outage range retrieval is improved by using the searched power outage topology route, and then the accuracy of the target planned power outage work order screening is ensured based on the power grid topology route where the power outage event is located and the power outage topology route, thereby improving the accuracy of the power outage analysis. When searching the multiple topology branches connected with the power distribution network power outage line to determine the power outage range, the search progress of each topology branch is determined by setting the type of the search equipment, thereby improving the search efficiency and the efficiency of the power outage analysis. Among them, after learning the multiple transformers corresponding to the power distribution network power outage line based on the search, the power grid connectivity analysis is performed on each transformer corresponding to the power distribution network power outage line according to the power distribution network power outage line, so as to determine the power outage topology route corresponding to the power distribution network power outage line, thereby improving the accuracy of the power outage topology route search and the accuracy of the power outage analysis.

[0014] As a preferred example, the request time based on the power outage event is used to obtain multiple planned power outage work orders and multiple power generation vehicle power protection work orders, including:

[0015] For any planned power outage work order and any power generation vehicle power protection work order;

[0016] Extract the planned power outage time in the planned power outage work order and the planned power protection time in the power generation vehicle power protection work order;

[0017] Obtain the power outage difference between the request time and the planned power outage time and the power protection difference between the request time and the planned power protection time;

[0018] when the power-off difference value is less than or equal to a preset time threshold, taking the planned power-off work order as a planned power-off work order corresponding to the power-off event;

[0019] when the power-off difference value is less than or equal to the time threshold, taking the power-off work order of the power generation vehicle as a power-off work order of the power generation vehicle corresponding to the power-off event.

[0020] In the above scheme, in order to reduce the processing amount of the work order, the target work order is obtained from a small range of work orders, thereby improving the efficiency of power-off analysis. The planned power-off time and the planned power-off time in each work order are used to filter the work orders within a certain range at the current request time, which not only ensures the accuracy of the work order acquisition, but also reduces the number of work orders, thereby improving the efficiency and accuracy of power-off analysis.

[0021] As a preferred example, the request time based on the power-off event is used to obtain a plurality of planned power-off work orders and a plurality of power-off work orders of the power generation vehicle, and further comprises:

[0022] obtaining a plurality of initial planned power-off work orders and a plurality of initial power-off work orders of the power generation vehicle from a database storing the work orders;

[0023] obtaining the power-off approval state of the initial planned power-off work order and the power-off approval state of the initial power-off work order of the power generation vehicle;

[0024] for any initial planned power-off work order and any initial power-off work order of the power generation vehicle;

[0025] when the power-off approval state of the initial planned power-off work order is passed, taking the initial planned power-off work order as the planned power-off work order;

[0026] when the power-off approval state of the initial power-off work order of the power generation vehicle is passed, taking the initial power-off work order of the power generation vehicle as the power-off work order of the power generation vehicle.

[0027] In the above scheme, based on the fact that the work order formulation process may involve revocation, modification and unreasonable situations, which may result in multiple corresponding work orders for the same planned power-off event. At this time, in order to avoid the acquisition of useless work orders, the eligibility of the work order can be verified by using the approval state of each work order, and then the subsequent power-off information and power-off information are obtained by only acquiring the work order with the approval state passed, thereby improving the efficiency of power-off analysis.

[0028] As a preferred example, the power distribution network power-off line of the planned power-off work order and the power distribution network access node of the power generation vehicle in the power-off work order of the power generation vehicle are obtained to establish the mapping relationship between the planned power-off work order and the power-off work order of the power generation vehicle, comprising:

[0029] extracting a planned power-off line in the planned power-off work order and a power generation position corresponding to the power generation vehicle in the power generation vehicle power-off work order;

[0030] obtaining a power grid outage line corresponding to the planned power-off line and a power grid access node corresponding to the power generation position from a power grid GIS system according to the planned power-off line and the power generation position;

[0031] matching the power grid access node and the power grid outage line to obtain a mapping relationship between the planned power-off work order and the power generation vehicle power-off work order.

[0032] In the above scheme, when power generation vehicles are used for power protection, the devices powered by the power generation vehicles are in a power-off state, that is, the planned power-off work order and the power generation vehicle power-off work order are in a corresponding relationship. At this time, in order to improve the efficiency of power-off analysis, the matching degree of the planned power-off line and the power grid access node is used to obtain the corresponding relationship between the planned power-off work order and the power generation vehicle power-off work order, so as to reduce the processing quantity of the power generation vehicle power-off work order according to the corresponding relationship, and further improve the efficiency of power-off analysis.

[0033] As a preferred example, the matching of the power grid access node and the power grid outage line to obtain the mapping relationship between the planned power-off work order and the power generation vehicle power-off work order comprises:

[0034] for any planned power-off work order;

[0035] traversing the power grid outage line corresponding to the planned power-off work order to obtain a switch access node corresponding to each standby switch position;

[0036] for any power generation vehicle power-off work order;

[0037] when the power grid access node of the power generation vehicle power-off work order is consistent with the switch access node, a mapping relationship between the power generation vehicle power-off work order and the planned power-off work order is established.

[0038] In the above scheme, the power generation vehicle often accesses a node at a standby switch position in a line for power supply. Therefore, when the planned power-off work order and the power generation vehicle power-off work order are matched, the node corresponding to the standby switch position in the power grid outage line is used for matching, which can improve the efficiency and accuracy of matching, and further ensure the accuracy of power protection information acquisition.

[0039] As a preferred example, the request address of the power-off event is obtained from the power grid GIS system according to the request address to obtain a power grid topology route where the power-off event is located, and the request address comprises:

[0040] analyzing the power-off event to obtain a user input address;

[0041] extracting a keyword in the user input address, and matching the keyword with a preset standard keyword in a standard address library to obtain a standard address corresponding to the user input address;

[0042] obtaining a transformer area number associated with the standard address, and calling a GIS service of a power distribution network to obtain a local power grid topology network in which the transformer area number is located;

[0043] obtaining a correspondence relationship among substations, lines, power equipment and transformer area numbers in the local power grid topology network, so as to obtain a power grid topology route in which the power failure event is located according to the correspondence relationship.

[0044] In the above scheme, in the process of positioning, the transformer area number in which the user is located is determined based on the user input address, so as to reduce the time of event positioning and improve the efficiency of power failure analysis. When obtaining the power grid topology route, the GIS service of the power distribution network and the correspondence relationship among substations, lines, power equipment and transformer area numbers in the local power grid topology network are used to ensure the efficiency and accuracy of obtaining the power grid topology route.

[0045] As a preferred example, the determining of the target planned power failure work order corresponding to the target power generation vehicle power protection work order based on the mapping relationship, and the obtaining of the power failure information corresponding to the target planned power failure work order and the power protection information in the target power generation vehicle power protection work order, include:

[0046] respectively performing data conversion and error correction on the target planned power failure work order and the target power generation vehicle power protection work order to obtain a corrected planned power failure work order and a corrected power generation vehicle power protection work order;

[0047] respectively inputting the corrected planned power failure work order and the corrected power generation vehicle power protection work order into a pre-constructed deep learning model to locate a power failure text position of the corrected planned power failure work order and a power protection text position of the corrected power generation vehicle power protection work order;

[0048] extracting power failure information of the corrected planned power failure work order based on the power failure text position;

[0049] extracting power protection information of the corrected power generation vehicle power protection work order based on the power protection text position.

[0050] In the above scheme, the obtained planned power outage work order and the power generation vehicle power protection work order are respectively subjected to data conversion and error correction to remove the error information in the work order and improve the accuracy of information extraction. Then, the starting position of the power outage information and the power protection information in the work order is located through the trained deep learning model, and then the corresponding power outage information and power protection information are extracted from the planned power outage work order and the power generation vehicle power protection work order according to the starting position, so as to improve the accuracy and efficiency of information acquisition, and further improve the efficiency and accuracy of power outage analysis.

[0051] As a preferred example, the power outage analysis report corresponding to the power outage event is generated based on the power outage information and the power protection information, including:

[0052] determining the power outage type according to the power outage information to match the report template corresponding to the power outage type;

[0053] obtaining the configuration information of the report template to add the power outage information and the power protection information to the report template according to the configuration information to form the power outage analysis report.

[0054] In the above scheme, the report template corresponding to the power outage information is matched to generate the power outage analysis report containing the complete information of the power outage information and the power protection information by using the report template, so as to ensure that the user obtains the accurate power outage analysis report.

[0055] On the other hand, the application discloses a power outage management 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.

[0056] The work order extraction module is used to obtain a plurality of planned power outage work orders and a plurality of power generation vehicle power protection work orders based on the request time of the power outage event.

[0057] The relationship mapping module is used to obtain the power distribution network power outage line of the planned power outage work order and the power distribution network access node of the power generation vehicle in the power generation vehicle power protection work order to establish the mapping relationship between the planned power outage work order and the power generation vehicle power protection work order.

[0058] The work order screening module is configured to obtain a power grid topology route where the power failure event is located, and select a target planned power failure work order from a plurality of the planned power failure work orders according to the power grid topology route and the power distribution network power failure line; wherein, a request address of the power failure event is obtained to obtain the power grid topology route where the power failure event is located from a power distribution network GIS system according to the request address; each topology branch of the power distribution network power failure line is searched to obtain a power failure topology route corresponding to the power distribution network power failure line; a route coincidence degree of the power grid topology route and the power failure topology route is obtained to select the target planned power failure work order from the plurality of the planned power failure work orders according to the route coincidence degree; wherein, the power distribution network power failure line is taken as a starting point, and each topology branch connected to the power distribution network power failure line is searched; for any topology branch; when the searched device is a bus, it is judged whether the voltage level of the bus is the same as the voltage level of the power station to which the bus belongs, if not, the search of the topology branch is stopped, and the previous device of the bus is taken as a power supply, if yes, the search is continued; when the searched device is a distribution transformer, the search of the corresponding topology branch is stopped; if the searched device is a normally open tie switch, it is judged whether the normally open tie switch is in a closed switch list, if yes, the search is continued, if not, the search of the corresponding topology branch is stopped; if the searched device is a power device other than the bus, the transformer or the normally open tie switch, the search is continued; when a plurality of transformers corresponding to the power distribution network power failure line are obtained based on the search, power grid connectivity analysis is performed on each of the transformers according to the power distribution network power failure line to obtain the power failure topology route corresponding to the power distribution network power failure line;

[0065] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0066] Embodiment one

[0067] The embodiment discloses a power outage management analysis method based on power generation car power preservation, which is used to improve the efficiency and accuracy of power outage management analysis. Specifically, the specific implementation process of the power outage management analysis method is shown in Figure 1 , mainly including steps 101 to 105, which are mainly as follows.

[0068] Step 101: Obtain a plurality of planned power outage work orders and a plurality of power generation vehicle power preservation work orders based on a request time of the power outage event.

[0069] Step 102: Obtain a power distribution network outage line of the planned power outage work order and a power distribution network access node of the power generation vehicle in the power generation vehicle power preservation work order to establish a mapping relationship between the planned power outage work order and the power generation vehicle power preservation work order.

[0070] Step 103: Obtain a power grid topology route where the power outage event is located, and select a target planned power outage work order from a plurality of the planned power outage work orders according to the power grid topology route and the power distribution network outage line.

[0071] Step 104: Determine a target power generation vehicle power preservation work order corresponding to the target planned power outage work order based on the mapping relationship, and obtain outage information corresponding to the target planned power outage work order and power preservation information in the target power generation vehicle power preservation work order.

[0072] Step 105: Generate a power outage analysis report corresponding to the power outage event based on the outage information and the power preservation information.

[0073] In some embodiments of the present embodiment, when extracting work orders, the following steps are preferably taken to improve the efficiency and accuracy of work order extraction. Specifically, the steps are as follows:

[0074] Step 1011: For any planned power outage work order and any power generation vehicle power preservation work order, extract a planned power outage time in the planned power outage work order and a planned power preservation time in the power generation vehicle power preservation work order.

[0075] Step 1012: Obtain a power outage difference value between the request time and the planned power outage time and a power preservation difference value between the request time and the planned power preservation time.

[0076] Step 1013: When the power outage difference value is less than or equal to a preset time threshold, the planned power outage work order is taken as a planned power outage work order corresponding to the power outage event.

[0077] Step 1014: When the power preservation difference value is less than or equal to the time threshold, the power generation vehicle power preservation work order is taken as a power generation vehicle power preservation work order corresponding to the power outage event.

[0078] In the present embodiment, the above steps are used to reduce the processing amount of work orders, so as to obtain target work orders from a small range of work orders and improve the efficiency of power outage analysis. By using the planned power outage time and the planned power preservation time in each work order, work orders within a certain range at the current request time are screened out, which not only ensures the accuracy of work order extraction, but also reduces the number of work orders, thereby improving the efficiency and accuracy of power outage analysis.

[0079] In some embodiments of the present application, when the steps 1011-1014 are performed to obtain the work order, the following steps can be used to establish the criteria for obtaining the work order, so as to further reduce the processing amount of the work order and improve the efficiency of obtaining the work order according to the criteria. Specifically, the steps are as follows:

[0080] Step 1015: Obtain a plurality of initial planned outage work orders and a plurality of initial generator car protection work orders from a database storing the work orders;

[0081] Step 1016: Obtain the outage approval status of the initial planned outage work order and the protection approval status of the initial generator car protection work order;

[0082] Step 1017: For any initial planned outage work order and any initial generator car protection work order, when the outage approval status of the initial planned outage work order is passed, the initial planned outage work order is taken as the planned outage work order;

[0083] Step 1018: When the protection approval status of the initial generator car protection work order is passed, the initial generator car protection work order is taken as the generator car protection work order.

[0084] In the present application, the above steps are based on the fact that during the establishment of the work order, there may be situations such as revocation, modification and unreasonableness, which may result in multiple work orders corresponding to the same planned 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 a passed approval status are acquired for subsequent acquisition of outage information and protection information, thereby improving the efficiency of outage analysis.

[0085] In some embodiments of the present application, when the step 102 is performed to establish the mapping relationship between the planned outage work order and the generator car protection work order, the following steps are preferably used to improve the efficiency and accuracy of work order matching, and further improve the efficiency and accuracy of outage analysis. Specifically, the steps include:

[0086] Step 1021: Extract the planned outage line in the planned outage work order and the generator position corresponding to the generator car in the generator car protection work order;

[0087] Step 1022: Obtain the distribution network outage line corresponding to the planned outage line and the distribution network access node corresponding to the generator position from the distribution network GIS system according to the planned outage line and the generator position;

[0088] Step 1023: Match the distribution network access node and the distribution network outage line to obtain the mapping relationship between the planned outage work order and the generator car protection work order.

[0089] In the embodiment, when the power generation vehicle is used to supply power according to the power supply plan, the equipment supplied by the power generation vehicle is in a power-off state, that is, the planned power-off work order and the power generation vehicle power supply work order are in a corresponding relationship. In order to improve the efficiency of the power-off analysis, the matching degree of the planned power-off line and the power distribution network access node is used to obtain the corresponding relationship between the planned power-off work order and the power generation vehicle power supply work order, so as to reduce the processing quantity of the power generation vehicle power supply work order according to the corresponding relationship, and further improve the efficiency of the power-off analysis.

[0090] In some embodiments of the embodiment, the step 1023 matches the power distribution network access node and the power distribution network power-off line, preferably the following steps are used to match the line and the node, so as to improve the accuracy of the matching and ensure the accuracy of the power-off analysis. Specifically, the step includes:

[0091] Step 10231: for any planned power-off work order, traversing the power distribution network power-off line corresponding to the planned power-off work order, obtaining the switch access node corresponding to each standby switch position;

[0092] Step 10232: for any power generation vehicle power supply work order, when the power distribution network access node of the power generation vehicle power supply work order is consistent with the switch access node, the mapping relationship between the power generation vehicle power supply work order and the planned power-off work order is established.

[0093] In the embodiment, the power generation vehicle often supplies power based on the node where the standby switch position of the line is located. Therefore, when the planned power-off work order and the power generation vehicle power supply work order are matched, the node corresponding to the standby switch position in the power distribution network power-off line is used for matching, which can improve the efficiency and accuracy of the matching, and further ensure the accuracy of the power supply information acquisition.

[0094] In some embodiments of the embodiment, the step 103 determines the target planned power-off work order and the target power generation vehicle power supply work order corresponding to the power-off event based on the following steps, so as to improve the efficiency and accuracy of the power-off analysis. Specifically, the step includes:

[0095] Step 1031: obtaining the request address of the power-off event, so as to obtain the power grid topology route where the power-off event is located from the power distribution network GIS system according to the request address;

[0096] Step 1032: searching each topology branch of the power distribution network power-off line, and obtaining the power-off topology route corresponding to the power distribution network power-off line;

[0097] Step 1033: obtaining the route coincidence degree of the power grid topology route and the power-off topology route, so as to select the target planned power-off work order from a plurality of planned power-off work orders according to the route coincidence degree.

[0098] In the embodiment, the above step searches each topology branch of the power distribution network outage line to determine the outage range caused by the power distribution network outage line, improves the efficiency of outage range retrieval by using the searched outage topology line, and then ensures the accuracy of target planned outage work order screening based on the power grid topology line where the outage event is located and the outage topology line, thereby improving the accuracy of outage analysis.

[0099] In some embodiments of the embodiment, the step 1031 preferably performs the following steps to obtain the power grid topology line to improve the efficiency and accuracy of outage analysis. Specifically, the steps include:

[0100] Step 10311: Analyzing the outage event to obtain a user input address;

[0101] Step 10312: Extracting a keyword from the user input address and matching the keyword with a preset standard keyword in a standard address library to obtain a standard address corresponding to the user input address;

[0102] Step 10313: Obtaining a transformer area number associated with the standard address and calling a GIS service of the power distribution network to obtain a local power grid topology network where the transformer area number is located;

[0103] Step 10314: Obtaining a correspondence relationship between a transformer station, a line, a power device, and a transformer area number in the local power grid topology network to obtain a power grid topology line where the outage event is located according to the correspondence relationship.

[0104] In the embodiment, in the process of positioning, the user's transformer area number is first determined based on the user input address to reduce the time of event positioning and improve the efficiency of outage analysis. When obtaining the power grid topology line, the GIS service of the power distribution network and the correspondence relationship between the transformer station, the line, the power device, and the transformer area number in the local power grid topology network are used to ensure the efficiency and accuracy of obtaining the power grid topology line.

[0105] In some embodiments of the embodiment, the step 1032 preferably performs the following steps to search the topology line to improve the efficiency and accuracy of searching, thereby improving the efficiency and accuracy of outage analysis. Specifically, the steps include:

[0106] Step 10321: Searching each topology branch connected to the power distribution network outage line from the power distribution network outage line as a starting point;

[0107] Step 10322: for any of the topological branches; when the searched device is a bus, judging whether the voltage level of the bus is the same as the voltage level of the power station to which the bus belongs, if not, stopping the search of the topological branch, and taking the previous device of the bus as the power supply, if yes, continuing the search; when the searched device is a distribution transformer, stopping the search of the corresponding topological branch; if the searched device is a normally open tie switch, judging whether the normally open tie switch is in the list of closed switches, if yes, continuing the search, if not, stopping the search of the corresponding topological branch; if the searched device is a power device other than a bus, a transformer or a normally open tie switch, continuing the search;

[0108] Step 10323: after obtaining the multiple transformers corresponding to the power failure line of the distribution network based on the search, performing power grid connectivity analysis on each of the transformers according to the power failure line of the distribution network, to obtain the power failure topology route corresponding to the power failure line of the distribution network.

[0109] In the embodiment, when searching for multiple topological branches connected to the power failure line of the distribution network to determine the power failure range, the search efficiency is improved by setting the type of the searched device and determining the search progress of each topological branch, thereby improving the efficiency of the power failure analysis. After obtaining the multiple transformers corresponding to the power failure line of the distribution network based on the search, the power grid connectivity analysis is performed on each of the transformers according to the power failure line of the distribution network, to determine the power failure topology route corresponding to the power failure line of the distribution network, thereby improving the accuracy of the search of the power failure topology route and the accuracy of the power failure analysis.

[0110] In some embodiments of the present embodiment, the step 104 extracts the power failure information and the power preservation information based on the following steps, to improve the efficiency and accuracy of the extraction, and thereby improve the efficiency and accuracy of the power failure analysis. Specifically, the step includes:

[0119] In the embodiment, the above-mentioned steps match the report template corresponding to the power-off information to generate a power-off analysis report containing complete information of the power-off information and the power-on information by using the report template, so as to ensure that the user obtains an accurate power-off analysis report.

[0120] On the other hand, the present application also discloses a power-off management analysis system based on power car power-on. The specific structure and composition of the power-off management analysis system are described in detail in the Figure 2 , which comprises 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-off analysis module 205.

[0121] The work order extraction module 201 is used to obtain a plurality of planned power-off work orders and a plurality of power car power-on work orders based on the request time of the power-off event.

[0122] The relationship mapping module 202 is used to obtain the power distribution network power-off line of the planned power-off work order and the power distribution network access node of the power car in the power car power-on work order to establish the mapping relationship between the planned power-off work order and the power car power-on work order.

[0123] The work order screening module 203 is configured to obtain a power grid topology route where the power failure event is located, and select a target planned power failure work order from a plurality of the planned power failure work orders according to the power grid topology route and the power distribution network power failure line; wherein, a request address of the power failure event is obtained to obtain the power grid topology route where the power failure event is located from a power distribution network GIS system according to the request address; each topology branch of the power distribution network power failure line is searched to obtain a power failure topology route corresponding to the power distribution network power failure line; a route coincidence degree of the power grid topology route and the power failure topology route is obtained to select the target planned power failure work order from the plurality of the planned power failure work orders according to the route coincidence degree; wherein, the power distribution network power failure line is taken as a starting point, and each topology branch connected with the power distribution network power failure line is searched; for any topology branch; when the searched device is a bus, it is judged whether the voltage level of the bus is same as the voltage level of the power station to which the bus belongs, if not, the search of the topology branch is stopped, and a previous device of the bus is taken as a power supply, if yes, the search is continued; when the searched device is a distribution transformer, the search of the corresponding topology branch is stopped; if the searched device is a normally open tie switch, it is judged whether the normally open tie switch is in a closed switch list, if yes, the search is continued, if not, the search of the corresponding topology branch is stopped; if the searched device is a power device other than the bus, the transformer or the normally open tie switch, the search is continued; when a plurality of transformers corresponding to the power distribution network power failure line are obtained based on the search, power grid connectivity analysis is performed on each of the transformers according to the power distribution network power failure line to obtain the power failure topology route corresponding to the power distribution network power failure line.

[0125] The power failure analysis module 205 is configured to generate a power failure analysis report corresponding to the power failure event based on the power failure information and the power protection information.

[0126] The power outage management analysis method based on the power generation vehicle power preservation provided in this embodiment acquires work orders based on the request time of the power outage event, so as to reduce the processing amount of the work orders and improve the analysis efficiency. The planned power outage work orders and the power generation vehicle power preservation work orders are acquired at the same time, so as to improve the accuracy of the power outage analysis by combining the planned power outage and the power preservation. Secondly, in the process of power outage analysis, the planned power outage work orders and the power generation vehicle power preservation work orders are one-to-one corresponding by using the power distribution network outage line of the planned power outage work orders and the power distribution network access node of the power generation vehicle, so as to acquire corresponding power outage information and power preservation information according to the corresponding relationship, thereby reducing the processing amount of the power preservation work orders 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 distribution network outage line, so as to accurately acquire the target planned power outage work order corresponding to the power outage event, accurately acquire the power outage information corresponding to the power outage event from the target planned power outage work order, and then acquire the power preservation information corresponding to the power outage information, thereby improving the accuracy of the power outage analysis. Finally, the power outage analysis report corresponding to the power outage event is generated based on the acquired power outage information and power preservation information, thereby improving the efficiency and accuracy of the power outage management analysis.

[0127] Embodiment two

[0128] In the prior art, when the power distribution network is repaired and preserved by the power generation vehicle during power outage, users often consult the power company for specific power restoration information, power outage duration and the like due to sudden power outage and no receipt of 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 reply to the consultation of users, but the method of using manual to reply to the power outage of the current consultation user not only needs a large amount of human cost, and due to the large amount of information to be processed, the manual cannot locate the user in a short time to know the specific power outage and power restoration information of the user, resulting in poor user consultation experience and increasing the risk of customer complaints.

[0129] To solve the above technical problems, the power outage management analysis method based on the power generation vehicle power preservation is provided to improve the efficiency and accuracy of the power outage analysis and to meet the consultation needs of users. Specifically, the specific implementation process of the power outage management analysis method can refer to Figure 3 , mainly including steps 301 to 306, which are mainly as follows:

[0130] Step 301: Acquire the request time of the reported user power outage event, so as to acquire a plurality of first planned power outage work orders and a plurality of first power generation vehicle power preservation work orders associated with the request time.

[0131] In the embodiment, the step mainly comprises: obtaining the request time of the user power failure event, and obtaining the approval state of each work order from the database in which the work orders are stored; obtaining a plurality of original planned power failure work orders and a plurality of original power generation vehicle power protection work orders with the approval state of passing the examination from the database; inputting the original planned power failure work orders and the original power generation vehicle power protection work orders into a preset text recognition model, respectively, to extract the planned power failure start time and the planned power failure end time in the original planned power failure work orders, and the planned power protection start time and the planned power protection end time in the original power generation vehicle power protection work orders. According to the preset time window, the request time, and the planned power failure start time, the planned power failure end time, the planned power protection start time, and the planned power protection end time, a plurality of first planned power failure work orders and a plurality of first power generation vehicle power protection work orders are selected from the plurality of original planned power failure work orders and the plurality of original power generation vehicle power protection work orders.

[0132] Specifically, when a power failure occurs in a certain area, a user can report the power failure event by logging in to a website or calling, etc. After the power supply system receives the power failure event input by the user or the staff, the input time of the power failure event is first obtained as the request time. Secondly, since the planned power failure of the power distribution network and the power protection by the power generation vehicle during the planned power failure both need to report the planned power failure work order and the power generation vehicle power protection work order in the power supply system in advance to perform the subsequent power failure operation and power protection operation, the power failure information and the power protection information corresponding to the power failure event can be obtained by querying the work order. Further, since a large number of work orders are stored in the database, the work orders include the to-be-executed work orders with the approval passed and the scrapped work orders with the approval failed. If a power failure event occurs, it means that the planned power failure work order corresponding to the area where the power failure event occurs is approved and is being executed. In order to reduce the data amount of the work order query and the accuracy of the subsequent corresponding data acquisition, a plurality of original planned power failure work orders and a plurality of original power generation vehicle power protection work orders can be first selected according to the approval state of each work order.

[0133] Further, after screening based on the approval state, the search range 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 January 2, 2025, 13:56, the planned power outage work order and the power generation vehicle power protection work order close to the request time can be found according to the dynamically set time window. Specifically, a text data model capable of identifying the text content of 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 and end power outage times in the planned power outage work order and the planned start and end power protection times in the original power generation vehicle power protection work order. Then, the time difference between the planned start power outage time, the planned end power outage time, the planned start power protection time and the request time is calculated. Further, the first planned power outage work order and the first power generation vehicle power protection work order are screened out.

[0134] Step 302: Obtain the power distribution network outage line corresponding to the first planned power outage work order and the power distribution network access node of the power generation vehicle in the first power generation vehicle power protection work order, and construct the association relationship between the first power generation vehicle power protection work order and the first planned power outage work order based on the power distribution network outage line and the power distribution network access node.

[0135] In this embodiment, this step mainly includes: inputting the first power generation vehicle power protection work order and the first planned power outage work order into the pre-constructed 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 power generation vehicle in the first power generation vehicle power protection work order; obtaining the power distribution network outage line corresponding to the planned power outage line from the power distribution network GIS system according to the planned power outage line and the power generation position; matching the power distribution network access node and the power distribution network outage line to obtain the association relationship between the first power generation vehicle power protection work order and the first planned power outage work order.

[0136] Specifically, the first power generation vehicle power protection work order and the first planned power outage work order are input into the pre-constructed text recognition model for power outage area identification and power generation vehicle power generation position identification to output the specific power generation position of each power generation vehicle in the power generation vehicle power protection work order and the power outage area in each planned power outage work order; then, the GIS service of the power distribution network is called, the latitude and longitude information of the power outage area and the power distribution network access node is input, the local power grid topology network where the latitude and longitude information is located is obtained, and the power distribution network line corresponding to the local power grid topology network and the power distribution network access node are obtained from the power distribution network production management system.

[0137] Further, after obtaining the distribution network line in the planned power outage work order and the distribution network access node of the power generation vehicle in the power generation vehicle power protection work order, whether the distribution network access node belongs to a node corresponding to a certain standby switch position in the distribution network line is identified by traversing 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 generation vehicle power protection work order currently matched and the planned power outage work order is constructed, so that the corresponding power generation vehicle power protection work order is matched from the planned power outage work order according to the mapping relationship. That is, the power generation vehicle power protection work order corresponds to one planned power outage work order.

[0138] Step 303: Obtain the transformer area number corresponding to the user power outage event, and obtain the power grid topology route where the transformer area number is located from the distribution network GIS system.

[0139] In this embodiment, this step mainly responds to the reported user power outage event, identifies the address information input by the user in real time, and then traverses and matches the keywords in the address information with the keywords in the standard address library, and then obtains the standard address corresponding to the address information and the transformer area number associated with the standard address. According to the power grid topology network, the GIS service of the distribution network is called, the transformer area number is input, the local power grid topology network where the user power outage event is located is obtained, and the corresponding relationship between the transformer area number and the transformer area number in the local power grid topology network is obtained from the distribution network production management system. The transformer area number in the local power grid topology network is obtained, and the corresponding relationship between the transformer area number and the transformer area number in the local power grid topology network is obtained from the distribution network production management system. According to the corresponding relationship, the power grid topology route in the user power outage event is finally obtained.

[0140] Specifically, when power outage occurs in a certain transformer area, the power outage information collection terminal set will collect the power outage event reported by the user in real time, and locate the current user after obtaining the power outage event to identify the power equipment that has power outage. Specifically, in the process of positioning, the address of the power outage event reported by the user needs to be analyzed first to determine the transformer area number where the user is located, so as to reduce the positioning time of the equipment and improve the efficiency of power outage analysis.

[0141] Preferably, in the process of address resolution, due to the possibility of missing or different address expressions in the address information uploaded by the user, the embodiment needs to convert the address uploaded by the user into a standard address for matching the transformer area number. Optionally, in the process of matching the standard address, because the standard address is often structured information, and the address uploaded by the customer is more arbitrary and unstructured, the unstructured information uploaded by the user needs to be translated into structured information. For this purpose, in some modes of the embodiment, an address resolution positioning model is constructed to use administrative division, standard address, customer number, customer name, contact information and other data to comprehensively compile and analyze the customer address and accurately determine the customer location, thereby providing support for fault research, accurate order allocation, geographical distribution and other businesses. Specifically, in the embodiment, according to the order of regional hierarchical division, the geographical information of each level is identified and extracted from the unstructured work order information through top-down layer-by-layer retrieval and comparison, and the structured address information meeting the standard requirements is constructed through supplementation and improvement, for example, the address uploaded by the user is Guangzhou Baiyun, and the model is supplemented and improved to form Guangzhou Baiyun District, Guangdong Province.

[0142] Further, after analyzing the address information uploaded by the user, the keywords in the address information are matched with the standard address library through keyword traversal, and the matching method includes but is not limited to pictographic matching and pinyin matching. After the matching is completed, the standard address information can be matched with the transformer area standard address library data, and the accurate matching transformer area list obtained is analyzed to determine the transformer area number. In the embodiment, the matched structured standard address is matched with the transformer area standard address library data in the marketing business application system, and the transformer area region containing the user address and the transformer area number corresponding to the transformer area region are obtained.

[0143] Step 304: Based on the power grid topology route and the power distribution network outage line, the target planned power outage work order corresponding to the user power outage event is obtained from a plurality of first planned power outage work orders, and the target planned power outage work order corresponding to the target power generation car power protection work order is obtained according to the association relationship.

[0144] In the embodiment, the step mainly comprises: taking the power distribution network outage line as a starting point, searching each topology branch connected with the power distribution network outage line; for each topology branch of the power distribution network outage line, if the searched device is a bus, judging 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 of the corresponding topology branch, and taking the previous device of the bus as a power supply, if the same, continuing the search; if the searched device is a distribution transformer, stopping the search of the corresponding topology branch; if the searched device is a normally open tie switch, judging whether the normally open tie switch is in the closed switch list, if yes, continuing the search, if not, stopping the search of the corresponding topology branch; if the searched device is a power device other than the bus, transformer or normally open tie switch, continuing the search. When all the transformers corresponding to the power distribution network outage line are obtained through the search, the power grid connectivity of each transformer is analyzed according to the power distribution network outage line, to obtain the power distribution network outage line involved in the planned outage work order, and the route coincidence degree of the power distribution network outage line and the power grid topology route is calculated, to obtain the planned outage work order corresponding to the user outage event from the plurality of first planned outage work orders and the power generation vehicle power protection work order corresponding to the planned outage work order according to the association relationship.

[0145] Specifically, according to the user input data, a starting query condition is constructed to prepare for topology tracking, necessary conditions are power distribution network outage lines, optional conditions are a list of switches to be opened and a list of switches to be closed in the power grid; various input devices are power grid devices selected and specified from a map in a graphical interface system by a mouse, and a source device type and a device ID obtained by searching can find a starting device for analysis in a database, and a list of switches to be opened and a list of switches to be closed can also be queried. In the tracking process, a single-source breadth tracking is performed from each device in the power distribution network outage lines to be powered off in the device topology network; all power sources supplying power to each device in the power distribution network outage lines to be powered off are collected as search sources for subsequent steps, and all distribution transformers encountered are collected; in the tracking process, each searched device is judged to determine whether to record the device, continue to search other devices connected to the device, or stop the subsequent search of 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, the bus is a medium voltage side bus of the substation, which is the power source of the current branch, at this time, the search of the branch is not continued, and the previous device of the bus is recorded as a power source and added to a power source 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 substation; note that the previous device of the bus on the power supply link is taken as the power source, because other outgoing lines of the bus may lead to tracking of other power distribution networks, affecting the result; if the searched device is a transformer, the distribution transformer is recorded and added to a transformer list, and the search branch is not continued; if the searched device is a switch and is a normally open tie switch: if the switch is in the closed switch list, the tracking path is considered as non-blocking and continues to advance without direction; otherwise, as a normally open switch, the search branch is not continued; if the searched device does not meet the above conditions or is other power equipment, the search is continued. In the tracking process, the corresponding attributes of the device are read according to the device type, the corresponding operation is performed on the device that meets the conditions, and it is determined whether the topology branch needs to continue; if the branch continues to be tracked, other devices connected to the device are added to a to-be-tracked list, and a device is taken from the to-be-tracked list for judgment; the tracking is repeatedly continued until there is no device in the to-be-tracked device list. In this step, all devices connected together through switches from each device in the power distribution network outage lines to be powered off are encountered, all power sources supplying power to each device in the power distribution network outage lines to be powered off are collected as search sources for subsequent steps, and all distribution transformers encountered are collected.Further, in acquiring the power equipment information involved in the power failure event, the associated power equipment is iteratively found from the known power failure transformer step by step downward according to the topological relationship information of the power grid until the power terminal equipment in the power grid is found. Through analysis and statistics of the power failure data information, the power equipment involved in the power failure event can be obtained, such as transformer a, transformer b, and transformer c. Starting from these known power equipment, connectivity analysis is performed according to the topological relationship of the power grid, and the associated power equipment is iteratively found step by step downward until the power terminal equipment in the power grid is found.

[0146] Step 305: Acquire the power failure information and power protection information in the target planned power failure work order and the target power generation vehicle power protection work order.

[0147] In this embodiment, this step mainly includes: performing data conversion and error correction on the acquired target planned power failure work order and the target power generation vehicle power protection work order, respectively, to remove the error information in the work order and improve the accuracy of information extraction; then, labeling the power failure information description text and the power protection information description text in the work order sample, training the word vector through the 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, and locating the starting position of the power failure information and the power protection information in the work order through the trained deep learning model, and then extracting the corresponding power failure information and power protection information from the target planned power failure work order and the target power generation vehicle power protection work order according to the starting position.

[0148] Specifically, in this embodiment, the sample is labeled, the historical work order is acquired, the power failure information description text and the power protection information description text in the work order sample are labeled, and the labeled sample is obtained, where B represents the beginning of the text, I represents the middle of the text, E represents the end of the text, and O represents non-power failure information text and non-power protection information text. The word vector is trained through the word embedding WordEmbedding technology 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 by using the CBOW model in the word2Vec algorithm. There are multiple ways of text vectorization, and compared with the Tf-idf and the bag-of-words method, the WordEmbedding of this embodiment can effectively capture the context relationship of words, fully utilize massive data, and achieve better model effect. The advantage of this embodiment is that the word vector matrix trained by using the traditional WordEmbedding is obtained by training general domain text, and the effect is poor when applied to the text model in the power field; and the word vector matrix of this embodiment is obtained by training the text in the power field, and better precision and generalization ability will be achieved when applied.

[0149] Then, the named entity recognition model is trained by using the labeled samples and the word vector matrix by using the BiLSTM+CRF algorithm, and the power failure information and the power protection information are identified by using the trained named entity recognition model. The named entity recognition model comprises a data input layer, after the input text is segmented, it becomes sequence data, and the word vector matrix trained according to the data input layer is converted into a corresponding vector, which is input into the next layer to extract features by the BiLSTM model; a feature extraction layer, a BiLSTM model is constructed to automatically extract the feature representation of the observation sequence, which is input into the next layer for CRF model training; a model training layer, the features transmitted from the feature extraction layer are input, the label judgment of each text node is output, and the CRF model is trained by adjusting the parameters until convergence.

[0150] Step 306: matching the power failure information corresponding to the short message template, to generate a power failure analysis short message for replying to the user power failure event based on the power failure information, the power protection information and the short message template.

[0151] In this embodiment, the step mainly comprises: determining the power failure type according to the power failure information; matching the short message template corresponding to the power failure type; obtaining the configuration information of the short message template, and adding the power failure information and the power protection information to the short message template according to the configuration information to form a reply short message; and sending the reply short message to the user power failure event.

[0152] The power failure reason category corresponding to the power failure information in the planned power failure work order is obtained by using the constructed work order classification model; wherein the category includes guaranteeing all power and guaranteeing part of power. Different power failure reason categories correspond to different short message templates; for example, the short message template corresponding to the guarantee part of power exists pre-setting, fixed "power protection period, please do not use high-power electrical appliances", while the short message category corresponding to the guarantee all power does not exist. Then, after calling the corresponding short message template, the short message template is configured and parsed to determine the display area and display size of the power failure information and the power protection information in the short message template, and then the power failure information and the power protection information are added to the short message template according to the display area and the display size to generate a power failure information analysis short message. Then, when replying to the power failure information analysis short message, the contact information of all users affected by the power failure can be obtained, and the power failure information analysis short message can be sent according to the contact information, or the contact information of the user reporting the power failure time can be obtained to send the power failure information analysis short message according to the contact information.

[0153] The application discloses a power outage management analysis method for power generation vehicle power protection. First, the power outage time in the reported user power outage event is obtained from the database storing the approved work order, and a plurality of first planned power outage work orders and a plurality of first power generation vehicle power protection work orders associated with the power outage time are obtained, so as to reduce the amount of work order data required for corresponding work order matching and improve the efficiency of power outage information and power protection information acquisition. Further, in order to accurately locate the power outage work order corresponding to the power outage event and the power generation vehicle work order for power protection of the power outage event, the power generation vehicle power protection work order and the first planned power outage work order are analyzed first, so as to complete the association of power outage and power protection according to the power distribution network outage line and the power distribution network access node corresponding to the power generation vehicle power protection work order and the planned power outage work order, and then the association is used to realize the accurate correspondence between power protection and power outage. Then, in order to accurately obtain the power outage information and power protection information corresponding to the power outage event, the power grid topology route of the power outage event and the power distribution network outage line are matched. After obtaining the corresponding planned power outage work order and the power generation vehicle power protection work order, the corresponding power outage information and power protection information are obtained from the planned power outage work order and the power generation vehicle power protection work order, and the corresponding short message template is called according to the power outage information, so as to generate accurate reply short messages and meet the power outage consultation demand of users.
