Description

Technical Field

[0001] The present invention relates to the field of power grid technology, and in particular to a method, device and storage medium for locating power faults assisted by customer service work orders. Background Art

[0002] With economic development and population growth, the scale of power systems continues to expand and become increasingly complex. The power grid covers a wider area, involving more substations, transmission lines, distribution lines and various types of power equipment. The topology of the power system has become more complex, including the widespread use of underground cable networks, which greatly increases the possibility and complexity of faults. Traditional fault location methods have gradually shown their limitations in this complex environment and are difficult to meet the requirements of fast and accurate power restoration.

[0003] Manual inspection is one of the traditional means of fault location. Workers conduct on-site inspections along the power lines. Manual inspections are inefficient, especially in large-scale power outages or complex geographical environments. For example, manual inspections of power lines in mountainous or forested areas require a lot of time and manpower, and may be limited by natural factors such as weather and terrain. At the same time, manual inspections have poor real-time performance and are usually carried out in a certain cycle. Faults cannot be discovered in a timely manner, and the fault location cannot be quickly determined after the fault occurs, resulting in extended power outages. In addition, the effectiveness of manual inspections depends largely on the experience and expertise of the staff. Different staff may have different abilities to judge and locate faults. Inexperienced personnel may miss some important fault signs, resulting in inaccurate fault location or delayed fault repair time.

[0042] In this embodiment, a method for locating power faults based on customer service work orders and assisted by customer service work orders running on electronic equipment is provided. Figure 1 FIG. 1 is a flow chart of a method for locating a power fault based on a customer service work order according to one embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0043] Step S10, receiving a plurality of customer service work orders from a marketing management system, wherein the marketing management system is used to associate and store customer information with service records, and the plurality of customer service work orders are used to record feedback from different customers regarding the current power outage event to assist in locating the power fault;

[0044] In the embodiment of the present invention, the marketing management system can be understood as a comprehensive platform used by the power company to manage matters related to customer relations, and is mainly responsible for customer information management, service request processing, bill management, and customer service. For example, in the power system, the marketing management system not only stores the basic information of the customer (such as name, address, contact information, etc.), but also saves the customer's service records, including service requests, fault reports, electricity bills, etc. The marketing management system can provide the power company with a comprehensive customer service history and real-time status by associating and storing customer information and service records, which is not limited here.

[0045] A customer service ticket can be understood as a file in the marketing management system used to record customer issues and requests. For example, when a customer reports a power failure, service interruption, or any abnormal situation related to power supply to the power company, the customer service staff will create a customer service ticket. The ticket contains the customer's detailed contact information, fault description, reporting time and location, etc. The customer service ticket is the starting point of the process of handling customer issues within the power company, and is used to guide subsequent technical support, troubleshooting, and repair work, which is not limited here.

[0046] The feedback content of power outage events can be understood as the specific description and information provided by customers to the power company when they experience power failure or power outage. The feedback content of power outage events can include the time and location of the failure, the specific manifestations of the failure (such as sudden power outage, flickering, burning smell, abnormal noise, etc.), and any information observed by the customer that may be related to the failure (such as nearby construction activities, abnormal weather, etc.).

[0047] Receiving multiple customer service work orders from the marketing management system can be understood as the power company or related maintenance department automatically or manually retrieving and obtaining a series of customer service request records related to the current power failure or power outage event from its internal customer relationship management or marketing management system.

[0048] In an embodiment of the present invention, customer feedback information related to the current power outage event is collected through the marketing management system. By analyzing the customer feedback information, the possible manifestations and impact range of the power failure can be obtained. Combined with the geographic location information, valuable first-line data is provided for subsequent fault location analysis, thereby helping the power company to quickly and accurately locate the fault point and restore power supply.

[0049] Step S11, filtering out a target customer service work order from multiple customer service work orders by performing a keyword query on the customer service work order;

[0050] In the embodiment of the present invention, keyword query can be understood to refer to the process of automatically or manually searching for predefined keywords or phrases in the text content of the received customer service work order. Exemplarily, the keywords can be specific words related to power failures, such as "power outage", "flash", "smoke", "explosion", etc. These words can indicate that the event described in the work order may be related to the current power failure. The purpose of keyword query is to quickly filter out work orders directly related to power failures from a large number of customer service work orders, narrow the scope of analysis, and improve the efficiency of locating faults, which is not limited here.

[0051] The target customer service work order can be understood as a set of work orders that are determined to be associated with the current power failure after keyword query. For example, the target customer service work order contains detailed information reported by the customer after the power failure occurs, such as a specific description of the failure, the location and time of the failure, etc., which is not limited here.

[0052] By performing keyword queries on customer service tickets, selecting target customer service tickets from multiple customer service tickets can be understood as a result based on keyword queries. The system will automatically select those tickets containing at least one keyword related to power failure from a large number of customer service tickets, namely, target customer service tickets.

[0053] In an embodiment of the present invention, keyword queries are performed on customer service work orders to select target customer service work orders from multiple customer service work orders, which is an information screening and refining step in power fault locating. The system uses keywords as screening criteria to automatically identify information directly related to the fault from a large amount of text data fed back by customers, providing strong data support for accurate positioning and timely response to power faults.

[0054] Step S12, converting the address information in the target customer service work order to obtain a conversion result;

[0055] In the embodiment of the present invention, the conversion result can be understood as referring to the conversion of the customer address described in the target customer service ticket from text form to a coordinate form that can be used for geospatial analysis, usually longitude and latitude coordinates.

[0056] The address information in the target customer service ticket is converted, and the conversion result can be understood as converting the customer's geographical location described in the customer service ticket from an unstructured text form into precise geographical coordinate data, usually longitude and latitude coordinates. For example, if the address information in a customer service ticket is "Building 5, a community in Pengjiang District, Jiangmen City, Guangdong Province", it is converted into longitude and latitude coordinates (such as 22.60, 113.10) through geocoding, and the power company can quickly find the location in its GIS system and compare it with the power lines related to the power outage event, thereby accelerating the confirmation of the fault area, which is not limited here.

[0057] In an embodiment of the present invention, by converting customer address information into geographic coordinates, maintenance personnel can directly locate the specific location of the customer on a single-line diagram or a GIS map of the power system, and then analyze the geographical relationship between the location and the power lines and equipment, and combine the fault phenomenon described in the work order to more accurately locate the fault point, guide on-site maintenance work, and improve the safety and efficiency of power system operations.

[0058] Step S13, determining the target line number corresponding to the conversion result;

[0059] In the embodiment of the present invention, the target line number can be understood as referring to the geographic coordinate data obtained by converting the customer's fault reporting address information, and further matching it to the unique identification code of the power line in the power system that is specifically responsible for supplying power to the geographic coordinate location.

[0060] Determining the target line number corresponding to the conversion result can be understood as comparing and analyzing the longitude and latitude coordinates of the customer's fault reporting address obtained through geocoding conversion with the line geographic information in the power system in the process of power fault location, so as to determine the unique identification code of the specific power line responsible for supplying power to the customer's address area.

[0061] In the embodiment of the present invention, the determination of the target line number enables power maintenance personnel to quickly locate the specific line where the fault may occur, and conduct more in-depth fault analysis and location based on the operating data of the line, historical fault records and fault descriptions in customer work orders, thereby speeding up fault handling and improving the reliability of power supply services.

[0062] Step S14, marking the target customer service work order on the single line diagram according to the target line number to obtain a marking result;

[0063] In the embodiment of the present invention, the single-line diagram can be understood as a simplified version of the power system circuit diagram, which usually uses a single line to represent the power line, omitting the multi-phase details of the line, and is used to intuitively display the topological structure and equipment connection relationship of the power system, so as to facilitate power system planning, operation and maintenance personnel to quickly understand the direction and connection status of the power line.

[0064] The marking result can be understood as the result of marking the customer fault reporting location related to the power failure with a specific symbol or color on the single-line diagram according to the target line number and the keyword information in the customer fault reporting work order. Exemplarily, the system will find the line corresponding to the target line number on the single-line diagram, and then mark a mark on the single-line diagram near the line according to the geographic coordinates of the customer fault reporting address, such as a red dot or a flashing icon, to indicate the location where the customer reported the fault. The mark can also include detailed information of the fault reporting work order, such as the reporting time, fault description keywords, etc., which are not limited here.

[0065] Marking the target customer service work order on the single-line diagram according to the target line number, and obtaining the marking result can be understood as in the planning and maintenance of the power system, when a customer fault report work order is determined to be associated with a certain line, the maintenance personnel or the automation system will find the representation of this line on the single-line diagram of the power system, and then according to the longitude and latitude coordinates of the customer address in the work order, the corresponding position point or area on the corresponding line on the single-line diagram is marked significantly to intuitively show the relationship between the fault reporting location and the power line. For example, suppose that a fault described in a customer service work order occurs at a specific location in Pengjiang District, Jiangmen City. After the location is converted into longitude and latitude coordinates through geocoding, the target line number is determined to be "L123". Next, the maintenance personnel or the automation system will find the "L123" line on the single-line diagram and make a mark on the nearest node or line segment corresponding to the customer fault reporting location on the line diagram, such as using a red dot or an icon with a pop-up information box. The marking result not only shows the geographical location of the fault, but also may show the keywords "spark" and "smoke" in the work order, as well as the specific time of the fault reporting, etc., which are not limited here.

[0066] In an embodiment of the present invention, the system automatically or manually marks the location point or line segment closest to the customer's fault reporting location with a specific symbol or color on the single-line diagram corresponding to the target line, thereby obtaining a marking result. The marking result not only visually highlights the possible location of the fault, but may also contain key information of the customer's work order, such as the description of the fault phenomenon, the reporting time, and the customer's contact information, providing a clear and detailed fault location reference for power maintenance personnel, speeding up the speed and efficiency of fault handling, and significantly improving the responsiveness of the power system and the quality of customer service.

[0067] Step S15, when using the single-line diagram to perform fault analysis, assist in locating the power fault corresponding to the current power outage event based on the marking result and the content description of the target customer service work order.

[0068] In the embodiment of the present invention, the power failure corresponding to the power outage event can be understood as a fault point or fault type directly associated with the currently reported power outage. For example, if multiple customers report a fault in the same area, and the description keywords are "smoke" and "sparks", then by marking these work order locations on the single-line diagram, combined with the status records of the power equipment in the area before and after the fault occurs, the power maintenance personnel can infer that the fault may be caused by a line short circuit or equipment overheating, which is not limited here.

[0069] Assisting in locating the power fault corresponding to the current power outage event based on the marking results and the content description of the target customer service work order can be understood as using the customer's fault reporting location information marked on the power system single-line diagram, combined with the customer's specific description of the fault in the work order, to help power maintenance personnel or automation systems more accurately determine the fault location and cause of the power outage event.

[0070] In an embodiment of the present invention, based on these marking results and work order content information, power maintenance personnel can quickly identify the key area where the fault occurs on the single-line diagram, and combine the operating data and historical records of the power system to perform fault analysis, locate the fault point, and formulate a repair plan, thereby improving the accuracy and efficiency of fault location, reducing the scope and time of on-site inspections by power maintenance personnel, and helping to restore power supply faster.

[0071] In the embodiment of the present invention, customer feedback information related to the current power outage event is collected through the marketing management system. By analyzing the customer feedback information, the possible manifestations and impact range of the power failure can be obtained, and combined with the geographic location information, valuable front-line data is provided for subsequent fault location analysis, thereby helping the power company to quickly and accurately locate the fault point and restore power supply. By performing keyword queries on customer service work orders, the target customer service work order is selected from multiple customer service work orders, which is an information screening and refining step in power fault location. The system uses keywords as screening criteria to automatically identify information directly related to the fault from a large amount of text data fed back by customers, providing strong data support for the accurate positioning and timely response of power failures. By converting customer address information into geographic coordinates, maintenance personnel can directly locate the specific location of the customer on the single-line diagram or the GIS map of the power system, and then analyze the geographical relationship between the location and the power line and equipment, and combine the fault phenomenon described in the work order to more accurately locate the fault point, guide on-site maintenance work, and improve the safety and efficiency of power system operation. The determination of the target line number enables power maintenance personnel to quickly locate the specific line where the fault may occur, and conduct more in-depth fault analysis and location based on the operation data, historical fault records and fault descriptions in the customer work order of the line, thereby speeding up the fault handling speed and improving the reliability of power supply services. The system automatically or manually marks the location point or line segment closest to the customer's fault reporting location with a specific symbol or color on the single-line diagram corresponding to the target line, thereby obtaining the marking result. The marking result not only visually highlights the possible location of the fault, but also may contain key information of the customer work order, such as fault phenomenon description, fault reporting time and customer contact information, providing a clear and detailed fault location reference for power maintenance personnel, speeding up the speed and efficiency of fault handling, and significantly improving the responsiveness and customer service quality of the power system. Based on these marking results and work order content information, power maintenance personnel can quickly identify the key areas where the fault occurs on the single-line diagram, and conduct fault analysis, locate the fault point and formulate a repair plan based on the operation data and historical records of the power system, thereby improving the accuracy and efficiency of fault location, reducing the scope and time of on-site investigation of power maintenance personnel, and helping to restore power supply faster.

[0072] Through the above steps, by receiving multiple customer service work orders from the marketing management system, wherein the marketing management system is used to associate and store customer information and service records, and the multiple customer service work orders are used to record the feedback content of different customers regarding the current power outage event to assist in locating the power fault; by performing a keyword query on the customer service work order, a target customer service work order is screened out from multiple customer service work orders; the address information in the target customer service work order is converted to obtain a conversion result; the target line number corresponding to the conversion result is determined; the target customer service work order is marked on the single-line diagram according to the target line number to obtain a marking result; when using the single-line diagram for fault analysis, the power fault corresponding to the current power outage event is assisted in locating based on the marking result and the content description of the target customer service work order, thereby achieving the purpose of using the marking information and the work order content for effective fault analysis, thereby achieving the technical effect of accurate fault location, timely response, high cost-effectiveness and strong adaptability, thereby solving the technical problems in the related technology that the fault location basically relies on manual inspection, resulting in low efficiency, poor real-time performance and high requirements for personnel experience.

[0073] Optionally, the method for locating a power fault based on a customer service work order further includes:

[0074] Based on the associated phenomena and associated features of power failures, a keyword library is created, wherein the keyword library is used to store various types of keywords that assist in locating power failures, and the keyword library is regularly updated according to the continuous evolution of power failure types and manifestations.

[0075] In the embodiments of the present invention, the associated phenomenon can be understood as observable changes perceived by the external environment or users when a power failure occurs. Exemplarily, the associated phenomenon may include fire or smoke: usually a direct manifestation of a line short circuit or equipment overheating, abnormal sounds: such as discharge sounds and explosion sounds, which may be caused by abnormal operation or failure of electrical equipment, physical damage: such as collapsed poles and broken lines, which are often caused by external factors such as bad weather and external force damage, and abnormal odors: such as specific odors that may be produced when equipment overheats or certain materials burn, which are not limited here.

[0076] The associated features can be understood to refer to data changes within the power system, such as voltage drop, current fluctuation, frequency anomaly, etc., which are not limited here.

[0077] The keyword library can be understood as a database pre-established and maintained in the power fault location system, which is used to store a collection of words that describe power fault-related phenomena and characteristics. Exemplarily, the keyword library is summarized based on the types of power faults, common manifestations, and power system operation experience, and is intended to quickly identify information directly related to power faults in fault work orders through automatic or manual search. Exemplarily, the keyword library may contain specific words such as arc, short circuit, overload, lightning strike, equipment smoking, voltage sag, and keywords for external factors such as car accidents and animals that may indirectly cause power failures, which are not limited here.

[0078] Based on the associated phenomena and associated characteristics of power failures, creating a keyword library can be understood as summarizing the various external manifestations and internal indicators when power failures occur, extracting a series of keywords closely related to fault location, and organizing and storing these keywords in a special database or list.

[0079] In the embodiment of the present invention, a keyword library is created based on the associated phenomena and associated features of power failures, so as to quickly identify and extract valuable information when analyzing customer fault reporting work orders, thereby assisting in the accurate positioning of power failures.

[0080] Optionally, in step S11, filtering out a target customer service work order from multiple customer service work orders by performing a keyword query on the customer service work order may include the following execution steps:

[0081] Step S111, performing a keyword query on the customer service ticket according to a preset keyword extraction method to obtain a query result, wherein the query result is used to determine whether the customer service ticket contains a keyword stored in the keyword library;

[0082] Step S112: Filter out a target customer service work order from multiple customer service work orders based on the query result.

[0083] In the embodiment of the present invention, the preset keyword extraction method can be understood as referring to using a predefined rule or algorithm to identify keywords related to power fault location in the work order text when processing a customer service work order.

[0084] The query result can be understood as a set of information that matches the keywords stored in the keyword library and is found by the system according to a preset keyword extraction method after a keyword query is performed on the customer service ticket. Exemplarily, the query result includes all keywords found in the customer service ticket, as well as contextual information related to these keywords, and may also include detailed data such as the location and number of occurrences of the keywords in the ticket text, which are not limited here.

[0085] According to the preset keyword extraction method, keyword queries are performed on customer service work orders. The query results can be understood as the system applying a specific text analysis algorithm to perform deep text mining on the fault reporting work orders received by the customer service center to find and mark words or phrases that match the pre-established keyword library, thereby identifying specific information described in the work order that may be associated with power failures, i.e., the query results.

[0086] Filtering out target customer service work orders from multiple customer service work orders based on the query results can be understood as using the keyword query results previously extracted from the customer service work orders to further filter out those specific work order sets that are most likely to be directly related to the power failure currently being investigated, namely, the target customer service work orders.

[0087] In the embodiment of the present invention, the power fault location system first automatically identifies the fault-related information from the unstructured text of the customer service work order through keyword query. Based on the query results, a series of rules and algorithms are used to screen out the target customer service work orders, that is, those work orders containing key clues, to provide accurate customer feedback basis for power system fault analysis and location. Through the above steps, the speed and accuracy of the response to power faults are greatly improved, and the burden of manual work order processing is also reduced.

[0088] Optionally, in step S12, converting the address information in the target customer service ticket to obtain the conversion result may include the following execution steps:

[0089] Step S121, extracting address information from the target customer service ticket, wherein the address information is described in a natural language in a text format;

[0090] Step S122, based on the geographic coordinate system, convert the address information into longitude and latitude information to obtain a conversion result.

[0091] In the embodiment of the present invention, the address information can be understood as the specific location information extracted from the target customer service ticket, which describes the location where the customer reported the problem. The address information is usually provided in a natural language in text format, for example, "No. 123 Xingfu Road, Pengjiang District, Jiangmen City, Guangdong Province" or "Near the Power Supply Building, No. 152 Jianshe 2nd Road", which is not limited here.

[0092] The geographic coordinate system can be understood as a coordinate system used to locate any location on the earth's surface. In the scenario of power fault location, the geographic coordinate system is used to convert address information into mathematical coordinates that can be used for spatial analysis and distance calculation.

[0093] The longitude and latitude information can be understood as the specific representation of the address information in the geographic coordinate system, usually expressed in degrees, minutes and seconds or degrees after the decimal point. For example, for the address information of "No. 123 Xingfu Road, Pengjiang District, Jiangmen City, Guangdong Province", its longitude and latitude information may be "22.5984 North Latitude, 113.1073 East Longitude", which is not limited here.

[0094] Extracting address information from the target customer service ticket, wherein the address information is described in a natural language in a text format, can be understood as extracting a specific location description of the fault location reported by the customer in a natural language form from the customer service tickets that are filtered out by keywords and are considered to be related to the current fault.

[0095] Based on the geographic coordinate system, the address information is converted into longitude and latitude information. The conversion result can be understood as using geocoding technology to convert the address information described in natural language in the customer work order into longitude and latitude coordinates clearly identified in the global geographic coordinate system.

[0096] In the embodiment of the present invention, the power fault location system first identifies and extracts the natural language description of the fault reporting address from the customer service work order, and then converts the address information into longitude and latitude coordinates through geocoding, thereby realizing the conversion from unstructured fault reporting information to structured geographic data, which not only improves the accuracy and speed of fault location, but also provides intuitive geographic information support for power workers, which helps to quickly respond to and handle power faults.

[0097] Optionally, in step S13, determining the target line number corresponding to the conversion result may include the following execution steps:

[0098] Step S131, obtaining geographic information data of the current power outage event, wherein the geographic information data includes: starting point coordinates of each line segment in the feeder where the current power outage event is located, end point coordinates of each line segment, and line number of each line segment;

[0099] Step S132, determining the target line number corresponding to the conversion result based on the geographic information data.

[0100] In the embodiment of the present invention, geographic information data can be understood as spatial location information related to the distribution of the power network. Specifically, the geographic information data includes detailed geographic coordinate information of each line segment in the power feeder (i.e., the line that transmits electric energy from the substation to the user), including the starting point coordinates, the end point coordinates, and the line number corresponding to each line segment.

[0101] Feeders can be understood as power lines that output electric energy from substations or distribution stations to supply power to specific areas or user groups. For example, feeders can be overhead lines or underground cables. Their main function is to distribute electricity from high-voltage substations to medium- and low-voltage distribution networks, and then further to end users such as homes and businesses. This is not limited here.

[0102] Acquiring geographic information data of the current power outage event can be understood as collecting spatial location information of power lines and facilities directly related to the current power outage event from the power company's GIS database or related monitoring system.

[0103] Determining the target line number corresponding to the conversion result based on geographic information data can be understood as when the system obtains the latitude and longitude information of the customer's fault reporting location, the system will calculate the spatial distance between the customer's fault reporting location and all line segments in the power system through GIS. Then, according to the preset judgment criteria (such as the distance threshold), determine the line segment closest to the customer's fault reporting location, and further obtain the line number to which the line segment belongs, that is, the target line number, which is not limited here.

[0104] In the embodiment of the present invention, the system first extracts geographic information data directly related to the current power outage event from the GIS database or other monitoring system of the power company. Using the relevant geographic information data, the longitude and latitude conversion results of the customer's fault reporting location are spatially matched and analyzed. By calculating the spatial distance between the customer's location coordinates in the conversion result and the starting and ending coordinates of each line segment in the feeder, the system can determine the line segment closest to the customer's fault reporting location, thereby further locking the line number to which the line segment belongs as the target line number.

[0105] Optionally, in step S132, determining the target route number corresponding to the conversion result based on the geographic information data may include the following execution steps:

[0106] Step S1321, calculating the distance between the conversion result and each line segment in the feeder where the current power outage event is located based on the geographic information data to obtain a calculation result;

[0107] Step S1322, determining the target line number closest to the conversion result according to the calculation result.

[0108] In the embodiment of the present invention, the calculation result can be understood as a series of numerical values ​​including the distance between the customer's fault reporting location and each line segment in the feeder. For example, the calculation of the distance value may be based on a variety of spatial distance algorithms, such as Euclidean distance, Manhattan distance or more complex GIS spatial analysis algorithms, which are not limited here.

[0109] The conversion result is calculated based on geographic information data, and the distance between each line segment in the feeder where the current power outage event is located is obtained. The calculation result can be understood as the numerical result generated after the system calculates the spatial distance between the longitude and latitude coordinates of the customer's fault reporting location and the starting and ending coordinates of all line segments in the feeder where the current power outage event is located based on the acquired geographic information data, that is, the calculation result.

[0110] Determining the target line number closest to the conversion result based on the calculation results can be understood as the system further analyzing these calculation results, and determining the line segment closest to the customer's fault reporting location based on a preset distance threshold or sorting mechanism. The line number where the line segment is located is identified as the target line number.

[0111] In the embodiment of the present invention, the system calculates the spatial distance between the longitude and latitude of the customer's fault reporting location and these segments based on the previously acquired geographic information data of the current power outage event (including the starting point coordinates and the end point coordinates of each line segment in the feeder), and obtains a series of calculation results. From the above calculation results, the line segment closest to the customer's fault reporting location is analyzed and determined, and then the line number to which the line segment belongs is locked as the target line number. By screening the minimum distance value, an accurate match from the customer's fault reporting information to the specific location of the power feeder is achieved, providing power maintenance personnel with an accurate direction for troubleshooting, which helps to quickly locate and repair power faults.

[0112] Optionally, in step S15, assisting in locating the power fault corresponding to the current power outage event based on the marking result and the content description of the target customer service work order may include the following execution steps:

[0113] Step S151, determining the position of the line segment suspected of having a fault based on the marking result, and determining the keyword indication content based on the content description of the target customer service work order;

[0114] Step S152: using the line segment position and the keyword indication content to assist the target object in locating the power fault corresponding to the current power outage event.

[0115] In an embodiment of the present invention, the location of the line segment suspected to have a fault can be understood as the power feeder line segment closest to the fault location described by the customer in the fault reporting work order, determined by the system analyzing the geographical location information of the customer's fault reporting work order and combining it with the geographical layout data of the power feeder.

[0116] The keyword indication content can be understood as specific words or phrases that may describe the fault phenomenon or situation in the customer's fault report. The above words or phrases are called keywords. For example, keywords may include smoke, sparks, fractures, etc. The above keywords can provide the nature of the fault, possible causes or specific manifestations of the fault, which are not limited here.

[0117] The target object can be understood as maintenance personnel, which is not limited here.

[0118] Determining the line segment location suspected of having a fault based on the marking results, and determining the keyword indication content based on the content description of the target customer service ticket can be understood as the system has marked the customer fault reporting ticket on the power single line diagram. The system will calculate the spatial distance between these fault reporting locations and each line segment in the power feeder based on the marked customer fault reporting location through GIS and other technologies. Based on the calculation results, the system can identify the line segment closest to the customer fault reporting location and determine these line segment locations as the line segment locations suspected of having a fault. At the same time, the system identifies keywords from the text content of the customer service ticket to describe the characteristics and possible causes of the fault.

[0119] Using the line segment position and keyword indication content to assist the target object in locating the power fault corresponding to the current power outage event can be understood as the system comprehensively analyzing the line segment position information of the suspected faulty power feeder and the keyword indication content extracted from the target customer service ticket. The system can provide a preliminary fault location report, clearly indicating the line segment position of the suspected fault and the nature of the fault reflected by the keyword indication content. For example, the fault location report may indicate that the fault occurred in a specific section of a line and was associated with spark phenomena reported by multiple customers, instructing maintenance personnel to prioritize checking the electrical connection of the line segment, which is not limited here.

[0120] In an embodiment of the present invention, the system first determines the location of the power line segment most likely to be related to the fault reporting location based on the previous marking result, that is, the geographic location mark of the customer's fault reporting work order on the power network single-line diagram. The system combines the line segment location information with the keyword indication content to provide power maintenance personnel with auxiliary information for locating the fault. Based on this information, the maintenance personnel can focus on the suspected fault line segment in a direction during on-site inspections, and at the same time judge the possible fault type based on the keyword indication content, thereby more effectively locating and handling power faults and reducing the time for power restoration.

[0121] Figure 2 is a flow chart based on work order marking and fault analysis according to one embodiment of the present invention, such as Figure 2As shown, the method based on work order marking and fault analysis in the embodiment of the present invention mainly includes obtaining the customer service work order associated with the current power outage event, automatically querying whether there are preset keywords in the work order, screening out the fault reporting work order containing the keywords, extracting the address information of the fault reporting user and converting it into longitude and latitude, calculating the distance between the customer's longitude and latitude and each line segment of the feeder where the power outage event is located, finding the line number near the fault reporting work order, marking the customer's fault reporting work order on the single line diagram, and the staff referring to the marked work order to assist in locating the fault point. Before executing the above steps, the present invention also includes the creation and management of keywords. Specifically, based on the various phenomena and characteristics that may be presented by power failures, keywords for assisting fault location are created in advance. Figure 3 Schematic diagram of keyword creation and management according to one embodiment of the present invention. Figure 3 As shown in the figure, the keywords cover a variety of types such as "fire", "light", "smoke", "car accident", and "sound". "Fire" and "light" are selected because power failure may cause short circuits or overloads, thereby generating open flames or abnormal bright light; "smoke" may be a manifestation of overheating and smoking of lines or equipment; "car accidents" may cause damage to power facilities such as telephone poles; "sound" includes abnormal sounds such as discharge sounds and explosions, which may be related to the failure. The keyword library is not static. With the further understanding of the types and manifestations of power failures and the emergence of new failure situations, the keyword library needs to be updated and optimized regularly. For example, if it is found that a new type of equipment failure is often accompanied by a specific smell, the relevant smell description can be added to the keyword library.

[0122] Work order acquisition and keyword query mainly include the source of work order acquisition and the automated query process. Figure 4 is a schematic diagram of work order acquisition and keyword query according to one embodiment of the present invention, such as Figure 4 As shown in the figure, customer service tickets related to the current power outage are obtained from the marketing management system. The marketing management system is the core system for power companies to store customer information and service records. The tickets in the marketing management system contain detailed customer feedback on power outages and are an important source of information for fault location. Through a specially designed automation program, keyword searches are performed in the obtained customer service ticket content. Algorithms based on string matching or keyword extraction algorithms in more advanced natural language processing technologies are used to ensure comprehensive scanning and accurate identification of the ticket content.

[0123] Fault report ticket screening and address information processing mainly include screening mechanism and address information extraction and conversion. Fault report tickets containing keywords are screened out from all tickets. These tickets containing keywords are more likely to be directly related to the current fault and are the focus of subsequent location analysis. Customer address information is extracted from the screened fault report tickets. Since address information is usually a natural language description in text format, it needs to be converted into longitude and latitude information through geocoding technology. The fuzzy address description is accurately mapped to the geographic coordinate system to prepare for the subsequent association with the geographic information of the power line.

[0124] Distance calculation and line number determination mainly include spatial data integration, distance calculation algorithm and line number matching. Obtain the geographic information data of the feeder where the power outage event is located, including the starting and ending coordinates of each line segment in the feeder and the line number and other information. Integrate these power line data with the geographic coordinate data of the fault reporting work order customer in the same geographic spatial coordinate system. Use GIS spatial analysis algorithm to calculate the distance between the longitude and latitude of each fault reporting work order customer and each line segment in the feeder where the power outage event is located. According to the distance calculation results, determine the line number closest to each fault reporting work order customer. Set a reasonable distance threshold. When the distance between the customer and a line segment is less than the threshold, the line where the line segment is located is identified as the line related to the fault reporting work order.

[0125] Work order marking and fault analysis mainly include marking process and fault analysis assistance. According to the line number and relative position near the fault report work order found, the customer's fault report work order is marked on the single-line diagram. By marking the fault report work order information on the single-line diagram, the visual fusion of fault information and power system topology is achieved. When the staff uses the single-line diagram to analyze the cause of the fault, they refer to the marked customer fault report work order location and content. The keyword description and location information in the fault report work order can help the staff infer the location and cause of the possible fault. For example, if multiple fault reports are concentrated near a certain line segment and the keywords all point to abnormal sounds, then the possibility of a fault in the line segment is greatly increased, and the staff can focus on inspecting and analyzing the area.

[0126] Accurately selecting and creating keywords related to power failures is the basis of the entire method. These keywords need to cover various possible fault phenomena and related events to ensure that information related to the current fault can be effectively screened out from a large number of fault reporting work orders. At the same time, the keyword library should be continuously optimized and updated according to the actual application situation to adapt to the emerging fault types and characteristics. Through a series of steps and links from work order acquisition, keyword query, data processing to fault location, as well as the relationship and collaborative working mode between each link, the fault reporting work order is accurately marked on the single line diagram, and the staff can make full use of these marked information and work order content to conduct effective fault analysis, so that the staff can quickly understand the relationship between the fault reporting information and the power system, and thus accurately infer the cause and location of the fault. Through in-depth mining and analysis of customer fault reporting work orders, the association model between work order information and fault location is established, which can accurately predict the location where the fault may occur based on various characteristic information in the work order, with high accuracy and practicality.

[0127] In summary, the customer service work order-assisted power fault location method proposed in the present invention can accurately calculate the distance between the user and the feeder line segment, narrow the scope of fault investigation to the specific line segment, and combine the work order keywords and on-site conditions to improve the positioning accuracy, which is better than manual inspection and fault indicator methods. Moreover, the present invention can quickly obtain and filter related work orders from the system, use real-time customer feedback, quickly provide information for fault location, shorten the positioning time, and be more timely than manual inspection. In addition, the automated process in the present invention can reduce manual workload, save labor costs, utilize existing system resources, and do not require a large amount of additional hardware investment, thereby improving resource utilization efficiency. The present invention is also adaptable to a variety of fault types, and can flexibly adjust the work order time range according to the fault situation, which is more adaptable than some specific models or equipment positioning methods.

[0128] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method.
