Description

Technical Field

[0001] This invention relates to the field of power grid technology, specifically to a remote safety management method and system for substation operation and maintenance. Background Technology

[0002] A substation is a location in a power system that transforms voltage and current, receives electrical energy, and distributes it. Substations within power plants are step-up substations, whose function is to step up the voltage of the electricity generated by generators before feeding it into the high-voltage power grid. Substation operation and maintenance is a complex and crucial process, encompassing inspection, equipment maintenance and repair, operation management and control, safety management, and many other aspects. Substation inspection involves on-duty personnel periodically observing the equipment for any abnormalities, such as color changes, the presence of foreign objects, whether meter readings are normal, whether the equipment sounds normal, whether there are any unusual odors, whether the temperature of permissible contact equipment is normal, and measuring changes in the operating parameters of electrical equipment during operation to determine if the equipment is operating normally.

[0003] In existing technologies, the inspection process typically involves regular patrols by on-duty personnel to understand the equipment's operating status, identify any abnormalities, and take timely measures. This is crucial for reducing the occurrence and impact of accidents. Therefore, substations should develop specific inspection methods based on the actual operating conditions of the equipment and lessons learned from past incidents, malfunctions, and defects. However, in large cities or industrial areas, with the continuous expansion of the power grid and increased electricity demand, multiple substations are needed in different areas to ensure stable power supply and distribution. This leads to significant pressure and numerous tasks in equipment maintenance and repair, greatly increasing the manpower and material resources required for inspections. Consequently, it becomes impossible to comprehensively cover all substations during inspections, hindering the timely detection of abnormal equipment operating conditions. Therefore, to address these issues, this invention provides a remote safety management method and system for substation operation and maintenance. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a remote safety management method and system for substation operation and maintenance;

[0005] The objective of this invention can be achieved through the following technical solution: a remote safety management system for substation operation and maintenance, comprising a management center, wherein the management center is wirelessly connected to a monitoring and acquisition module and a safety management module; the management center includes a data processing unit, a visualization unit and a remote control unit;

[0006] The monitoring and acquisition module is equipped with a generation unit and an acquisition unit; the generation unit is used to generate the inspection and monitoring route and monitoring content and send it to the acquisition unit; the acquisition unit is used to collect data on the substation area in real time according to the inspection and monitoring route and monitoring content, obtain operation and maintenance data packets and send them to the management center.

[0007] The data processing unit is used to set up an identifier-instruction dataset library, process each piece of operational data in the operational data package, obtain abnormal operational data, identify the abnormal operational data according to the identifier-instruction dataset, and obtain the corresponding instruction; the visualization unit is used to obtain the abnormal operational data table corresponding to the abnormal operational data; the remote control unit is used to set up the management center access permission library.

[0008] Each management terminal in the sub-management terminal network receives the abnormal operation and maintenance data table, obtains the location of the abnormal operation and maintenance, processes it to obtain the equipment defect record table, and sends it to the central security management terminal; the central security management terminal accepts the equipment defect record table according to the management center's access permissions and obtains an acceptance report.

[0009] Furthermore, the process by which the generation unit generates the patrol monitoring route and monitoring content includes:

[0010] Each substation area is divided into dynamic monitoring areas and static monitoring areas. The dynamic monitoring area includes a main control sub-area, an auxiliary control sub-area, and an environmental sub-area. The static monitoring area includes a line sub-area and an outdoor equipment sub-area. The monitoring parameters corresponding to all sub-areas in the dynamic and static monitoring areas are acquired, and the monitoring parameters corresponding to each sub-area are used to generate corresponding parameter nodes for real-time collection of operation and maintenance data corresponding to the monitoring parameters. Then, the corresponding sub-area inspection and monitoring routes are generated sequentially.

[0011] Each substation area is labeled, and the sub-areas corresponding to each substation area are numbered in the order of main control sub-area, auxiliary control sub-area, environmental sub-area, line sub-area, and outdoor equipment sub-area, and are referred to as sub-areas.

[0012] According to the order of sub-regions, the inspection and monitoring routes of each sub-region corresponding to the dynamic monitoring area and the static monitoring area are connected end to end to generate the corresponding dynamic main inspection and monitoring route and the static main inspection and monitoring route, and then connected end to end to generate the inspection and monitoring route corresponding to each substation area.

[0013] Each management terminal in the sub-management terminal network is equipped with a monitoring content generation port. The monitoring content generation port is equipped with a selection port and a generation port. The selection port includes an area selection port, a patrol monitoring route selection port, and a monitoring parameter selection port. The substation area is selected, and the corresponding patrol monitoring route and corresponding monitoring parameters are selected according to the substation area, and then sent to the generation port to generate the corresponding monitoring content.

[0014] Furthermore, the process by which the acquisition unit obtains the maintenance data package includes:

[0015] The system acquires the substation area from the monitoring content, and schedules the operation and maintenance data corresponding to the parameter nodes in real time according to the corresponding inspection and monitoring route and the corresponding monitoring parameters. It also integrates the corresponding operation and maintenance data according to the inspection and monitoring route to generate the corresponding operation and maintenance data package.

[0016] Furthermore, the process by which the data processing unit acquires abnormal operation and maintenance data includes:

[0017] Set corresponding identifiers for the monitoring parameters of each sub-region, and set the corresponding monitoring parameters as the instructions corresponding to the identifiers. Then, map the identifiers and instructions corresponding to the monitoring parameters to generate corresponding identifier-instruction datasets, and merge the various identifier-instruction datasets to generate an identifier-instruction dataset library.

[0018] The same monitoring parameters are integrated to generate the same monitoring parameter package, and then the identifiers corresponding to each monitoring parameter in the same monitoring parameter package are obtained; based on big data, the operation and maintenance data threshold ranges corresponding to different identifiers in the same monitoring parameter package are obtained, and data mapping is performed with the monitoring parameters to generate an identifier-operation and maintenance data threshold set.

[0019] Retrieve all monitoring parameters from the operations and maintenance data package, and simultaneously send the monitoring parameters to the corresponding identifier—the operations and maintenance data threshold set. Then, based on the corresponding identifier, obtain the corresponding operations and maintenance data threshold range and compare it with the operations and maintenance data corresponding to the monitoring parameters.

[0020] If the operation and maintenance data does not fall within the operation and maintenance data threshold range, the corresponding operation and maintenance data will be marked as abnormal operation and maintenance data, and the corresponding identifier will be marked as an abnormal identifier; otherwise, no action will be taken.

[0021] Furthermore, the process by which the visualization unit acquires abnormal operation and maintenance data charts includes:

[0022] Obtain the anomaly identifier corresponding to the abnormal operation and maintenance data, and obtain the monitoring parameters, substation area and sub-area corresponding to the abnormal data based on the anomaly identifier, and then obtain the abnormal operation and maintenance data table;

[0023] The abnormal operation and maintenance tables obtained from each management terminal are summarized to obtain the number of abnormal operation and maintenance data corresponding to the same abnormality identifier. Then, based on the number of abnormal operation and maintenance data, a historical abnormality identifier pie chart is generated from the abnormal operation and maintenance tables.

[0024] Furthermore, the process of setting the access permission library for the management center by the remote control unit includes:

[0025] The access permission database in the management center includes a permission database and a scheduling database. The permission database includes access accounts, access names, and access management terminal MAC addresses; the scheduling database includes scheduling access management terminal MAC addresses and scheduling instructions.

[0026] Furthermore, the process of obtaining the equipment defect record table includes:

[0027] The abnormal operation and maintenance form is sent to the corresponding management terminal. The management terminal receives the corresponding abnormal operation and maintenance data, obtains the area location based on the substation area and sub-area, obtains the abnormal operation and maintenance processing location based on the monitoring parameters, processes the abnormal operation and maintenance data based on the abnormal operation and maintenance processing location, obtains operation and maintenance processing data, and then obtains the equipment defect record form.

[0028] Furthermore, the process of obtaining the acceptance report includes:

[0029] The central security management terminal receives the device defect record form. The central security management terminal is equipped with an input port. The access account, access name and access management terminal MAC address are entered into the input port and sent to the remote control unit. The data is then matched with the permission database. If all matches are successful, the user can enter the management center; otherwise, the user cannot enter the management center.

[0030] Upon entering the management center, the system uses the identifiers corresponding to the monitoring parameters in the equipment defect record table to retrieve the corresponding operational data for that specific monitoring parameter, which is then recorded as follows: The system then compares the current operational data with the operational data threshold range. If the data falls within the operational data threshold range, it compares it with operational processing data b. If the data meets the threshold, the operation and maintenance processing data will be marked as normal; otherwise, it will be marked as abnormal. If there is no threshold range for operation and maintenance data, the operation and maintenance processing will be marked as abnormal.

[0031] Generate a normal acceptance report or an abnormal acceptance report for each normal or abnormal report and send it to the management terminal corresponding to the MAC address of the access management terminal; if an abnormal acceptance report is received, it needs to be processed again until a normal acceptance report is received; otherwise, do not perform any processing.

[0032] Furthermore, this includes the following steps:

[0033] Step 1: Set up the inspection and monitoring route and monitoring content, and collect data in real time on the substation area according to the inspection and monitoring route and monitoring content to obtain operation and maintenance data packages;

[0034] Step 2: Set up the identifier-instruction dataset library and the management center access permission library, process each operation and maintenance data in the operation and maintenance data package, obtain abnormal operation and maintenance data, identify the abnormal operation and maintenance data according to the identifier-instruction dataset, and obtain the instruction corresponding to the abnormal operation and maintenance data; then obtain the abnormal operation and maintenance data table corresponding to the abnormal operation and maintenance data.

[0035] Step 3: Receive the abnormal operation and maintenance data table, obtain the location of abnormal operation and maintenance, and process it to obtain the equipment defect record table; then, according to the access permissions of the management center, accept the equipment defect record table and obtain the acceptance report.

[0036] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention sets up inspection and monitoring routes and monitoring content, and collects data on the substation area in real time according to the inspection and monitoring routes and monitoring content to obtain operation and maintenance data packages; it sets up an identifier-instruction dataset library and a management center access permission library to process each operation and maintenance data in the operation and maintenance data packages to obtain abnormal operation and maintenance data, and then identifies the abnormal operation and maintenance data according to the identifier-instruction dataset and obtains the instructions corresponding to the abnormal operation and maintenance data; then it obtains the abnormal operation and maintenance data table corresponding to the abnormal operation and maintenance data; then it receives the abnormal operation and maintenance data table, obtains the abnormal operation and maintenance processing location, and processes it to obtain an equipment defect record table; then it accepts the equipment defect record table according to the management center access permission and obtains an acceptance report; this invention effectively improves the coverage of substation inspections.
