Case name: GPS inspection and management system for power lines in Xinyang Line Work Area
Application time: January 2008
Application product: King Wanma WM-5000PH
Case overview:
Xinyang Electric Power Company’s line work area has more than 50 high-voltage lines under the jurisdiction of 8 counties and 2 districts, with a total length of more than 6,000 kilometers, and the management and maintenance of more than 3,000 power poles.
Each high-voltage power line is inspected by nearly a hundred inspectors from each team in the work area. Different inspection plans can be made for different inspection sections, such as once a month or special inspection once a week. The inspector shall complete the inspection within the specified time period and arrive at the designated inspection road section through walk or car inspection.
Application situation:
The latitude and longitude coordinates collected by GPS can dynamically generate GIS geographic information layers and display the route map. At the same time, the length of the line can be calculated according to the latitude and longitude information of the tower uploaded by the GPS inspection equipment, and the number of the tower and the distance to the two-way substation can be calculated according to the positioning information. According to the type of poles and towers entered, it can automatically determine the number of iron towers, the number of tensile towers, the number of linear towers, the number of cement poles, the number of tensile poles, and the number of linear poles. These data are changed according to the positioning information. When the line changes due to technical or transformation, the repositioning data will be automatically updated. And display the new route map and route map in the GIS.
The tower database can be divided into monthly inspection records, uploaded by the GPS inspection equipment, and statistics of the tower defect records based on the monthly inspection records. The type of the tower is determined by the data, the gear distance is converted to the data by the latitude and longitude, the drawing is called by the line drawing, and the other data is by the height , Tensile section length, salt density, insulator testing, wire connector measurement, special patrol inspection, image data, cross-span measurement, ground resistance measurement, tower tilt measurement, concrete pole crack inspection, steel strand and underground metal parts corrosion Inspection, overhaul and maintenance, external hazard treatment, channel processing, equipment change data screening and generation.
According to the line defects collected by GPS line patrol equipment every month, combined with the input power line basic data and dynamic data such as line maintenance records and equipment change records, real-time operation data of power lines are generated. Integrate GIS, GPS and power line data management to integrate line operation management, maintenance management, data storage and query, forming a complete, efficient and practical new model.
The statistical inquiry part sorts, counts, inquires and prints the operation, measurement, patrol, and overhaul form data of the tower data part according to the route.
The above content constitutes the entire line operation data, which is classified, counted, and printed according to the line. Related information is associated with the database under the line name. Provide a reliable, true and effective basis for the safe and reliable operation and state overhaul of the line.
solved problem:
1. Through the management center located in Xinyang, it is possible to set up all levels of poles and tower sections and inspection lines, and deploy inspection tasks for power lines at all levels.
2. Realize the monitoring of inspectors and achieve the purpose of centralized management.
3. Check the power line resource data to obtain more scientific inspection resource data.
4. It can be combined with the MIS system in the electric power system to conduct inspection inspections and provide various line inspection reports to the upper-level center.
