A centralized monitoring and analysis system of transmission lines in mined-out area

The centralized monitoring and analysis system of transmission lines in mined-out area is based on the indicators of state variables which reflect the health state of the transmission lines in mined-out area. This system uses this pattern which combines transmission tower body with overhead lines, and makes use of the equipment management model and technical measures to manager. It conducts the real-time monitoring for transmission lines in mined-out area by the means of online monitoring. The system can utilize the exploration data, basic grid data and online monitoring data in mined-out area to execute state analysis and safety assessment for the transmission tower body and overhead lines, and provide timely warning when the state of equipment is deteriorating or the trend is adverse. Besides, it can analyze the mode and cause of malfunction. In this way, the system can provide decision support to the repair of transmission equipment and the maintenance of lines, and optimize maintenance management, finally realize safe and economic operation of the grid in mined-out area.
