Abstract

The invention discloses a power transmission line online monitoring system adopting distributed power supply. The system includes a field monitoring terminal, a communication network and a control center. The field monitoring terminal is intended for real-time acquiring operation state of a power transmission line, transmitting the acquired operation state of the power transmission line to the control center through the communication network. The control center is intended for computing, analyzing and storing the received operation state of the power transmission line. The field monitoring terminal includes a field monitoring mainframe, a monitoring unit and a power supply unit. The field monitoring mainframe includes a data acquisition circuit, a micro-processor, a storage unit, a first wireless communication module, a second wireless communication module, a communication switch module and a power supply interface circuit. According to the invention, by monitoring the operation state of the power transmission line through the field monitoring terminal and transmitting the acquired operation state of the power transmission line to the control center through the communication network, the system realizes remote monitoring of the power transmission line, lowers labor intensity, and ensures safe operation of the power transmission line.

Description

technical field [0001] The invention relates to a transmission line monitoring system, in particular to an on-line monitoring system of a transmission line using a distributed power supply, which belongs to the technical field of on-line monitoring of transmission lines. Background technique [0002] my country's power grid covers a wide area, and the distance of transmission lines is long. The total length of transmission lines with a voltage level above 110KV exceeds 600,000 kilometers. The impact of uncertain factors such as man-made damage (theft, destruction) has always been the main factor threatening the safe operation of the power grid. Therefore, how to effectively guarantee the safety and reliability of the power system has always been an important issue for power companies. Monitoring the transmission lines and grasping various operating parameters of the transmission lines in real time is the premise of realizing the condition-based maintenance of power equipment...
