Monitoring Method of Overhead Transmission and Distribution Line Operation State Based on WSN Network

Abstract

In order to ensure the safe and stable operation of overhead transmission and distribution lines, the WSN network is used to optimize the line condition monitoring method design. In this paper, considering the connection mode of overhead transmission and distribution lines, a line equivalent model is constructed. The model configures the WSN network through the installation of sensor equipment. The WSN network is used to collect and transmit the operation data of overhead transmission and distribution lines, calculate the monitoring parameters such as voltage imbalance and current detuning, and finally get the visual monitoring results of line status. Compared with the traditional monitoring methods, it is concluded that the monitoring error of voltage imbalance and current detuning by the optimized design method is reduced by 1.15kV and 2.94kA, which effectively improves the monitoring accuracy of line operation.
