Research on monitoring terminal system of substation auxiliary facilities based on wireless sensor network

Aiming at the problems such as low intelligence degree, poor linkage and mis-operation or rejection in remote control of substation auxiliary facilities, a design method of substation auxiliary facilities monitoring system based on WSN (Wireless Sensor Network) is proposed. Firstly, the problems existing in the existing monitoring terminal system are analyzed. Secondly, WSN architecture is transformed into ZigBee wireless communication network, z-stack protocol stack is used for wireless data sending and receiving, and hardware and software of monitoring terminal system are designed. Finally, build the system test platform. The experimental results show that the system can respond quickly to the complex situation in the substation and effectively improve the monitoring efficiency of the substation auxiliary facilities, which verifies the stability and practicability of the system.
