Automatic Monitoring Method of Relay Protection State of Thermal Power Plant Generator Set Based on Wireless Sensor Network
In order to enhance the effect of relay protection status monitoring,the research on automatic monitoring method of relay protection status of thermal power plant generating units based on wireless sensor network is proposed.Firstly,LoRa sensor is used as the acquisition device of target data,and the data is sent to the monitoring management center in the form of LoRa wireless signal with the help of LoRa gateway.Then,using the linkage between different data of relay protection,the XOR logic for the relay protection of thermal power plant generator units is constructed,and the nonlinear parameters when the Boolean parameters of relay protection are inconsistent are taken as the abnormal monitoring output results.The results show that the design method has small error and high stability,and the application effect is good.
