A Zigbee Network Technology Based Intelligent Monitoring System for Photovoltaic Grid-Connected Inverters
Yunlong Zhou and Guangpiing Lu
An intelligent monitoring of photovoltaic inverters is beneficial for the rapid response to failure in the power generation system. To effectively control and maintain the photovoltaic grid-connected inverters, this study firstly analyzed the monitoring requirements for the photovoltaic grid connection. Then it designed the circuit, power amplifier, monitoring nodes and gateway nodes using the ZigBee network technology, developed the terminal software and, finally, developed an intelligent detection system. The built-up monitoring system was subsequently tested. The testing results demonstrated that the designed intelligent monitoring system, featuring a high flexibility and a good signal transmission quality, could monitor and update the working parameters of photovoltaic grid-connected inverters in real time. It realizes an intelligent monitoring of the works of inverters.
