基于低压窄带电力线载波通信技术对微型逆变器监控系统进行设计,该系统由监控中心、电网电压采集终端和微型逆变器采集控制终端三部分组成,主要对载波通信采集模块、继电器控制模块及监控软件进行设计开发.实验搭建的监控系统实现了对微型逆变器运行参数实时监控、单体光伏组件故障检测以及电量过剩检测等功能,通过由监控中心控制的继电器来控制微型逆变器工作状态,有效避免光伏发电系统对电网质量的影响.
Based on the low-voltage narrow-band power line carrier communication technology, the micro-inverter monitoring system is designed. The system consists of monitoring center, power grid voltage acquisition terminal and micro-inverter acquisition control terminal. The system mainly consists of three parts: the carrier communication acquisition module, the relay control module Monitoring software to design and develop.The experimental set up monitoring system to achieve real-time monitoring of micro-inverter operating parameters, single PV module fault detection and over-power detection and other functions, controlled by the control center relay to control micro-inverter work State, effectively avoid the impact of photovoltaic power generation system on the grid quality.
