摘要:

针对光伏组件消防安全问题,设计了一款基于载波通信的消防安全开关。具体对关断器和控制器进行了设计。关断器采集每台光伏组件的电压电流数据,通过电力线载波通信的方式传输至控制器,再经RS-485上传到光伏系统监测平台,实时显示光伏组件的运行状态。通过光伏系统监测平台,或人为按下控制器上的关断按钮,关断光伏组件,即可在发生火灾时,大大降低光伏直流侧高压,从而保障人身安全。

Abstract:

A fire safety switch based on carrier communication is designed to address the fire safety issues of photovoltaic modules.The specific design of the breaker and the controller are carried out.The circuit breaker collects the voltage and current data of each PV module,transmits them to the controller via power line carrier communication,and then uploads them to the PV system monitoring platform via RS-485 to display the operation status of the PV module in real time.In addition,the PV module can be turned off through the PV system monitoring platform or manually pressing the shutdown button on the controller,which can greatly reduce the high voltage on the DC side of the PV in case of fire to ensure the personal safety.

Key words: PV modules, safety shutdown, carrier communication, online monitoring
