摘要
设计了一种光伏并网发电通信控制器。通过RS-485口采集各组光伏发电单元及其他设备的模拟量参数,计算光强、直流电压和电流进行逆变辅助控制,对自动跟踪各单元进行一致性控制,并利用检测风速对自动跟踪各单元进行保护控制。采集计算系统运行参数,供检测系统显示和分析。该通信控制器还具有基于Modbus协议的远方通信功能。
A PV grid-connected power generation communication controller was designed.The analog parameters of each generation cell and other devices were collected by RS-485 port.The inverter aid control was carried out by reckoning light intensity,DC voltage and current.The wind speed was also be detected to protect tracking units.The system operating parameters were collected and computed to be analyzed and shown.This controller can realize remote communication function based on Modbus protocol.
