摘要
利用PLC技术设计地铁变电站自动化系统,提出了系统结构及特点,系统中采用分散式控制,简化了系统结构,总线技术,通讯技术构建了一个高可靠性的变电站自动化系统。
Using PLC technology, we completed a Metro substation automation system. The system cut down a large amount of wire by the technology of PLC bus and communication. A simple frame system of substation automation come true, based on distributed control.
