数字式远方备自投装置

数字式远方备用电源自动投入装置可以同时运行在电网中几个有联络线联系并由两个主电源供电的变电所中．几个变电站中的远方备自投装置采用RS-485通信方式．站与站之间通过光纤通道联系在一起．光纤中传输的其他各站信息参与本站的备自投逻辑判断，这就使几个变电站形成一个网络化的备自投系统．大大提高了供电可靠性．介绍了数字式远方备自投装置的系统结构及工作原理．该装置采用逻辑可编程技术可在远备投装置中装载多套逻辑程序，针对不同的一次主接线方式只需选择相应的控制字即可．无需修改硬件电路，适用性更好。目前该装置已投入使用。

Digital remote automatic bus transfer equipment

Digital remote automatic bus transfer equipment can be applied in interconnected substations supplied with two main power sources in the same time. The digital remote automatic bus transfer equipment in substations adopts RS-485 communication mode via optical fiber,and the information from other substations is involved in local logic judgment. A networked automatic bus transfer system is thus formed and improves the reliability of power supply. Its systematic structure and working principle are introduced. With multiple logic programs loaded by technology,only the control word need to be set according to different primary main The equipment has been put into operation. using PLC connections.
