摘　　要：介绍目前在运行智能变电站直流供电系统的现状,由于该直流电源系统在其运行模式切换中还需要人工手工操作来完成,不适应智能变电站发展趋势的需要,因此提出了一种硬件上采用电动、机械式双稳开关,软件上采用顺序控制逻辑的解决方案,实现了直流电源系统运行方式切换的远距离智能操作。Introduces the current status of the DC power supply system of the smart substation currently in operation.Since the DC power supply system needs manual operation to complete the switching of its operating mode,it does not meet the needs of the development trend of smart substations.A method of using electric and mechanical bistable switches in hardware and sequential control logic in software is proposed.The solution realizes the remote intelligent operation of switching the operation mode of the DC power supply system.
