摘　　要：本文论述了已运行的智能变电站直流电源系统的现状。针对这种直流电源系统在运行方式切换时仍需人工手动操作完成,不适应智能变电站发展趋势的要求,提出了硬件上采用电动操作、机械保持的双稳态开关,软件上采用顺序控制逻辑的解决方案,实现直流电源系统运行方式切换的远方智能操作。This paper discusses the current situation of the DC power system in running smart substations.Switching the operation mode of the DC power system must be manually.It can not meet the requirements for smart substation.This paper put forward a solution for remote switching the operation mode of the DC power system.Bistable switch that can be operated by electric and maintained by mechanism is adopted,which is operated by sequential control logic.

关 键 词：智能变电站 运行方式切换 双稳态开关 顺序控制
