摘　　要：兴安直流的极控与直流站控均采用冗余配置,但其控制和状态数据是由单重化配置的光耦继电器与硬接线组成回路连接至其他控制保护装置的。通过分析极控与直流站控的各类单一元器件发生故障时可能导致的后果,提出针对这些隐患的整改方案,并在方案实施前后进行试验,验证整改效果。The pole control and DC station control of Xing′an DC adopt redundant configuration,but its control and status data are composed of single configuration optocoupler relay and hard wiring,which are connected to other control and protection devices.By analyzing the possible consequences of the failure of various single components of pole control and DC station control,a rectification plan for these hidden dangers was proposed,and tests were conducted before and after the implementation of the plan to verify the rectification effect.

关 键 词：极控 直流站控 冗余
