摘　　要：本文针对直流级差配合的难题开发了直流开关级差配合分析算法,并将该算法整合到直流开关在线监测系统中,可自动识别在发生故障时开关的所处状态。同时对该系统的可靠性进行验证,可有效分析直流开关的运行状态,解决了因级差配合误动的难题。For the problem of DC stage difference coordination,an analysis algorithm of DC switch stage difference coordination coordination is developed. The algorithm is integrated into the on-line monitoring system of DC switch,which can automatically identify the state of the switch in case of fault. At the same time,the reliability of the system is verified,which can effectively analyze the operation status of the DC switch and solve the problem of misoperation due to stage difference.
