摘　　要：某供电局所辖部分110kV变电站使用的GZDW34-300(280、450)/220-M型直流系统,在实际运行中,其控制母线上出现了高达310～390V不等的过电压。针对控制母线强过电压的现象,探讨故障的引发原因,提出消除方法。Overvoltage on control bus was ever found while using the DC equipment of GZDW34-300 （280, 450）/220-M at operating substation. As is known, control bus is the core of DC equipment. Monitoring and control may be disabled with a control bus fault, and this will extremely reduce the operation reliability of substation, even cause disastrous accident to power system. So, it＇s obviously necessary to eliminate overvoltage on control bus.
