摘　　要：以500kV五邑变电站为例,对500kV变电站的直流系统进行了详细的统计计算,并按事故全停状态下放电2小时校验,为目前500kV变电站直流系统的选型提供了参考。In this article, taking the DC system of Wuyi Substation to be as an example, the DC system of 500kV substation was calculated in detail. The result was then verified according to its discharging should be kept during 2 hours in case that AC power of whole substation be cut off in an accident. It could be a reference for us to select DC system of similar 500kV substations.

关 键 词：直流系统 计算 校验
