摘　　要：文中分析了220kV变电站直流系统的几种典型配置，提出基于解析法的变电站直流系统可靠性评估方法；基于所提可靠性评估方法比较220kV变电站直流系统一组蓄电池配置和两组蓄电池配置的可靠性，说明在220kV变电站中应用两组蓄电池配置的必要性。Several typical schemes of 220kV substation DC system are analyzed. A method for reliability evaluation based on analytic method is proposed. Based on this method, the reliability of one VRLA group and two VRLA groups configuration for 220kV substation is compared, showing the necessity to take two VRLA groups configuration.
