摘　　要：针对部分负荷较重地区的变电站常使用三进线,无法实现母线恢复供电,提出新型备自投逻辑控制策略,在一条线路无法带动三台主变运行的基础上,可以最大限度实现母线的恢复供电。In view of the fact that three incoming lines are often used in substations in some heavily loaded areas, which can not restore the power supply of the bus, this paper proposes a new standby automatic switching logic control strategy, which can maximize the restoration of the power supply of the bus on the basis that one line can not drive the operation of three main transformers.

关 键 词：扩大内桥 备自投 逻辑控制策略
