中文摘要：
根据配电线路无通道保护的特点,设计了新型备自投低压模块的启动判据和动作时间,使非故障失电线路区段的供电恢复时间最大限度减小;在投入到永久性故障再次断开时,备自投的一合一开2次扰动为对侧保护的过电流加速（AOC）模块在加速时间窗内提供电流变化量,可以从电源侧加速切除故障。实时数字仿真实验验证了整套方案的有效性。
英文摘要：
According to the characteristics of non-communication protection for distribution line,the startup criterion and operation time of UV（Under Voltage） module are redesigned for a new kind of automatic switchover device to minimize the power recovery time.When the automatic switchover device responds to a permanent fault,two disturbances caused by its close and open operations induce the current variation within the speed-up time window of the AOC（Accelerated Over-Current） module of the protection at opposite side,which accelerates the removal of fault at source side.Real-time digital simulation verifies the effectiveness of the proposed scheme.
