铁路10kV配电室馈出线保护误动原因分析及处理

Analysis and Solution to the Malfunction of Feeder Line in Railway 10kV Power Distribution Station

以京广线高邑配电室馈出线保护误动跳闸问题为例,分析了产生这一问题的原因,通过对各种故障序网构成的阐述,找到了故障发生时刻电压、电流的变化规律,提出了在不增加设备的前提下、优化保护动作逻辑来避免发生保护误动问题的方案,讨论了其可行性。

Regards feeder line false action of Gaoyi power distribution station in Beijing-Guangzhou railway as the example,and analyzes to produce the reason of this problem,according to the fault network,finds out the variation of the voltage and current,proposes the solution of optimize actuating logic under the situation of doing not increase primary equipment,and discusses its possibility.
