摘 要: 煤矿电网中由于单相接地引起的各类故障时有发生,根据某煤矿电网的运行情况,结合事故记录,对其进行仿真分析。判断出该矿消弧线圈无法正常投入运行的原因是接地时局部电网构成了谐振回路,从而引发了电压互感器的铁磁谐振,直至烧毁。从诸多解决铁磁谐振的措施中选取2种方式进行仿真研究,找出合理可行的解决措施。

Abstract: The single-phase fault sometimes happens in coal mine power network. Based on the realistic run of a coal mine power network, and combined the accident record, the simulation and analysis was carried out. The arc suppression coil couldn’t launch normally because when grounding fault happened, the part network made up the resonance loop, then resulted in the ferroresonance. Two measures were chosen from some measures of restraining ferroresonance to simulate and find the reasonable and viable restraining method.
Key words: power supply for coal mine; coal mine power network; ferroresonance; simulation
