| 摘 要： | 在PSCAD软件中建立中性点经消弧线圈接地系统的仿真模型,利用两段电缆之间设置单相接地故障模拟电缆绝缘损伤造成的单相接地故障,通过对中性点不接地系统和经消弧线圈接地系统分别进行仿真,比较接地点故障电流和故障线路的负荷端电压、电流波形。通过仿真验证了消弧线圈对减小接地点故障电流所起的明显作用,降低了接地电流带来电弧的幅值,避免了不必要的自动跳闸,提高了供电的可靠性,为煤矿的安全生产带来保证。

| Abstract: | The simulation model of neutral point arc suppression coil grounding system is created in the PSCAD software,using the single-phase ground fault setting between two cables to simulate single-phase grounding fault caused by cable insulation damage.Through the simulation of neutral none-grounding system and the art suppression coil grounding systems,compare the grounding fault electric current and the load side voltage and current waveforms of fault line.By simulation to prove the obvious effect of reducing g... |
