摘要
针对矿井10 kV供电系统经常发生单相接地故障而导致系统过电压现象,文章以Matlab仿真平台为基础,重点分析了金属性接地和弧光接地2种单相接地故障的特点,建立了仿真模型,进行了数字仿真,并给出了故障波形和数值结果。
Aiming at over voltage phenomena of 10 kV power supply system of mine because of single-phase to ground fault, the paper took Matlab simulation platform as base, emphatically analyzed performances of metal grounding fault and arc grounding fault. It built simulation model and carried out digital simulation, and gave fault waveforms and numerical results.
