摘要
介绍了配电网的3种接地方式(不接地、经电阻接地、谐振接地),分析了不同接地方式的原理和特点,利用ATP-EMTP仿真软件对35kV配电网的接地方式进行了仿真比较,指出了中性点经消弧线圈并联大电阻接地方式是目前比较好的接地方式。
The paper introduces the three grounding modes of distribution network,namely the non-grounded mode,the neutral grounding mode via resistance and the neutral grounding mode via arc suppression coil. The principle and characteristic of each grounding mode is analyzed. The several grounding modes of 35 kV distribution grid are simulated and compared by the ATP-EMTP software, and the neutral grounding mode via extinction coils in parallel connection with big resistances is indicated as a good mode at present.
