发电厂高压厂用电系统接地问题探讨

Discussion on the Problems of High Voltage Auxiliary Supply System for Power Plant

发电厂高压厂用电系统中性点接地方式有不接地、经消弧线圈接地和经电阻接地等,各种方式各有其优缺点.目前,我国这几种方式都有应用,但具体采用哪种方式还要视电厂的实际情况而定,以保证发电厂厂用电系统安全运行.

In station, neutral grounding modes of high voltage auxiliary supply system are isolated neutral,grounding by resistance or grounding by arcsuppression coil and etc., each mode bearing different advantages and defects. At present,all these modes are applied in China. But the choice of proper mode depends on the actual instance in Power Plant so as to make sure the auxiliary supply system is operated safely.
