摘要
针对发电厂高压厂用电系统的特点,分析了发电厂高压厂用电系统中性点接地方式选择的基本要点,介绍了一种先进的新型接地方式——快速消弧加快速选线,并结合广东某电厂9#机组的运用,阐述这种接地方式的可行性。
In the light of the feature of power station auxilary power supply systems,the basic selection point of conventional neutral point grounding way are analyzed, and a new advanced neutral point grounding way with fast arc-supression coil plus fault location is described. Test results of 9# power station auxilary power supply systems at one Guangdong Power Plant show that the new neutral grounding mode is feasible.
