500kV单相变压器组中性点接地方式探讨

Discussion on the Neutral Grounding Modes of 500 kV Single Phase Transformer Set

分析了500kV单相变压器组中性点汇流母线3种接地方式的优缺点,认为中性点汇流母线采用一端两点接地的方式较为合理,并对运行维护提出了建议。

On the basis of analyzing the merits and demerits of different neutral grounding modes of 500 kV single phase transformer set, it is recommended that the reasonable neutral grounding mode be grounding the neutral busbar with two points at one terminal. Some proposals for operation and maintenance are also put forward in this paper.
