摘要
Abstract
220kV transformer is one of the most importance parts of power grid.The strong short-circuit current causing great threat to the safety of transformer when it occurs a single-phase short.Instal ing a low reactance on the neutral point of transformer is an effective way.This paper lists four neutral grounding moods of 220kV transformer and introduces how to choose the magnitude of low reactance in different neutral grounding moods. At last we use PSCAD to simulate the affect to short-circuit current and give the best way to limit it.关键词
