摘要
中性点直接接地电网的输电线接地保护方式，如果不计纵联保护在内，基本上只有零序保护与接地距离保护两种。本文根据实际情况说明两种情况的优劣，提出改善变压器零序保护配合的措施。
The neutral grounding power of the transmission line directly to ground protection,if not total protection,including the pilot,basically only the zero-sequence protection and the protection of both ground distance.Based on the description of the actual situation in the merits of both cases,to improve protection of the transformer zero-sequence complementary measures.
