摘　　要：鉴于达岱河水电站由于短路引起的增量差动保护动作,从主变压器增量差动的原理、现场故障录波器波形记录等方面对故障的原因进行了分析,提出了解决方案,实践表明其解决方案是有效的。In the Tatay Hydropower Station, incremental differential protection action of the main transformer is observed due to short circuit.Possible reasons of this fault are investigated with an analysis on the in-situ fault recording data. Corresponding treatment measures are then proposed.Practice shows that the measures are effective.
