介绍了一起110 kV风电场并网线路发生跳闸后,风电场站内进线断路器分闸后又重新合闸的事故.通过仔细分析、判断断路器测控装置、保护装置和开关柜的反复分合,发现防跳回路中存在"寄生"回路.在找到具体原因后,整改了断路器的防跳回路,并针对线路发生跳闸的原因提出相应的整改措施和建议.
介紹瞭一起110 kV風電場併網線路髮生跳閘後,風電場站內進線斷路器分閘後又重新閤閘的事故.通過仔細分析、判斷斷路器測控裝置、保護裝置和開關櫃的反複分閤,髮現防跳迴路中存在"寄生"迴路.在找到具體原因後,整改瞭斷路器的防跳迴路,併針對線路髮生跳閘的原因提齣相應的整改措施和建議.

In this paper, after the trip occurred in 110 kV wind farm grid lines, wind power station in line breaker tripping again after the closing of the accident. In this paper, we analyze the circuit breaker's measuring and controlling device, the protection device and the switch cabinet. After finding out the specific reasons, the anti-jump circuit of the circuit breaker is put forward, and the corresponding rectification measures and suggestions are put forward for the reason of the line trip.
