摘要
分析了某电厂由于调速器参数设置的不尽合理,造成雷击线路跳闸后变压器纵差保护误动的事故。特此对低频一、二段保护动作,发电机转子强励动作和变压器纵差保护动作进行分析,提出了如何避免和克服此缺陷的一些建议。
This paper deals with the analysis of the transformer longitudinal differential protection malfunction accident after the line lightning tripping caused by unreasonable setting of governor parameters. And on this basis, the paper offers some suggestions about how to overcome and avoid the mentioned defect.
