摘　　要：在大型发电机组停机过程中,操作不当或保护配置不合理,不仅会损坏机组本身,也会对电网产生严重的影响。针对大型机组停机过程中广泛采用的程序跳闸停机方式,对大型机组保护中用于程序跳闸的保护配置进行了分析,对几种保护配置进行了对比,提出了针对性的建议。In process of the large generator set shut down,if operate not appropriate or the protection install not reasonable,not only damage the generator set,also to bring about seriously influenc for the electrical network.This paper aims at the large generator set shut down the process in the extensive adoption of procedure trip to shut down the way,is convenient to trip in the procedure to the large generator set protect of protection configuration were analysed,a few protections configuration was contrasted and put forward in the light of suggestion.
