摘　　要：研究电网大扰动对ＱＦＳＮ６００ＭＷ汽轮发电机组轴系扭振疲劳寿命损耗的影响，详细研究了机组滑极时的动态行为和机电耦合轴系扭振现象，提出了滑极运行的限制判据。This paper evaluated the fatigue life expenditure of the QFSN 600MW turbogenerator shafts under large power system disturbances. Based on the studies of generator dynamic performance and electro-machanical resonance phenomena under pole slipping operation, the criterion of limiting the pole slipping operation is presented.
