摘　　要：大坝发电有限公司#4机自1999年经进相运行试验后,已成为调整西北330kV电网无功和电压的主力机组。现结合实际运行情况,对#4发电机进相稳定运行区域,进相运行与失磁失步、进相运行与定子铁心及端部过热、进相运行与自动励磁调节器等关系作了分析。对厂用电电压的限制问题也作了讨论。最后提出了运行人员在发电机进相运行中应注意的安全事项。Analyzes the area of No.4 unit leading phase steady operation, the relations of leading phase operation with loss of excitation and synchronism, with stator core and top overheating, with excitation regulator. Discusses electricity using voltage limit in power plant. Finally puts forward safety attentions should be noticed by operators during generator leading phase operation.
