摘　　要：通过对大型汽轮发电机组在不同失磁故障下的计算分析,着重进行了失磁失步后再同步的条件和措施研究,并对实际系统进行了从失磁到失步以及经控制后再同步过程的全面数字仿真,证实所提出的控制策略是正确的。This paper mades a lot of calculations and analysis on turbo-generators under various loss of excitation faults and emphesizes on the conditions and control strategies of resynchronization after losing excitation and out-of-step. A comprehensive digital simulation of a practical power system is done from losing excitation to out-of-step and then resynchronization via control, which verifies what the paper presents here is correct.
