摘　　要：随着电力系统的发展,电网调度机构对于电力系统稳定性的要求越来越高,而发电机励磁系统的稳定直接与电力系统的稳定相关,因此确保发电机励磁系统的正常运行十分重要。本文主要对励磁系统二次起励时励磁风机无法正常启动的原因进行分析,并探讨验证优化方案。With the development of power system, power grid dispatching agency has higher and higher requirements for power system stability, and the stability of generator excitation system is directly related to the stability of power system. Therefore, it is very important to ensure the operation of generator excitation system. This paper mainly analyzes the reason why the excitation fan fails to start as usual when the excitation system is excited twice, and discusses the verification and optimization scheme.
