摘　　要：在电力系统的运行中,同步发电机的励磁系统起着重要的作用。其不仅维持发电机或系统的电压水平,合理分配发电机间的无功负荷;而且可以提高电力系统的静态稳定性和动态稳定性,并且能够在发电机内部出现故障时进行灭磁,降低故障损失程度;同时能够根据运行要求使发电机实行最大励磁限制及最小励磁限制。文中对励磁系统进行了概述。In the operation of power system,the excitation control system of synchronous generator plays an important role.It not only maintains the voltage level of generator or system,reasonably distributes reactive load and power factor between generators,but also improves the static and dynamic stability of power system,and can de excite in case of internal fault of generator,Reduce the degree of fault loss,and enable the generator to implement the maximum excitation limit and minimum excitation limit according to the operation requirements.This paper gives a brief overview of the excitation system.
