摘要
同步发电机在运行时,必须在励磁绕组中通入直流电流,以便建立磁场,这个电流称为励磁电流,而供给电流的整个系统称为励磁系统。本文从四个方面分析了同步发电机的任务。
In running time, DC current of Synchronous generator must be passed into the field in order to establish the magnetic field. This current is called the exciting current, while the supply current of the entire system is called excitation system. In this paper, the task of synchronous generator is analyzed in four aspects.
