1.励磁控制系统的原理

同步发电机的励磁控制系统一般由励磁功率 单元和励磁调节器两部分组成，励磁功率单元向同步发电机转子提供直流电流，即励磁电流:励磁调节器

根据输入信号和给定的调节准则控制励磁功率单元的输出。整个励磁自动控制系统由励磁调节器、励磁功率单元和发电机构成的一一个反馈控制系统。

1. Principle of excitation control system

The excitation control system of synchronous generator is generally composed of two parts: excitation power unit and excitation regulator. The excitation power unit provides DC current to the rotor of synchronous generator, that is, excitation current: excitation regulator

Control the output of the excitation power unit according to the input signal and the given regulation criteria. The whole excitation automatic control system is a feedback control system composed of excitation regulator, excitation power unit and generator.
