自并励静止整流励磁系统的励磁调节器是从半导体分立元件向集成化固体组件、从模拟式向数字式方向发展的。国产装置可以划分为半导体模拟式励磁调节器、微机(含可编程控制器)数字式励磁调节器和混合式微机(含可编程控制器)模拟式励磁调节器等三大类。产半导体励磁调节器于70年代初就有出口的记录。微机励磁调节器研制工作始于70年代末。

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个反馈控制系统。

The excitation regulator of self parallel excitation static rectification excitation system has developed from discrete semiconductor components to integrated solid components, and from analog to digital. Domestic devices can be divided into three categories: semiconductor analog excitation regulators, microcomputer (including programmable controllers) digital excitation regulators, and hybrid microcomputer (including programmable controllers) analog excitation regulators. The production of semiconductor excitation regulators has a record of export since the early 1970s. The development of microcomputer excitation regulators began in the late 1970s.

1. Principle of excitation control system
The excitation control system of a synchronous generator generally consists of two parts: an excitation power unit and an excitation regulator. The excitation power unit provides direct current, i.e. excitation current, to the rotor of the synchronous generator; The excitation regulator controls the output of the excitation power unit based on the input signal and given regulation criteria. The entire excitation automatic control system is a feedback control system composed of an excitation regulator, excitation power unit, and generator.
