ABB GFD233A 静态励磁控制器

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。国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。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。国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，1985年南瑞电气公司生产的WLT-1型励磁调节器首次在池潭水电站50MW机组上投入运行。

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. Domestic semiconductor excitation regulators had a record of export in the early 1970s. The development of microcomputer excitation regulators began in the late 1970s.
