基于 DSP 的开关式励磁调节器的设计

摘要

励磁调节器是励磁控制系统的重要组成部分,直接影响电机及电力系统特性。随着大
规模集成电路技术及计算机技术的发展,采用微处理器作为硬件控制核心的微机励磁调节
器将成为今后主要发展方向。随着励磁控制方法的不断改进与发展,对微机励磁调节器的
运算速度和处理能力提出了非常高的要求。DSP(数字信号处理器)具有高速、卓越的数
字信号处理能力以及丰富的外部扩展功能,使其应用领域从通信行业拓展到工业控制领
域。本文就是在这种背景下,设计和实现以 DSP 为控制核心的开关式励磁调节器。
文中首先介绍了开关式励磁调节器的原理及其基本理论依据,然后论述了 DSP 励磁
调节器的硬件和软件的组成。在硬件组成中,详细地介绍了 DSP 励磁调节器的硬件组成
部分,其中有 DSP 外围电路的设计,数字电路和液晶模块的设计。同时,该励磁调节器
的所有功能均通过软件实现,采用 C 语言和 DSP 汇编语言混合编成的方法,这既保证了
软件具有 C 语言结构清晰易读、开发周期短的特点,同时又使整个软件具有较高的效率。
该文采用 PID 控制技术设计了同步发电机励磁调节器,整体仿真试验结果表明该励磁控
制器有较完善的控制功能及较好的调节品质。

DESIGN AND DEVELOPMENT
ON THE SWITCH-EXCITATION
REGULATOR BASED ON DSP

ABSTRACT

Excitation system is an important part of synchronous generator. And it affects the
operating characteristics of generator and power system directly. With the development of the
large-scale integrated circuit puter technology, the excitation regulator in which the
microprocessor is the ponent will be the trend in the future. With the improvement and
development in excitation's control method, the higher request in operation and calculation
ability of excitation regulator is put forward. DSP (digital signal processor), which has
high-speed, remarkable ability in digital signals processing and abundant external expanded
function, make its application expand munication trade to the industry-controlled field.
Under this background, this thesis studies the design and implement of switch-excitation
regulator for synchronous generator based on DSP.
In the paper we introduced the origination of the switch-excitation regulator and its principle
mathematic analysis method firstly. Then explain the software and hardware on the excitation
regulator. In the hardware of system, it introduces the detailed hardware of DSP excitation
regulator, including the design of DSP peripher
