## 同步发电机励磁控制系统设计+MATLAB仿真

Abstract
Excitation control system is an important part of the synchronous generator, its properties directly affect the reliability of the motor and power system operation and stability.In this paper, by means of simulation of the excitation control system is studied and relevant conclusions are given.This article obtains from the synchronous motor and the excitation system model, the synchronous generator is introduced in detail and the main loop of the excitation system model, and applies the PID controller was carried out on the field current closed-loop control, so as to eliminate the error, the purpose of the recovery system stable state. 源￥自%六:维;论-文'网=www.lwfree.cn
This design using the PID controller, and trial and error method was adopted for the three parameters setting, and to select the optimal parameters are us
ed to control the excitation system.
Finally, this paper used the matlab simulation software for the simulation operation of all kinds of excitation system. MATLAB/SIMULINK platform of its inherent and homemade device model in power system, excitation system simulation model structure, through some necessary parameter Settings excitation system can be realized to the steady state and transient adjustment ability of the power system analysis.
