基于MATLAB的同步发电机PSS与励磁系统仿真

摘要

The paper study the power system stabilizer(PSS) for the auxiliary control of the synchronous generator excitation control on the base of the analysis of synchronous generator excitation control system model And the excitation control system simulation model including PSS is established based on MATLAB/SIMULINK. By setting power system fault such as the three phase short circuit and disconnection fault to analysis the excitation control system' control performance with PSS according to the simulation results,and compare the result with the excitation system without PSS. At last obtained the necessity of loading PSS in the synchronous machine excitation system, and provided the basis for the design of excitation system.%在分析同步发电机励磁控制系统模型的基础上,研究了以电力系统稳定器(Power System Stabilizer-PSS)为辅助控制的同步发电机励磁控制方式,并基于MATLAB/SIMULINK构建了包含PSS的励磁控制系统的仿真模型.根据仿真结果分析在电力系统出现不同故障(三线短路以及断线故障)情况下带有PSS的励磁控制系统的控制性能,并与不加载PSS的励磁系统进行了比较,得到了在同步机励磁系统中加载PSS的必要性,为励磁系统的设计提供了依据.
