摘要

针对电力系统装置相互协调运行问题

对配有PSS的励磁发电机与SVC联合运行的系统

分析了其数学模型

研究了电力系统稳定器（PSS）与静止无功补偿器（SVC）在工厂用电系统近距离联合运行中的交互影响问题

指出了在两者同时运行的情况下SVC控制器的设计需要考虑PSS放大倍数的影响。并提出了设计SVC的比例积分系数和PSS超前滞后环节以及线性二次高斯最优控制方法

动态特性仿真表明可以提高工厂用电系统SVC和PSS的稳定性。最后通过对系统仿真计算从而对理论方法进行了验证。

Abstract

For the problem in the coordinated function of power system equipments

by building a system with SVC and generator excitation with PSS

the authors propose its mathematical model

and analyze the interaction between static var compensator（SVC） and power system stabilizer（PSS）.When SVC and PSS work simultaneously

the system will run into oscillation if the design of SVC controller doesn′t consider the influence of PSS.It is concluded that the system stability is improved when using designing SVC controller and PSS and adopting linear Gauss quadratic optimum methods.Finally lots of experiment results demonstrate the theoretical analysis.
