摘　　要：柔性交流输电系统(FACTS)技术的出现,为提高电网的可控性与可靠性提供了更新更有效的方法,已经成为近年来电力系统所研究的前沿课题之一。静止无功补偿器(SVC)和可控串联补偿器(TCSC)做为FACTS装置中应用最广泛的重要组成成员,是提高电力系统稳定性最有效的工具。因此,研究SVC与TCSC在电力系统中的应用具有非常重要的理论意义和实用价值。本文研究TCSC、SVC的特性,推导出它们的参数模型。通过Matlab软件,建立了SVC与TCSC两种FACTS装置的仿真模型。TCSC为串联补偿装置,通过连续改变其等效阻抗,从而改变输电线路上的串补程度;SVC为并联补偿装置,改善系统的功率因数。通过改变晶闸管的触发角,对晶闸管进行控制。The emergence of Flexible AC Transmission Systems technologies,becomes a new method of improving the controllability and reliability of power system,which is one of the frontal subjects of power system in recent years.Thyristor Controlled Series Compensator（TCSC） and Static Var Compensator（SVC） are the important elements of FACTS and useful tools to improve the power system stability.The research on TCSC and SVC to the power system has significant theoretical meaning and practial value.This paper studies TCSC,SVC characteristics then the parameters of the model are derived.Simulation model is done in Matlab and set up two kinds of FACTS devices SVC and TCSC simulation model.TCSC as the series compensation,can successively changes the equivalent impedance.then change the level of the series compensation.SVC as a parallel compensation which improving system power factor.By changing the triggering angle of the thyristor to control of the thyristor.
