静止无功补偿器SVC的设计与研究[摘要]功率因数偏低已成为当今电网需要解决的重要问题之一。要想提高功率因素以促进电网质量的提升，能够采取的有效方式之一就是无功补偿，而在无功补偿中静止无功补偿器(SVC)起着十分重要的作用。本文首先介绍了无功功率的产生与影响，阐述了无功补偿的作用与发展，对静止无功补偿器(SVC)、晶闸管控制电抗器（TCR）以及晶闸管投切电容器（TSC）等的结构和基本原理进行了深入分析。最后论文在simulink环境下构建了SVC的仿真模型，并进行了仿真分析。通过仿真得知，静止无功补偿器采用晶闸管控制电抗器加晶闸管投切电容器的方式，能够达到不错的无功补偿效果，使控制目标得以实现。[关键词]无功补偿；静止无功补偿器；晶闸管控制电抗器；晶闸管投切电容器。DesignandStudyofStaticVarCompensator--SVCAbstract:Lowpowerfactorhasbecomeoneoftheimportantproblemstobesolvedinpowergrid.Inordertoimprovethepowerfactortopromotethequalityofpowergrid,oneoftheeffectivewaystotakeisreactivepowercompensation,andstaticvarcompensator(SVC)playsaveryimportantroleinreactivepowercompensation.Firstly,thispaperintroducesthegenerationandinfluenceofreactivepower,expoundsthefunctionanddevelopmentofreactivepowercompensation,anddeeplyanalysesthestructureandbasicprincipleofstaticvarcompensator(SVC),thyristorcontrolledreactor(TCR)andthyristorswitchedcapacitor(TSC).Finally,thesimulationmodelofSVCisconstructedintheSimulinkenvironment,andthesimulationanalysisiscarriedout.Thesimulationresultsshowthatthestaticvarcompensatorusesthyristorcontrolreactorandthyristorswitchingcapacitor,whichcanachievegoodreactivepowercompensationeffectandachievethecontrolgoal.Keywords:reactivepowercompensation;staticvarcompensator;thyristorcontrolreactor;thyristorswitchingcapacitor.目录..........................................................................................................................................1.......................................................................................................................1................................................................................................1................................................................................................1.......................................................................................................................1....................................................................................................1....................................................................................2................................................................................................2........................................................................................3............................................................................................5............................................................................................6...........................................................................................................6..................................................................................................................6...........................................................................................6............................................................................................................6.......................................................................................................7..................................................
