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。Design and Study of Static Var Compensator--SVCElectrical Engineering and Automation Specialty REN XiaoluAbstract: Low power factor has become one of the important problems to be solved in power grid. In order to improve the power factor to promote the quality of power grid, one of the effective ways to take is reactive power compensation, and static var compensator (SVC) plays a very important role in reactive power compensation. Firstly, this paper introduces the generation and influence of reactive power, expounds the function and development of reactive power compensation, and deeply analyses the structure and basic principle of static var compensator (SVC), thyristor controlled reactor (TCR) and thyristor switched capacitor (TSC). Finally, the simulation model of SVC is constructed in the Simulink environment, and the simulation analysis is carried out. The simulation results show that the static var compensator uses thyristor control reactor and thyristor switching capacitor, which can achieve good reactive power compensation effect and achieve the control goal.Key words: reactive power compensation; static var compensator; thyristor control reactor;...
