摘要
随着输电电压的升高、输电距离的增长,电力系统中安装的串联型柔性交流输电(Flexible AC Transmission,FACTS)装置日渐增多,如何抑制多个串联型FACTS元件间的交互影响并保证其协调运行就变得尤为重要。文章运用奇异值分解法(SVD)理论计算分析了多个串补元件同时投入运行时元件之间存在的交互影响,并利用PSCAD搭建仿真模型,进行了仿真验证。仿真结果表明,元件间交互影响造成的电压波动和传输功率不稳定对系统产生了不利的影响,并利用matlab进行傅立叶变换对稳定后的母线电压进行了谐波分析。
In recent years, with the increase of transmission voltage and transmission distance, series-type FACTS de- vices installed in the power system are increasing, the problem of how to inhibit the interaction between multiple com- ponents and ensure their coordinated operation will become particularly important. This paper uses singular value de- composition （SVD） to theoretically analyse the interaction between multiple series compensation elements. And this paper focuses on using the simulation software PSCAD to build up model and carry out the simulation verification. According to the simulation results,the impacts of the interaction between components, voltage fluctuations and trans- mission power instability affect power system adversely and using matlab to carry out harmonic analysis for the stable bus voltage.
