| 摘 要： | 利用小信号分析法 ,对可控串补的频率响应特性进行了研究。对可控串补输入小信号电流 ,求取可控串补中各电压电流 ,并利用傅里叶分析方法求得各信号的相应频率分量 ,进而求得可控串补的频率响应特性。该研究对可控串补系统的次同步谐振以及其他相关的谐波研究有重要意义 ,分析方法对其他FACTS元件的研究有借鉴作用。EMTP仿真验证了本文方法的有效性。

| Abstract: | Small signal method is used to derive the frequency response of a thyristor controlled series capacitor(TCSC) A small signal current is imported into TCSC,then the voltages and currents of TCSC and their spectral analysis are presented,at last the frequency responses of TCSC are obtained The study is important for sub synchronous resonance(SSR)as well as other harmonics related and the method could be applied to the analysis of other flexible alternating current transmission system(FACTS)devices Electric magnetic transient program(EMTP)simulation also be used to verified the validity of the method |
