| 摘 要： | 分析了由静止同步串联补偿器(SSSC)与固定串联电容器(FSC)组成的混合串联补偿装置(HSC)的原理,研究了HSC安装位置和补偿容量配比对发电机电气阻尼特性的影响。结果表明,在不采用主动阻尼控制时,HSC自身能够缓解但不能从根本上解决次同步谐振(SSR)问题。提出了SSSC主动阻尼SSR的控制机理,即通过对SSSC的电压参考值(电抗参考值)进行次同步频率调制,控制其输出电压的幅值和相位使其在系统中产生大小和相位适当的模态互补频率电流,进而在发电机中产生对应模态的阻尼扭矩,实现主动阻尼SSR的目的。设计了主动阻尼控制器,提出了其参数整定方法。复转矩系数法和时域仿真法结果表明,采用主动阻尼控制后,HSC能够有效地抑制SSR。

| Abstract: | This paper analyzes the principle of hybrid series compensator(HSC),which is composed by static synchronous series compensator(SSSC) and fixed series capacitor(FSC).The impact of installation location and compensation ratio of HSC on electrical damping is studied.Results show HSC can weaken but can't damp out the SSR problems without active damping.The principle of SSSC to actively damp sub-synchronous resonance(SSR) is proposed,which is realized by modulating the voltage(reactance) reference value of SSSC ... |
