针对目前由串补电容引起的次同步振荡问题日益严重的现象，文章拟利用TCR型SVC抑制次同步振荡。通过对次同步振荡与SVC的原理的研究，文章用MATLAB／SIMULINK建立了TCR型SVC仿真模型，并采用IEEE 第一标准的模型来验证文章建立的模型的有效性。通过次同步振荡研究的时域仿真技术得出第一标准模型在安装SVC 时，次同步振荡现象明显小于不安装SVC时。文章进一步对不同类型SVC在抑制次同步振荡的特点进行对比分析，对TCR型SVC进行优化，得出了改进后的SVC对次同步振荡抑制的效果会进一步提高的结论。

According to the present serious phenomenon of series capacitor compensation inducing sub -synchronous oscillations, this paper proposed to use TCR SVC to suppress the sub-synchronous oscillations .Based on the research of the sub-synchronous oscillations and SVC theories , this paper used MATLAB/SIMULINK to establish TCR SVC simulation models .The effectiveness of models was tested by the IEEE first standard model of researching sub-syn-chronous oscillations .MATLAB was used to do domain simulation of this model which was with and without SVC . Comparing the different types of SVC′s features on suppressing the sub-synchronous oscillations , this paper improves the SVC based on the comparison .The conclusion can be got that the improved SVC has a better effect on suppressing the sub-synchronous oscillations .
