摘要
基于模块化建模的方法,考虑实际电路结构,建立了含H桥级联型静止同步串联补偿器(SSSC)的系统小信号模型。结合实际工程参数,通过对比小信号模型计算结果与PSCAD/EMTDC电磁仿真结果,验证了小信号模型的准确性。然后采用特征值分析法分析了该系统的振荡模态,并研究了控制器参数对系统小干扰稳定性的影响。研究结果表明随着解耦控制器以及均压控制器参数的增大,系统稳定性均增强。最后通过时域仿真算例验证了特征值分析结论的准确性。
Based on the modular modeling method and considering the actual circuit structure,the small signal model of the system with H-bridge cascaded SSSC(Static Synchronous Series Compensator) is established. Based on the actual engineering parameters,the accuracy of the small signal model is verified by comparing the calculative results of the small signal model with the PSCAD/EMTDC electromagnetic simulative results. Then the eigenvalue analysis method is used to analyze the system oscillation mode,and the influence of controller parameters on the system stability under small disturbance is studied. The study results show that the system stability is enhanced with the increase of the parameters of the decoupling controller and the equalization controller. Time domain simulation verifies the accuracy of eigenvalue analytical conclusions.
