| 摘 要： | 本文提出了考虑时滞影响的静止无功补偿器(SVC)广域附加阻尼控制器的设计方法。以含有SVC的新英格兰电力系统为例,通过几何可控/可观度分析选择SVC的附加阻尼控制器的广域输入信号,采用留数法计算得出了其时滞补偿参数,随后采用时滞稳定性判据分析了含有SVC常规附加阻尼控制器的增益与闭环电力系统的时滞稳定裕度的关系,最后根据时滞稳定裕度结果确定了SVC附加阻尼控制器的增益。仿真结果表明,考虑时滞影响的SVC附加阻尼控制器既能够提高系统的阻尼特性,又具有一定的时滞鲁棒性。

| Abstract: | The conventional wide-area supplementary damping controller(WSDC) of static Var compensator(SVC) has been investigated.The New England test power system(NETPS) equipped with a SVC is used as the test system.At first,the input wide-area signal of the WSDC is selected by analyzing the controllability/observability of linear model of the NETPS.Then,the residue method is used to determine the parameters of the conventional WSDC.The delay-dependent stability of the closed-loop power system is analyzed.The gain of the conventional WSDC is determined by using the analysis results.Simulation results are presented to show that the designed conventional WSDC of the SVC can improve the damping performances and handle a relative large communication delays. |
