| 摘 要： | 正确分析TCSC次同步频率阻抗特性是研究TCSC抑制次同步谐振（SSR）能力以及进行TCSC参数设计的重要基础。基于对TCSC次同步频率阻抗模型的研究，绘制了三维频率阻抗图，分析了TCSC次同步频率阻抗特性，特别提出了次同步谐振导通角的概念。基于内蒙古上都电厂串补输电线路模型，在满足工频基波阻抗调节特性的前提下，根据次同步频率阻抗特性研究了考虑TCSC自然抑制SSR时其主电路参数的设计原则。通过对上述系统各模态频率阻抗特性的综合分析，讨论了TCSC控制参数的选择方法。仿真结果证实了次同步频率阻抗特性分析结果的正确性。

| Abstract: | The correct analysis of subsynchronous frequency impedance characteristics of Thyristor Controlled Series Capacitor (TCSC) is acknowledged as being essential to evaluate the ability for mitigating subsynchronous resonance (SSR) and to select parameters for TCSC. In this paper, a three-dimensional diagram of subsynchronous frequency impedance characteristics is obtained based on the research of the subsynchronous frequency impedance model. And this paper analyzes subsynchronous frequency impedance characteri... |
