| 摘 要： | 数学模型的研究对于装置性能的研究、主电路参数设计和控制系统设计具有重要意义。该文通过傅立叶分解的方法，建立了链式STATCOM的数学模型。该模型正确反映了暂态过程中，基波电流有功分量、基波电流无功分量和电容电压平均值的变化规律。基于PSCAD的仿真验证了模型的正确性。该文还基于该模型讨论了链式STATCOM开环响应时间常数与主电路参数之间的关系。

| Abstract: | Cascade STATCOM (Static Synchronous Compensator) has been widely studied because of its advan-tages over traditional STATCOM configurations. However, for deep research on cascade STATCOM, such as main circuit configurations, transient performance analysis, and control system design, a mathematical model is extremely needed. In this paper, by using a method of Fourier decomposition, a mathematical model describing dynamic characteristics of cascade STATCOM devices is presented. Based on it, the relationship between open-loop response time constant and the main circuit parameters of cascade STATCOM are analyzed. The proposed model is verified by digital simulations. |
