中文摘要

电力变换器系统的暂态稳定性备受关注。由于多级级联控制环路的存在,变换器系统表现出高阶非线性动力学特性,这成为暂态稳定性分析的难点。本文考虑了虚拟同步机(VSG)有功与无功控制环路之间的动态耦合,对并网VSG系统的暂态稳定性进行了深入分析。

English Abstract

Transient stability issues of power converter systems have attracted much attention. Generally, the converter systems behave in high-order nonlinear dynamics due to multiple cascaded control loops, which become obstacles for transient stability analysis. Considering the dynamic coupling between active power and reactive power control loops, the grid-tied virtual synchronous generators (VSG) system...
