同步调相机次/超同步阻抗建模方法与特性分析
Modeling Method and Analysis of Sub/Super-synchronous Impedances of Synchronous Condensers
摘要
Abstract
The configuration of synchronous condensers is currently a commonly used measure to enhance the oscillatory stability of renewable energy integration systems.However,there is limited research on the mechanism of frequency-coupled impedance in synchronous condensers.Discrete numerical solutions for the frequency-coupled impedance of synchronous condensers can only be obtained through frequency-sweep measurements or programmatic calculations.The internal mechanism of the condenser impedance model remains unclear,posing numerous limitations to studies on sub/super-synchronous oscillation suppression in power grids using impedance analysis methods.To address this,this paper proposed an analytical method for the impedance of synchronous condensers.Based on the analytical results,the study analyzed the decisive parameters affecting the external impedance characteristics at the mechanistic level,providing research insights for the oscillatory stability analysis of regional power grids with synchronous condensers and additional damping control methods.关键词
