双馈风机特征值分析的建模与模态分析
摘要:为研究双馈风机次同步现象，以特征值分析法为基础，研究双馈风机单机无穷大系统。在Simulink平台搭建其动态模型，编程求取系统运行初值、模态特征值和参与因子；进一步对系统进行模态分析，识别出机电模态、轴系模态和次/超同步模态，尤其次同步模态，验证了系统参数变化对于双馈风机次同步影响的一般性结论。

Abstract：To study the sub-synchronous phenomenon of doubly fed induction generator (DFIG), based on the eigenvalues analysis method, this paper studied the single machine infinite bus system of DFIG, built the dynamic model on Simulink platform and obtained the initial value of system, modal eigenvalues and participation factors. The modal analysis of the system was further carried out, including electromechanical mode, shaft mode and sub-synchronous resonance (SSR)/sup-synchronous resonance (SupSR) mode, in which the SSR mode verified the general conclusion of the influence of system parameters on the sub-synchronous of DFIG.
