利用特征值分析法的双馈风电机组模型降阶
Simplification of DFIG Models with Eigenvalue Analysis
摘要
Abstract
The construction of doubly fed induction generator(DFIG)which is suitable for the simulation of power sys-tem is of significance for the integration of wind powers. In this paper,a simplification method of a DFIG model and its verification are studied by means of eigenvalue analysis. Based on a detailed model of DFIG,the modules including wind turbine,generator stator and rotor,as well as converter,are simplified,and a DFIG model which is suitable for the electromechanical transient simulation of power system is constructed. Analysis results indicate that the adopted sim-plified method can reflect the main dynamic characteristics of DFIG model. Simulations in time domain and error analy-sis also indicate that the simplified model can reflect the response of DFIG to disturbances through the stability analysis of power system,which verifies the correctness and validity of the proposed simplified method.关键词
