Calculation method for equivalent circuit parameters of Doubly-Fed Induction Generator-Motor based on frozen permeability finite element analysis

This paper presents a detailed inductance model and parameters calculation method for doubly-fed induction generator-motors by using the frozen permeability method considering the influences of operating conditions. Different leakage inductance components are extracted with finite element analysis to accurately obtain equivalent circuit parameters. Finally, the traditional method, finite element method, and the proposed method are compared to verify the effectiveness of the proposed method.
