Abstract
By using electromagnetic field theory and calculus of variations, the mathematic model of double-fed variable-speed constant-frequency(VSCF) wind generators was established firstly in this paper, and the two-dimensional transient electromagnetic field finite element method(FEM) was presented. To satisfy the requirement of VSCF, the electromagnetic field was coupled with the outside circuit in FEM calculation, and the stator terminal voltage was taken as the convergence condition. Rotor exciting current was iterating calculated, and the performance of double-fed wind generators at different speed and different load was analyzed. Then the obtained results were compared with the experimental data, from which it could be seen that the calculated results satisfy the engineering requirements well. All these provide some useful reference for the design and analysis of wind power generation system
