With increasing emphasis on the energy crisis and environmental pollutions, wind power has been developing rapidly worldwide. Because of its unique advantage of variable-speed constant-frequency (VSCF), doubly fed induction wind generator (DFIG) has been widely used in the wind power industry. In this paper, a 3.5kW doubly fed induction wind generator is designed and modeled utilizing ANSOFT, after the optimization of the generator parameters, the data of the stator and rotor no-load and full-load are given by simulation. On this basis, a physical model of doubly fed wind generator is established by Maxwell 2D. And through a finite element triangulation, the distributions of magnetic lines of force and magnetic field within the motor are obtained.

The brushless doubly-fed machine (BDFM) is a new type of induction machine with good application in wind power generation. In this paper, the design method for the stator winding and rotor winding of BDFM in detail on the basis of operation principle of the machine is introduced. As an example, The performance simulation for a 480kW cage rotor BDFM with 8-pole stator power winding and 4-pole control winding can be considered under the condition of no-load, rated load and variable speed constant frequency operation based on field-circuit coupled finite element analysis. Simulation results show that the design method has good performance and is feasible in variable speed constant frequency wind generation systems.
