Brushless Doubly-fed Machine (BDFM) is a new inverter-driven induction motor, and it has broad prospects in wind power generation. This paper analyses the structure and VSCF electricity generating principle of a cascade Brushless Doubly fed Wind Power Generator, deduces the BDFG’s mathematical model, The variable structure control (VSC) was used to the active and reactive power decoupling control of the BDFM, analysis the relation of electromagnetism and energy balance .Finally, simulation and analysis of the whole system and control strategy are carried through in matlab/simulink soft. According to these results, the correct of parameters and simulation model for BDFM is proved.

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.
