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.

Doubly Fed

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.

Hardware Circuit

This paper focuses on brushless doubly-fed generator (BDFG) control system used in variable speed constant frequency (VSCF) wind power generation. For maximum wind energy capture, a direct torque control (DTC) strategy is proposed based on the relationship between the maximum absorption power and speed of BDFG. The simulation results of the control system show that the maximum power can be tracked by a quick adjustment of the torque and the feasibility of the control system is verified using Matlab. Furthermore, considering the control system platform with DSP as the core, the control system software program and hardware circuit is designed, including main program and interrupt program processes.
