Design and Simulation Analysis of Doubly Fed Induction Generator Wind Turbines
Abstract:
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.
