Design and Analysis of a Novel Type of Double Stator Switched Reluctance Wind Turbine Generator

Conventional switched reluctance wind turbine has the problem of low energy density and big torque pulsation, in order to solve this problem, a new type of dual-stator switched reluctance generator motor is designed and its working principle is introduced. The new dual-stator switched reluctance generator is divided into dual structures of inside stator and outside stator, and both of them adopt the U-shaped stator structure. Changing the polarity assignments of the magnetic fields of the inside and outside stator and optimizing positions of the excitation phases at the same time can uncouple the magnetic fields of the inside and outside stator and improve the flexibility of the control of the new generator. Through the finite element static and dynamic simulation of the machine, the magnetic flux, torque, voltage, and current characteristics are analyzed. Then the prototype and test platform are built, and the rationality of the structural design and the validity of the simulation analysis are verified by experiment.
