Abstract

The prime motive of the paper is to examine the design and performance optimization for a Dual Rotor Decoupled Stator Multi-Phase Hybrid Permanent Magnet Synchronous Generator (DRDCSMPH-PMSG) for wind turbine application. Such application requires the generator to be robust in nature, having higher fault tolerance capacity and high density of torque. Due to the dual rotor, the torque and the power density of proposed hybrid generator is high. The two sets of multi-phase (6-phase) winding arrangement, ensures high degree of fault tolerance capability of generator. For analysis of performance optimization of generator, the Finite Element Method (FEM) is selected, because of its greater accuracy. In order to design the generator optimally, magnetostatic and transient analyses are considered. For evaluating the performance of DRDCSMPH-PMSG, transient mode of analysis is selected. The generated EMF (electromotive force), electromagnetic torque vs time, percentage (%) THD, % torque ripple and many other characteristics are analyzed for proposed hybrid generator.
