Performance Evaluation of Dual Stator De-coupled Rotor Six-Phase Permanent Magnet Synchronous Generator for Wind Power Application

Abstract

This paper focuses on the performance evaluation of a dual stator de-coupled rotor six-phase permanent magnet synchronous generator (DSDRSP-PMSG) for wind power applications. For this application, the generator should have essential advantages like high power density, light in weight, high fault-tolerant capability and high reliability. Due to the dual stator and de-coupled rotor, the power density of proposed generator is high. The two sets of 6-phase windings also ensure their high reliability and high degree of fault tolerance capability of generator. For performance evaluation, the finite element method (FEM) is chosen because of its more accurate method of analysis. For the optimal design, magnetostatic and transient mode of analysis are considered. For the performance evaluation, transient mode of analysis is opted. The electromotive force (EMF), percentage (%) Total Harmonic Distortion (THD) and electromagnetic torque, % ripple in the torque and voltage-current characteristic are investigated for the proposed generator.
