Optimization of Multi-pole Three Phase Permanent Magnet Synchronous Generator for low speed Vertical Axis Wind Turbine

This paper focuses on developing an optimal system of Vertical Axis Wind Turbine (VAWT) for low wind speed. After studying the performance analysis of the turbine parameters for speeds less than 5 m/s, a realistic model was designed in Matlab/SimulinIc that could produce suitable torque for low wind condition. The Multi-pole Axial Flux Permanent Magnet Synchronous Generator (PMSG) had been proven to be a good choice for this optimal design as it performed well enough to generate sufficient amount of voltage and power. The turbine design parameters such as the radius, height and wind speed were varied to observe the change in generator output voltage and power and based on that an optimal design for Permanent Magnet Synchronous Generator was proposed in this paper. The simulation results were tested with an actual Permanent Magnet Synchronous Generator in laboratory applying the optimized turbine parameters and were compared accordingly for error calculation. Lastly, future possibility of improvement and the limitations had been proposed to develop the system further.
