Dynamic Performance Analysis

In this paper, the study and optimization design of stator coreless axial flux permanent magnet synchronous generators is presented for direct driven variable speed renewable energy generation system applications while considering the requirement of reliability and dynamic performance with unstable input conditions. The dynamic analytical model is developed based on the investigation of the axial flux permanent magnet synchronous generator (AFPMSG) structure and basic electromagnetic equations to find out the relationship between generator parameters and dynamic performance. Simulation via the MATLAB/Simulink platform is carried out to obtain the sensitivity of dynamic performance to generator parameters. An integrated optimization model that takes the key parameters as variables is proposed, aiming to improve the mechanical dynamic performance of AFPMSG. For accurate design, the design procedure is modified by combining the nonlinear iterative genetic algorithm (GA) to perform the calculation. A 3_kW AFPMSG is optimally designed to minimize the output voltage overshooting—the index of dynamic performance for direct driven variable speed generation application. Finally, a three-dimensional (3D) finite element model of the generator is established by Maxwell ANSOFT, and the simulation results confirm the validity of the dynamic performance analysis and optimal design procedure.

Permanent Magnet Synchronous Generator

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/ Simulink 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.
