Modeling of VAWT-AFPMSG using the finite element method for wind energy conversion

Abstract

In the context of the global energy transition and decarbonization efforts, wind energy has become a crucial component of sustainable power generation. Among the various electrical generators utilized, the Axial Flux Permanent Magnet Synchronous Generator has garnered considerable attention due to its significant advantages in wind energy conversion. Its axial configuration is particularly advantageous for applications where space and weight are critical factors. This article presents a detailed modeling and simulation of a vertical axis wind turbine system based on the Axial Flux Permanent Magnet Synchronous Generator. The design process began with the development of a 3D electromagnetic model in ANSYS Maxwell through RMxprt model, where both geometric and magnetic characteristics were defined. In parallel, MATLAB/Simulink was employed to model the wind turbine and implement a Maximum Power Point Tracking algorithm to maximize energy capture and field-oriented control. A cosimulation in Twin Builder integrating Maxwell and Simulink was developed to ensure realistic performance evaluation, enabling dynamic interaction between mechanical and electrical subsystems. This approach provided an effective platform for evaluating system performance in conjunction with the electromagnetic modeling of power electronic circuits.
