Wind Power System for Domestic Installations.

Abstract

This paper describes the simulation and testing of a low power wind system including a vernier reluctance magnet machine (VRMM), used as a direct-driven generator. The aim is to propose the design and control of the electrical part of a domestic wind power installation. We want in particular investigate the benefits and limitations due to the use of the VRMM in this system. This characteristic has led the Region to support projects concerning wind energy, notably for domestic installations of low power range (about 10 kW). The LEM tries therefore to bring improvements in this type of wind energy conversion chains, including horizontal or vertical axis turbines. Our work focuses especially on the generator and its association with AC/DC converters.We first present the structure and working equations of the VRMM and the AC/DC converters associated with it. Equations used to model VRMM and PWM rectifier in a d,q rotating frame are then detailed. A Simulink model of the system including the wind turbine is proposed. We show simulation results : we compare two methods used to drive the VRMM in order to reach the maximum power point of the turbine.

AC Losses in Form-Wound Coils of Surface Mounted Permanent Magnet Vernier Machines

“…In order to further improve the torque density and to reduce the PM material consumption, PM Vernier machines have emerged as a potential candidate [4]- [7]. One typical example is the surface mounted PM Vernier (SPM-V) machines, which have very similar structures to conventional surface mounted PM (SPM) machines.…”
