Assessing Rotor Position Impact on the PMSM Perforamance and the Dynamic Simulation with Control Position for Wind Energy Conversion

Abstract

In this paper, two parts are presented. First for the design and dimensioning of PMSM machine, we must know the distribution of the magnetic field in each part of the magnetic system and in particular at the air gap in which the energy conversion takes place. Generally, Maxwell’s partial differential equations supplemented by material’s law are used to describe the magnetic field problems. However, a numerical calculation is necessary, especially with the complex geometry of these devices. Secondly, we develop a machine Park model in relative unit to simulate a simple closed loop control imposed on the position of the PMSM rotor used in the wind energy conversion chain and this control is used to define the phase voltage have enabled to evaluate the performance of the machine.
