Optimization of a wind turbine using permanent magnet synchronous generator (PMSG)

Abstract

This paper proposes strategies for a Wind Turbine with a Voltage Source Converter (VSC) in the case of a 200-300kW Permanent Magnet Synchronous Generator (PMSG). This control allows the synchronous generator to operate at an optimal speed. To show its effectiveness, a mathematical model of a variable speed wind energy conversion system is developed. The mathematical model is used to calculate the response of the wind energy conversion and to determine the maximum power operating point. This paper also provides the theoretical background of this method. Simulation of the system using Matlab / Simulink / SimPower System was performed to illustrate the advantages of this control strategy.
