Power Losses Calculation in Wind Power Plant based on a Vector-Controlled Permanent Magnet Synchronous Generator

Mathematical model of a wind turbine is investigated, which includes mathematical descriptions of a horizontal axis small- scale power wind turbine with permanent magnet synchronous generator with vector control and a three-phase rectifier connected to a stand-alone voltage source inverter. The maximum power point tracking of the wind turbine, which calculates the optimal rotation turbine speed for each wind speed is used. Vector control system provides the calculated optimal rotation turbine speed. The mechanical losses in the gearbox and in the synchronous machine are determined, as the iron losses and copper losses in the permanent magnet synchronous machine and commutation losses (switching and conduction losses) in stand- alone voltage source inverter are taken into account.
