Modelling and control of a wind turbine equipped with a permanent magnet synchronous generator (PMSG)

This paper describes the dynamic models for a wind turbine system equipped with a permanent magnet synchronous generator (PMSG) and a back-to-back Voltage Source Converter, which is operated with the Space Vector Modulation Technique using a symmetric switching sequence. The generator side converter works as a three-phase rectifier and the grid side converter works as an inverter, which is used to interface the wind turbine system with the stand-alone hybrid system. All the components of the wind turbine system, including a typical generator side controller and except the DC-link and the grid side converter were analyzed. These dynamic models can be used for dynamic simulation in order to test different configurations, as well as control strategies and fault detection and accommodation algorithms.
