Control Strategy of PMSG Generator in Small Wind Turbine System
This paper presents a control strategy of turbine directly driven permanent magnet synchronous generator (PMSG) for a small wind generation system. The mathematical models of a wind turbine system, the PMSG generator and converters have been described. The control algorithms of the converter systems based on the methods of vector control have been applied. The study methodology is based on defining various study cases combining structural and operational parameters of the wind energy systems. The models of the PMSG, the force commutated rectifier, the DC bus, the buck converter and the inverter are developed and used in the control scheme. The objective of this paper is to compare between tow controls with simulation, and with more description of all the system by developing the technique needed to control the converter. The simulation results will show that the proposed control can operate with a good performance in a stand-alone wind energy conversion system for low power generation applications.
