A prototype of the electrical part of a variable speed wind turbine is considered, equipped with a permanent-magnet synchronous generator. The modelling of the generator and power electronics interface is checked with measurements realized in the prototype, under both steady-state and dynamic conditions. Measurements and control functions are performed by using a microprocessor. The outcome of the simulation and experimental work are actually utilized in the development of a 25 kW wind turbine, in the frame of a research project.

This paper proposes an optimized model and control strategy for variable speed wind turbine using permanent magnet synchronous generator (PMSG). Models and equations that describe different components of the wind energy conversion system (WECS) are addressed and their implementations into PSCAD/EMTDC are described. There are different types of synchronous generators, but the PMSG is chosen. It offers better performance due to higher efficiency and less maintenance since it does not need external DC source and can be used without a gearbox, which also implies a reduction of the weight of the nacelle and a reduction of costs. For the better performance, in this model two level IGBT converter and three level IGBT inverter set has been used associated with the maximum power point tracking (MPPT) system.Simulation results show that the controllers can extract maximum power and regulate the voltage and frequency under varying wind and load conditions. The controller shows very good dynamic, steady state and transient performance.

In this article, we process the modeling and control of a global chain of the wind energy conversion system based on a permanent magnet synchronous generator, and the injection of the produced energy into electrical grid. The proposed control technique of the wind energy system is based on a sliding mode control which is designed for a variable speed wind turbine. Sliding mode control is assessed on a wind turbine to supply three phases grid. The aim in this work is to operate over all the wind conversion system at its maximum power point. Initially, three controls have been designed by sliding mode control: the first is for electromagnetic torque of the used permanent magnet synchronous generator, the second is for the machine side converter, and the last is for the grid side converter. Thereafter, another proportional integral controller has been designed for the phase looked loop. Finally, the permanent magnet synchronous generator–based wind turbine and the grid are modeled, and proposed controls are applied, various simulations results by MATLAB/SIMULINK environment are presented and discussed.
