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.
