The growing interest in wind turbine applications and the fast development of power electronics is making the manufacturers to find the most suitable and low cost technologies to put in practice. Permanent magnet synchronous generator are becoming more popular over the induction machine in wind turbine applications, because of the increased power to volume ratio, decreasing cost of magnets, and increased efficiency.
In this scope, the purpose of this project is to find a solution in order not to use the sensor mounted on the shaft of the surface mounted PM for wind turbine applications. The control strategy used is Field Oriented Control(FOC). First FOC is implemented and validated in Matlab/Simulink using measured speed and position. Next, the investigation on methods to estimated the rotor position is done. With the chosen method the validation of the control is performed. The sensored Field Oriented Control is implemented in dSpace laboratory and the results have proved that the control is working properly. The sensorless algorithm is working in simulations and could not be implemented in laboratory.
