Model and Simulation of a Wind Turbine and its Associated Permanent Magnet Synchronous Generator

Abstract In this paper, a modeling and simulation of the assemble of a wind turbine and a synchronous generator with permanent magnet operating are presented. In a first step, we present the result of simulation under Matlab / Simulink software of the wind turbine of the power coefficient Cp as a function of the orientation strategy of the blades. This strategy is important as it allows the wind turbine to operate autonomously according to the wind speed giving rise to variable maximum powers. In a second step, the permanent magnet synchronous generator (PMSG) is specifically modeled. In this approach, we recall the need to change the reference (abc) in order to simplify the equations and thus allow the realization of orders. Finally, the voltages of the idle operation of such a generator are simulated in real marks abc and that of Park dq, respectively. Thus the obtained results analyze, even optimize the behavior of the two main components allowing the conversion of the wind energy in electric energy, i.e. the wind turbine and the synchronous generator, of a medium power wind production chain.
