摘要：The aim through this paper is to control the power of the wind turbine in strong winds,consequently the protection of the wind generator system. The latter is composed of a threebladedturbine, a mechanism of mechanical orientation of blades, and a double-fed inductiongenerator (DFIG), controlled by the variation of quantities rotor , the rotor part is connected tothe infinite network of 690 Volts 50 Hertz through a cascade (rectifier, filter, inverter). Ourcontribution is to present a control method applied to a wind generator connected to the gridand in the case of strong winds. The magnitudes are controlled by a field oriented control(FOC).. For wind speeds of which the wind power is lower than the acceptable one, we get theoptimal partial power back while applying the MPPT algorithm. For wind speeds of which thedeveloped power exceeds the acceptable standard of that nominal, we limit the power producedby action of the mechanical system which makes revolve the blades of a necessary mechanicalangle to limit the rotation speed of the turbine, corresponding to the power of instruction.Simulation results under Matlab/simulink are presented.
