Making full use of wind energy was the main objects in the control of wind power generation. The maximum power point tracking control for wind power generating system using switched reluctance generator was studied. A model of six phase 12/10 switched reluctance generator wind power generating system was presented. A constant resistance controlled circuit was set between switched reluctance generator and converter. The maximum power point tracking (MPPT)algorithm was elaborated. Thanks to the constant resistance control circuit, the MPPT algorithm was realized easily. MPPT algorithm was realized without speed sensors. The tests proved that the proposed system extracted maximum wind energy.
