A wind power system, having at least one rotor, which controls a respective driven utility apparatus, and at least one stator. The rotor includes vanes arranged radially, which have a substantially flat profile. The vanes are inclined with respect to the rotation axis of the rotor through an angle between 25° -90°. The system further includes at least one stator arranged upstream of the rotor and is provided with a tubular body coaxial to both the shaft of the rotor and a substantially cylindrical outer enclosure. The tubular body includes a tapered end and curved blades profiled to direct the air entering the system toward the outerportion of the rotor onto the vanes. Between the inner walls of the enclosure, two adjacent blades, and tubular body, there is a forced path for the air entering the system.
