THE PROJECT SUMMARY THE PROJECT PRODUCT THE MAIN DIRECTIONS OF DEVELOPMENT Direct drive WPT with EMG. Rated wind speed at 6.5 m/s THE ESSENCE OF THE INNOVATION There are the technical decisions for WPT’s, affording efficient energy transformation of the low potential wind flow energy to the electric energy, based on the usage of EMG, allowing to regulate the electromagnetic torque on the generator’s shift in the extended range of rotation speeds, including the areas with the annual average wind speed at 3-6 m/s  Wind rotor, adapted to the low potential wind flow  The synchronous electric generator with a slotless designed stator that allows to lower starting torque at about 10 times  Electronic power converter (EPC) for adjusting the shaft torque and increasing the efficiency coefficient of EMG in the extended rotation speed range Normalized power output of WPT with EMG in comparison with analogs 4

WIND ROTOR, ADAPTED TO THE LOW-POTENTIAL WIND FLOW. CALCULATION PROCEDURE We analyzed about 100 known wind rotor profiles and performed optimization calculations for 16 options of profile We selected 2 prototypes of wind rotors – output coefficient is 0,48-0,49 at the wind speed of 4-7 m/s. We created the calculation method 6
