THE MAIN DIRECTIONS OF DEVELOPMENT

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

THE PROJECT SUMMARY

THE PROJECT PRODUCTDirect drive WPT with EMG.

Rated wind speed at 6.5 m/s

THE ESSENCE OF THE INNOVATIONThere 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

Normalized power output of WPT with EMG

in comparison with analogs

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

WIND ROTOR, ADAPTED TO THE LOW-POTENTIAL WIND FLOW. TEST

The flow speed at 4 m/s, 10 rad/s

The flow speed at 6 m/s, 14 rad/s

The flow speed at 8 m/s, 18 rad/s

Tests of the wind rotor prototype with diameter of 0.8 m on the aerodynamic stand

Producing the prototype of WPT with EMG of 2 kW capacity.

Conducting full-scale tests of WPT with EMG according IEC 61400-12-1: 2005, certified experts DNV GL

(http://www.dnvgl.com/about-dnvgl/default.aspx).

The development of the commercial version of the Product with power output from 0.5 to 30 kW.

Development of design documentation of pilot production and technology pilot production.

Attraction of the investments

THE RESULTS OF STAGE 1 OF THE PROJECT (APRIL-DECEMBER 2015)

We designed, created and tested:

•The prototype of the electronic machine generator with an electronic power converter

• The wind rotor prototype with diameter of 0.8 m.

We created bench for simulating the operation of the wind turbine based on the test bench for electrical

motors (certificate № 432-3582-15 "TEST-S.-Petersburg").

We designed a WPT with EMG, with rated wind speed at 6.5 m/s.

We also created a test field for wind monitoring and full-scale testing of WPT with EMG.

We file an international application PCT/RU2015/000918 from 12.23.2015, the patent for the invention
