WIND POWER PLANT WITH DAM Russian patent published in 2014 - IPC F03D1/02 F03D11/04 

FIELD: power industry.

SUBSTANCE: wind power plant comprises air flow concentrator, wind wheels, power generators, air supply control system to wind wheel blades and protection system against hurricane winds. Concentrator is formed by dam walls installed in the sit of mountain gorge at its outlet to the valley and by gorge surfaces. Dam is directed towards the gorge by its broad part. Wind wheels on shafts of electric generators of horizontal design are installed in its narrow central part in the round openings. Shut-off dampers of air supply control system are installed from inner side at inlet of round openings, and protective flaps in the form of sliding gates are located from inner side of all central part of the dam. Wind wheels can be made of blades of aircraft type, shut-off dampers of air supply control system can be of diaphragm type. Protective flaps in operation mode are located in niches of the dam walls. Central part of the dam can be made with angle directed from the gorge. Stiffening ribs are made from exterior part of the dam and intercostal space is filled with rocky soil, which is secured against ravelling by horizontal meshy stripes fixed on the dam and stiffening ribs.

EFFECT: efficiency upgrading of air flow energy conversion at different wind speeds by using surfaces of gorge and protection system against hurricane winds.
