WIND WHEEL AND WIND-DRIVEN POWER PLANT ON ITS BASIS Russian patent published in 2012 - IPC F03D1/02 F03D7/04 F03D11/04 

FIELD: power industry.

SUBSTANCE: wind wheel includes at least three wind blade wheels installed on a common shaft. Each wind wheel represents turning blades fixed on the bushing. Bushing of one of the wheels is rigidly fixed on the shaft. Bushings of the rest wheels are moving along longitudinal axis of the shaft. Wind wheel the bushing of which is rigidly fixed on the shaft is the main wheel, and two other wheels which are located on both sides of the main wheel are moving ones. Fastening of blades of each wheel, when all bushings are connected, provides the location of wind wheel blades in one plane so that equal angles are formed between them. Moving bushings are provided with possibility of fixing their position. Wind-driven power plant includes at least three detachable modules, wind metre and control unit. Detachable modules are fixed on metal frame installed on rotating platform. Control unit is connected to wind metre and rotating platform. Each detachable module includes wind wheel connected to the control unit and in-series connected to multiplying gear, electric generator and frequency converter. Detachable modules are fixed on metal frame so that parallel location of rotation axes of all wind wheels is provided.

EFFECT: increasing energy output, efficiency of wind use in wide range of wind loads; improving reliability and repairability of wind-driven power plant.
