WIND-DRIVEN POWER PLANT WITH MULTISTAGE ROTOR Russian patent published in 2013 - IPC F03D1/02 F03D9/00 

FIELD: power engineering.

SUBSTANCE: wind-driven power plant comprises a rotor, an intermediate reducer, a hydraulic system, a hydraulic pump, a hydraulic motor, a regulator of hydraulic motor rpm and an electric energy generator. The rotor is broken into independent stages according to the diameter, installed on coaxial shafts. The plant is equipped with an intermediate shaft that provides for transfer of torque to the shaft of hydraulic pumps, a sensor of second flow rate of liquid and a hydraulic adapter. Coaxial shafts are communicated by means of the intermediate reducer and free wheel couplings with the intermediate shaft. The total capacity of the plant is broken into separate energy blocks. The torque from each stage is sent via telescopic shafts, free wheel couplings, the intermediate reducer to the shaft of hydraulic pumps. Hydraulic motors rotate the generator rotor with continuous rotations regardless of the wind speed, since they have controllers of permanent rotations. Couplings provide for independence of stages operation relative to each other. Therefore, each stage of the rotor rotates with a different angular speed. Summation of torques of stages is carried out with an intermediate reducer.

EFFECT: higher coefficient of wind energy usage due to rotor breakdown into stages with the same diameter of the rotor.
