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.

SUBSTANCE: method to increase the capacity level produced by a turbine for fluid medium comprises support of the turbine for fluid medium, containing a bandage 102 of a turbines with aerodynamic contour, having an inlet, an outlet and a ring 118 made of the mixing protrusions 120a, located along the trailing edge, cascade 104 of a turbine installed in the turbine bandage 102 and the ejector shroud, located further downstream of the turbine bandage 102 and having an inlet and an outlet, reception area and the primary air flow into the inlet of turbine bandage 102, initiating rotation of cascade 104 of the turbine by the primary air stream, which transmits power of cascade 104 of the turbine, and mixes the primary air flow with lesser energy with the secondary air stream with higher energy, that bypassed bandage 102 of a turbine.

EFFECT: provision of rapid mixture of the flow leaving the turbine, having low energy, with a bypass air flow, having more energy, before leaving the system.

FIELD: power engineering.

SUBSTANCE: air flow power plant comprises an air channel and shells. In the air channel there is a generator with an impeller. The shells are filled with gas lighter with air, for instance, helium. The air channel is made in the form of a rope structure and is coated with an air impermeable fabric. The rope structure comprises circular belts at a certain distance from each other and is supported with shells fixed to the upper part of the structure and at a certain distance from each other along the height to appropriate belts. Shells by means of valves and pipelines are connected to a pump station comprising reservoirs for gas lighter than air, for instance, helium. At the specified distance from the surface of earth or water there is a rope system fixed to appropriate belts. The rope system is fixed also to shells or to levers fixed also to the earth surface by means of blocks, or is attached to floats fixed to anchors, which may be attached to the bottom or stay in the water thickness. A film transparent for solar radiation is attached to the rope system. Water surface or dry land may also be coated with a film.

EFFECT: simplified manufacturing, increased reliability and efficiency of a power plant.

SUBSTANCE: turbine plant comprises a blading 11, which includes curved blades, an inner end of each one is closed in a cavity 14, open at one side; and a generator 20, arranged in the cavity 14 and connected with the blading 11. Each curved blade has a dynamic structure and is made as capable of increase in size under action of hydrostatic pressure and with the capability of compression under action of counterpressure.

EFFECT: simplified design and efficient operation.
