HELIOWIND POWER PLANT OF INCREASED POWER Russian patent published in 2020 - IPC F03D3/04 F03D3/06 F03D7/04 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of renewable energy sources, namely, to conversion of solar and kinetic energy of wind into electric energy, for powering loads of end user, and can be used in equipment of alternative power systems and creation of autonomous complex of several units, combined into wind power stations. High-power helio-wind power plant includes a bladed turbine with a vertical axis of rotation, which is located inside the wind-guiding device with the lower and upper covers. Electric generator is located on the axis of the blade wind turbine. Photoelectric converter of light energy is installed on the upper cover. Vane turbine is made in the form of parallel disks, fixed by axial holes with rotary shaft, forming hollow drums. Vertical blades are arranged between discs inner surfaces. Turbine is located in the wind-guiding device center, made in the form of uniformly distributed in circumferential direction vertical spiral wind-screening screens, made in combination with blades of wind turbine in the form of unwinding spirals, which beginnings are fixed on vertical rotary shaft, and ends are directed to periphery of wind-guiding device. Wind control panels top edges are connected with upper cover, lower edges are connected with bottom cover to form nozzle air chambers. Cutoff plates are built into the body of wind-guiding shields. In addition, reversible drives and cutoff plate opening angle pickups, electric generator stator windings speed and temperature sensor, air flow pressure sensors and control device are introduced. Ends of cutoff plates are located closer to rotation axis of rotor and are connected to rotary shafts of cutoff plates, made with possibility of limited turn of cutoff plates around vertical axis. Rotary shafts of cutoff plates are mechanically connected with reversing drives and sensors of opening angles of cutoff plates. Vertical rotary shaft is connected with rotation speed sensor. Outputs of cutoff plates opening angle sensors, air flow pressure sensors, rotation speed sensor and electric generator stator windings temperature sensor are connected to inputs of control device, and outputs of control device are connected to inputs of reversing drives of cutoff plates.

EFFECT: technical result, for achievement of which the invention is aimed, consists in improvement of reliability of power supply to consumers in a wide range of wind flow rates and providing effective independent operation irrespective of direction of wind flow with high efficiency factor; significant reduction of level of mechanical and aerodynamic noise is achieved simultaneously.
