Abstract

This invention relates to wind power. The purpose of the invention is to increase the energy production of a wind power plant by expanding the range of operating wind speeds. The confused guide casing 2 of the wind power installation, turning on support 1, is oriented in the wind. With a weak wind, the petals of the umbrella 8, installed in front of the swirler 5 flow, fully folded. Using a swirler 5, the flow twists and rotates the wind wheel 3, which in turn rotates the generator 4. With a strong wind, a small part of the energy of the generator 4 is fed to the solenoid 6, the core 7 of which opens the petals of the umbrella 8, and the petals obscure the swirl 5. On wind wheel 3 flows a stream of lower energy and it remains operable at high wind speeds. 1 il.

The invention relates to wind power engineering and relates to wind power plants that use a pre-curving air flow during operation.

The purpose of the invention is to increase energy production by expanding the range of operating wind speeds.

The drawing shows a simplified structural installation diagram.

The wind power installation contains a confusable guide casing 2 mounted on the support 1 by rotating the wind turbine 3, a kinematically connected electric generator 4 and a flow swirler 5 located at the inlet of the housing 2. The installation also contains a solenoid 6 with the core 7 and a fairing made in the form of an umbrella 8 installed in front of the swirl 5 with deviating petals kinematically connected to the core 7 of the solenoid 6 connected to the electric generator 4. For orientation to the wind The machine is equipped with a wind vane 9. The swirl 5 is made in the form of a fixed wheel with blades having sharp edges.

During operation, the vane 9 directs the body 2 to the wind, turning it on support 1. If the wind speed is lower than the nominal, then the petals of the umbrella 8 are folded, the blades of the vortex 5 are open and wind up the flow that runs onto the wind wheel 3. As a result, the wind wheel 3 spins the rotor of the electric generator 4, which generates electricity at low wind speeds. With increasing wind speed and power

electric generator 4 is a small part of the energy generated by it enters the solenoid 6, displacing the core 7, which opens the petals of the umbrella 8. As the wind speed increases, the petals of the umbrella 8 increasingly overlap the blades of the whirlwind 5, which turns the flow less and less, and the electric generator 4 at the same time, it provides the consumer with electricity of constant nominal power. At the maximum wind speed, the petals of the umbrella 8 completely obscure the swirler 5 and the wind wheel 3 operates from a non-swirling flow of relatively low power, which allows increasing the value of the maximum operating wind speed.

Claims (1)

Invention Formula A wind power installation containing a confusable guide casing mounted on a support, a wind wheel housed in it, a kinematically connected electric generator and a swirler located at the casing inlet, differ from one another to the fact that in order to increase power generation by expanding the range of operating wind speeds, the installation additionally contains a solenoid with a core and a fairing made in the form of an umbrella installed in front of the swirler with deflectors, kinematically connected with the core of the solenoid connected to the generator.
