Description

The invention relates to energy and is intended to convert solar and wind energy into electrical energy.

A solar-wind power plant (SVEU) is proposed, based on the joint use of solar energy and wind energy, which guarantees reliable accumulation of energy in the accumulator and its subsequent use to drive the power supply generator of stabilized frequency and voltage. It is proposed to power the buffer use of energy, made by a dual-circuit.

The design of the SVEU is suitable for high-power power installations, the SVEU meets the requirements of ecology and is a promising alternative to traditional energy sources that pollute nature and are in a depletion stage.

The nearest known solar-wind installation is an installation containing receivers of solar and wind energy, a storage device and a generator.

The disadvantages of solar-wind power options are: solar-wind energy receivers are connected in parallel to the energy store directly, and not through a converter; lack of compressors; The gas turbine generator of the solar-wind power plant is connected directly to the electrolyzer.

In addition, the known NEEDs are devoid of an important quality — the saving of water undergoing electrolysis.

The purpose of the invention is to increase efficiency.

The drawing shows the NEED.

In order to eliminate the noted deficiencies, increase efficiency in the design of the proposed SVEU, compressors electrically connected to the converter were introduced in front of the receivers, and a pump connected to the generator and electrically connected to the generator was installed on the condensate line after the engine.

SVEU consists of solar energy receivers (solar batteries) 1 and wind energy - wind turbine 2 with a generator, the outputs of which through converter 3 are connected to an energy storage unit - electrolyzer 4 connected to pipelines with hydrogen and oxygen pumping compressors 6, and compressors 5 and 6 connected by pipeline with receivers 7 and 8, the outlets connected to engine 9,

connected to the power supply generator 10 through the gearbox. The engine 9 is connected by pipeline with the electrolyzer 4 through the pump 11 pumping water, and the pump

5 11 pumping water is electrically connected to the generator TO. The pump 11 is turned on automatically as water - condensate accumulates.

The SVEU used a rotary wind turbine that automatically reached the optimal mode due to the kinematic connection of the rotors with a swivel head.

NEED works in the following sequence:

5 In the presence of any kind of energy - the energy of solar rays or wind energy, or their joint effect, the voltage from the wind turbine generator and solar panels goes to the converter

0 3, which performs the function of converting currents or voltages with interlock sources, and then into the electrolyzer 4, filled with water with a small amount of caustic soda (weak water capacity).

Receivers of solar and wind energy have no restrictions in receiving solar and wind energy. This is particularly useful for a wind turbine, which in this

In this case, the device does not require complex devices to automatically maintain the rotational speed and torque of the wind wheel. The technical solution to the problems of speed and moment control significantly reduces the efficiency of wind energy use. The rotor wind turbine used as a wind turbine of the SVEU, as opposed to the usual blade model, does not require, depending on the wind speed, a change in the angle of attack.

0 blades. As shown by calculations, the efficiency of the rotor propeller is higher than that of the propeller, by 16%.

The hydrogen and oxygen released at the respective electrodes by

5 rafting.

The compressors are driven by pumping hydrogen and oxygen due to the energy of the primary circuit, i.e. from solar panels and wind turbine from the output of converter 3. Hydrogen and oxygen from storage tanks (for hydrogen, from containers with hydrogen hydride) are supplied to engine 9 (internal combustion engine, gas turbine), on the shaft of which a power supply generator 10 is installed (can set via gearbox). Engine 9 can operate on air oxygen, which is safer and allows the SVEU to operate in the mode of an oxygen producing station. Condensed moisture — water is pumped out by a pump 11 fed from a power supply generator 10 and sent back to the electrolyzer 4, providing a closed loop of water movement, significantly saving its consumption. The pump 11 starts up automatically as the condensate accumulates, which is accomplished by the float sensor.

The proposed SVEU is promising in that it can be used with sufficient power as an oxygen and hydrogen generator, which has widespread use in the national economy. The proposed SVEU design can operate in the mode of a gas station for cars and hydrogen vehicles.
