Device and control method for preparing wind energy, ocean energy and solar energy

Abstract

The invention discloses a device and a control method for preparing wind energy, ocean energy and solar energy, wherein the device comprises a fan, an impellor, a solar battery pack, a storage battery, a commercial power interface, an air tank, an air compressor, a sensor, a transmission and a controller, the corresponding transmission gears are selected according to the real-time pressure of the air tank, so that a drive electromotor can operate within the rotation speed range with the highest efficiency so as to reduce the number of air compression stages required without the transmission; the instability of energy supply of wind energy, ocean energy and solar energy can be eliminated by adopting commercial power supplement measures, and a flywheel is arranged between an electromotor and the air compressor, thus the rotation speeds of the electromotor and the air compressor can be more stable; and meanwhile, direct-current electricity energy is provided for the drive electromotor of each stage of air compressors by utilizing the wind energy, ocean energy and solar energy, the complementation of multiple kinds of renewable energy sources is realized, the instability of single renewable energy source is relieved, and greater available power can be obtained.

Description

technical field [0001] The invention belongs to the field of renewable energy utilization and storage, and in particular relates to a device for preparing compressed air by using wind energy, ocean energy and solar energy and a control method for the compressed air preparation device. Background technique [0002] Energy and the environment are one of the major issues of sustainable development that human beings must face. It is the consensus of scientists from all over the world to develop and use clean and renewable energy. At present, the main renewable energy sources on the earth are solar energy, hydro energy, wind energy, ocean energy and biomass energy. [0003] Solar energy refers to the radiant energy of sunlight, which is the main source of renewable energy. Solar energy is rich in resources, free to use, no need to transport, and has no pollution to the environment. It is widely used to generate electricity or produce hot water. [0004] Wind energy is the kinet...
