Abstract

The invention relates to the field of wind power generation, and discloses a homodromous double-wind wheel power generation device. The homodromous double-wind wheel power generation device is provided with a homodromous double-wind wheel structure; counter-rotating power generation of a rotor winding and a rotor magnetic pole in a double-rotor structure is finally realized under the reaction effect of a reverse box device. Since the double-wind wheel structure is capable of realizing twice wind sweeping compared with a single-wind wheel structure capable of one-time sweeping, the power generation device has the advantages of improving the collection efficiency and electric energy conversion efficiency of wind energy and reducing the available lowest wind speed, and enjoys a wider application prospect.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a power generation device with double wind rotors in the same direction. Background technique [0002] Wind power generation is a process of converting the kinetic energy of gas flow into electrical energy. Its working principle is to use the wind force of gas flow to drive the wind rotor blades to rotate, and then use the speed increasing device to increase the rotation speed to drive the generator to generate electricity. According to the current wind power generation technology, even a breeze with a wind speed of only 3 meters per second can be used for wind power generation, with a wide range of application scenarios. At the same time, because wind energy is a renewable energy source, and wind power generation does not cause radiation or air pollution, wind power generation has become the new darling of the energy industry today. [0003] Existing wind power generators a...
