Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a single-pole double-micro wind power generator group supporting system. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free renewable energy source. The development of wind power generation will not only contribute to the low-carbon transformation of energy, but also help improve energy security capabilities. Traditional wind turbines are large in size, noisy, and have high requirements for wind power. Micro-generation is a technology that uses wind energy to generate electricity, using wind wheels to convert wind energy into mechanical energy, and then converting mechanical energy into electrical energy through generators. The principle of a micro power station is similar to that of an ordinary wind power station. The difference is that a micro power station uses a smaller wind wheel, which can be exposed to wind all day and all night. The existing micro generators are difficult to produce and install, and the cost is high. When using a group of micro wind turbines, they occupy a large area and are small in number, noisy, and have strict site selection requirements, making it difficult to truly achieve full popularization.
