Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a composite energy system that simultaneously collects gas mechanical energy and thermal energy. Background technique [0002] Wind is a kind of new energy with great potential. At present, the main way of wind energy collection is wind power generation. The working principle of wind power generation is that the wind wheel rotates under the action of the wind, and the kinetic energy of the wind is converted into the mechanical energy of the wind wheel shaft, and the generator rotates and generates electricity under the drive of the wind wheel shaft. Wind turbines are generally composed of wind turbines, generators, direction regulators, towers, speed-limiting safety mechanisms and energy storage devices. Wind power generation has the characteristics of clean, green and renewable, and has attracted more and more attention from countries all over the world. However, traditiona...
