Compressed air energy storage type mini-type wind driven generator

Abstract

A compressed air energy storage type mini-type wind driven generator comprises a draught fan body portion, a gas energy storage portion and an energy storage conversion portion, wherein a draught fan main shaft between a wind wheel of the draught fan body portion and the generator is provided with a draught fan driving wheel and a draught fan clutch; the gas energy storage portion is mainly composed of a gas storage main shaft, an air compressor, a gas storage pipeline and a gas storage tank which are sequentially connected; the gas storage main shaft is provided with a gas storage driving wheel and a gas storage clutch; the gas storage driving wheel corresponds to the draught fan driving wheel; the energy storage conversion portion is mainly composed of an outgassing pipeline, an outgassing motor and an outgassing main shaft which are sequentially connected together; the outgassing pipeline is connected to the gas storage tank; the outgassing main shaft is provided with an outgassing driving wheel and an outgassing clutch; the outgassing driving wheel corresponds to the draught fan driving wheel; the draught fan body portion, the gas energy storage portion and the energy storage conversion portion are controlled by a controller, so that three states that the draught fan body portion generates power by itself, the draught fan body portion drives the gas energy storage portion to operate to store energy, and the energy storage conversion portion drives the draught fan body portion to generate power are achieved.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a compressed air energy storage type miniature wind power generator. Background technique [0002] Wind power generation is a power generation technology powered by wind energy that exists in nature. It has the advantages of cleanliness, environmental protection, and sustainability. upsurge. [0003] Since the wind generators for wind power generation are driven by wind energy, the wind generators have specific requirements for wind energy. Under normal circumstances, the required start-up wind speed of wind turbines is 2.5-3m / s (that is, the degree of breeze), and the required shutdown wind speed is >17m / s. That is to say, when the natural wind speed is lower than 2.5m / s, the wind turbine driven by it cannot start normally; when the natural wind speed is higher than 17 m / s, the safety and stability of the wind turbine driven by it will be reduced. It will be seriously threatened, ...

AI Technical Summary

Problems solved by technology

Although this technology relies on wind energy to achieve power generation and compressed air energy storage, it not only has defects such as complex structure, difficult manufacturing, and poor running stability; moreover, the energy storage of compressed air can only be realized when the generator is overloaded, that is, At higher wind speeds, only rely on the vortex compound machine to share the overload of the generator, but the generator does not need to be offline. Therefore, at high wind speeds, when both the generator and the vortex compound machine are fully loaded, the excess load cannot dismounting, which poses a serious threat to the safe and stable operation of the wind turbine, and the reliability is poor
