Problems solved by technology

However, the variable pitch technology of vertical axis wind turbines is still in the stage of perfection. Due to the complex structure of this type of wind turbines and the need for wind direction devices, the advantages of vertical axis wind turbines over horizontal axis wind turbines are reduced.

Abstract

The invention discloses a solidity variable wind rotor of a vertical axis wind power generator. The solidity variable wind rotor comprises a chord-length variable blade which is connected with a blade handle and a hub. According to the solidity variable wind rotor of the vertical axis wind power generator, the start-up wind speed of the wind power generator is low, the use efficiency of the wind energy is high, and the use is safe and reliable. The solidity variable wind rotor of the vertical axis wind power generator is applicable to the fields of urban road lighting, the daily power utilization of the grassland and pasture, large wind power stations and the like.

Description

Technical field [0001] The invention relates to a wind wheel of a wind power generator, in particular to a wind wheel of a solidification vertical axis wind power generator, which is mainly used in the fields of urban road lighting, daily electricity consumption of grassland pastures, and large-scale wind farms. Background technique [0002] The solidity of the wind wheel affects the performance of the wind turbine. A low-speed wind turbine with a large wind wheel has a large starting torque, but a low wind energy utilization coefficient. High-speed wind turbines with higher wind energy utilization coefficient have lower solidity and lower starting torque. In order to solve the structural contradiction between the start-up performance of the wind turbine rotor and the maximum wind energy utilization rate, some scholars have carried out research on hybrid wind turbines and variable pitch wind turbines from the perspective of compound wind turbines and dynamically changing blade i...
