Wind speed regulation system applicable to wind driven generator

Abstract

The invention relates to a wind speed regulation system applicable to a wind driven generator, which comprises an ultrasound wind climate sensor, a main controller and a driving device, wherein the main controller is connected with the output end of the ultrasound wind climate sensor, and the driving device is controlled by the main controller. The wind speed regulation system is characterized by comprising 1 to 100 bodies in parallel distribution, wherein each body comprises a U-shaped keel, a transmission mechanism and a sail, the transmission mechanism is arranged on the U-shaped keel, and the sail is connected with the U-shaped keel. The wind speed regulation system has the advantage of controlling the wind speed of the wind driven generator through regulating the self inner diameter so that the wind power is sufficient and maintains the constant state.

Description

technical field [0001] The invention relates to electric power equipment, in particular to a wind speed regulating system suitable for wind power generators. Background technique [0002] With the advent of the era of low-carbon economy, the use of natural energy such as wind energy, solar energy, and tidal energy is becoming more and more extensive. Wind turbines are increasingly being installed on buildings or in mountains to harness wind energy. Usually, the starting wind speed of large fans is 3 m / s, and the rated wind speed is 13-14 m / s. The starting wind speed of small and medium-sized fans is 1.5 m / s, and the rated wind speed is about 12 m / s. However, in most areas, the wind speed cannot reach more than 10 m / s all the year round, resulting in low efficiency of wind turbines and shortening the service life of wind turbines. Promotional use. In order to solve this problem, the small and medium-sized fans that have appeared in recent years have continuously reduced th...

Problems solved by technology

However, in most areas, the wind speed cannot reach more than 10 m / s all the year round, resulting in low efficiency of wind turbines, shortening the service life of wind turbines, and even failing to reach the start-up wind speed of the wind turbines, so that the wind turbines cannot be obtained in this area. promotional use

In order to solve this problem, the small and medium-sized fans that have appeared in recent years have continuously reduced the starting wind speed of the fan to facilitate popularization. However, the promotion of only improving the performance of the fan without adjusting the wind speed is still limited.
