Environment-friendly efficient intelligent wind power generation system

Abstract

The invention provides an environment-friendly efficient intelligent wind power generation system. Wind shields are arranged, and an air guide groove is formed between the two wind shields to guide wind to flow out of the side face, so that the wind energy utilization rate is better increased, and a larger torque force is also achieved. Wind from the side face is shielded, a horizontal transmission shaft is driven to rotate under the action of wind force, and the wind power utilization efficiency is further improved. In addition, the system can adapt to any-time changes of the wind direction.Wind shields capable of partially covering side frames are further arranged, so that the wind which is inclined towards the side face is conveniently blown into impellers, the impellers are driven torotate, and the wind power conversion efficiency is improved; and a wind adjusting plate is arranged, the counteractive wind is blocked and prevented from entering the impellers, the useless work is prevented, and the wind power conversion efficiency is improved. The wind power generation system is low in manufacturing cost, small in occupied space, convenient to transport, more environment-friendly and low in noise, does not cause damage to flying birds near a wind field and can generate electricity through breeze, and the generating capacity under the same wind field condition is 3-6 times that of the horizontal axis.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an environment-friendly, efficient and intelligent wind power generation system. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time. attention from all over the world. [0003] The current wind power generation system generally includes an impeller, a transmission assembly and a generator set. The impeller is driven to rotate by external wind, and the transmission assembly is used to drive the generator set to generate electricity. The rotation axis of the impeller of the horizontal axis wind turbine is parallel to the airflow direction and the ground. Its main advantage is that the wind rotor can be erected at a higher place from the ground, thereby reducing the influence of ground disturbance ...

Problems solved by technology

But in reality, the wind direction and wind speed are changing all the time, so wind energy is unstable. How to stabilize the output power of wind turbines is an important issue in wind power generation technology.

As the size of the wind rotors in modern wind power generation systems is getting bigger and heavier, when the wind direction changes, the empennage or the rectifier control the impeller to align with the wind direction and respond slowly, making it difficult to keep up with the changing rhythm of the wind direction. There is a certain angle in the current wind direction, which leads to low wind power conversion efficiency and unstable force on the impeller, resulting in rapid wear and tear of the entire equipment and reduced service life; in addition, when the wind speed changes, the output power of the wind turbine also changes with the The change, resulting in unstable output power
