Wind power generator unit for automatically regulating blade angle according to strength of wind power

Abstract

The invention relates to a wind power generator unit for automatically regulating a blade angle according to strength of wind power, belonging to the technical field of wind power generation. The wind power generator unit comprises more than three wind power generators; each wind power generator comprises a generator tower base, a generator, a generator shaft, a blade seat arranged on the generator shaft, and two to three blades arranged on the blade seat. The wind power generator unit is characterized in that more than one wind speed and wind direction measuring and signal converting and transmitting device is arranged on the area or periphery of the more than three wind power generators; blade angle regulating devices are arranged on the generator shaft; the blade seat and two to three blades; and the wind power generator is provided with a reception and conversion controller for wireless reception of signals of the wind speed and wind direction measuring and signal converting and transmitting device so as to control the blade angle regulating devices for changing blade angles along with the change of wind speed. According to the invention, the blade angles can be automatically regulated according to the wind power strength so as to adapt to a wider wind scale range, reduce the investment of wind power generation equipment and improve the power generation efficiency of the wind power generator unit.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind power generator set that automatically adjusts the angle of the blades according to the wind force Background technique [0002] According to the article "2012-2016 China Wind Power Industry Investment Analysis and Prospect Forecast Report" on China Investment Consulting Network, as a clean and renewable energy, wind energy has attracted more and more attention from all over the world. The total amount of resources is about 2.74×10 9 megawatts, of which available wind power is 2×10 7 megawatts. China's wind energy reserves are large and widely distributed, with great potential for development and utilization. In 2010, China's newly installed wind power capacity reached 18,928 MW, accounting for 48% of the world's new installed capacity, surpassing the United States and becoming the world's largest wind power market. However, a major problem in...

Problems solved by technology

However, this technical solution is only applicable to "wind generators" with 24 or more sets of blades in the fan, and this technical solution cannot be applied to "wind generators" with 2 to 3 blades that are most used.

In addition, the "wind generator" with 2 to 3 blades also has the problem of low power generation efficiency under the same wind force because the angle of the blades cannot be changed.
