Embodiment Construction

[0035] The invention provides a wind turbine blade and a structural design method thereof. In order to make the objectives, technical solutions and effects of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0036] like figure 1 As shown, it is a structure design method of a wind turbine blade according to a specific embodiment of the present invention. The design method includes:

[0037] S100, using the Weibull function model to estimate the wind speed, and determining the starting wind speed and the rated wind speed according to the distribution curve of the function model.

[0038] Generally, in real life, the wind speed varies greatly, and it is difficult to accurately describe it with a mathemati...

Abstract

The invention discloses a wind power generator blade and a structural design method thereof. The structural design method includes A, estimating the wind speed by a Weibull function model and determining the starting wind speed and the rated wind speed according to a distribution curve of the function model; B, setting the tip-speed ratio, the blade number, the wing section and the wind wheel diameter of the blade; C, calculating to obtain the chord length, the installing angle and the wing section of the blade based on a Wilson method. The structural design method obtains supplementary important parameters for blade structural design by analyzing the blades through dynamics theories and studying and designing the blades in critical positions of a wind power generator in details from deriving the wind speed, selecting the blade number and the wing section to wind wheel diameter calculation.

Description

technical field [0001] The invention relates to the technical field of wind turbines, and in particular, to a wind turbine blade and a structural design method thereof. Background technique [0002] With the continuous increase of human demand for energy and the emergence of problems such as environmental pollution and greenhouse effect caused by fossil energy, energy security has become the most important issue faced by all countries in the world. Wind energy is currently the most promising renewable and clean energy for development and utilization, and wind power generation has attracted much attention as the main way of wind energy utilization. In addition to Taiwan, my country's cumulative installed wind power capacity has reached 44 million kilowatts, surpassing the United States to become the largest wind power country in terms of installed capacity. The domestic wind power market has entered a stage of rapid development, and the market space for wind power developmen...
