In WECS, the graph of wind power utilization coefficient and blade tip speed ratio is obtained: wind energy utilization coefficient = torque coefficient * blade tip speed ratio blade, Cp = Ct * λ.
The torque coefficient is the polynomial function of the blade tip speed ratio, Ct=a6*λ^6+a5*λ^5+...+ a1λ+a0,a0... the value of a6 can be found in some books on wind power generation and Therefore, the wind power utilization coefficient Cp is also a polynomial function of the speed ratio of blade tip Cp=a6*λ^7+.....a1λ^2+a0λ Then the wind energy utilization coefficient of WECS and the wind energy utilization coefficient Cp. The blade can be drawn through some software, such as MATLAB. Top speed ratio graph.
I hope this can be useful to you
1. First, draw the mask style headbande Sanxingdui carried by "Qingqing", holding a rattle in his hand, and the main element of the turbine on the surface of the drum. "Rotor", the motif symbolizes the production of hydroelectric energy.
2. Second, draw "Yuanyuan" wearing a hairpin with a sun wheel pattern on his head and holding a windmill in his hand, which is a symbol of wind power generation.
3. Finally, draw the bodies of "Qingqing" and "Yuanyuan". "Qingqing" and "Yuanyuan" are designed with elements of the national treasure giant panda and Sanxingdui, highlighting the ancient Shu culture of Deyang, where the conference is held.
