The Study of the Performance evaluation and Structural analysis of 2KW Wind Turbine Blade

To face of cut carbon and reduce costs is the global trend；green energy industry has become a new hot industry around the world. After a national long-term research and development, wind power equipment has been gradually becoming more mature. Compared to the huge market of large-scale wind turbines and technological barriers, small wind turbine market diversity of uses has also been favored. Small wind power industry in Taiwan has been gradually formed, in the wind turbine parts, such as blades, generators, bearings, towers, control systems and related component makers have possess with a high level of technology. But after the actual test runs at the National Penghu University Wind Park by the monitoring platform, shows that many turbines through the measured data is difficult to achieve in line with the original offer, and some cannot achieve even the basic safety factor. In view of this, the main purpose is to analyze the blades correspond with the manufacturers information and provide analysis and simulation methods, hoping to compare with the manufacturer’s data.
The analysis used in this paper is divided into two parts; the first part is the accuracy of the analysis blade results, second part analysis the blade structure. First, the power factor (Cp) can be obtain by CFD software Fluent, and using two-dimensional software Foilsim to verify the results of CFD, and compared with manufacturers data. Fluent can calculate its optimum power factor under each wind speed corresponding to RPM (rotation per minute). The second part, using the finite element software (ANSYS) calculated the stress distribution on the blade, in this article assumes that three common blade material, aluminum, glass fiber and carbon fiber. The simulation calculated different wind speeds vary from low to high and observe the blade stress distribution. After considering the maximum stress, blade tip deformation and manufacturing costs, the glass fiber in the production of blades is more appropriate.
