Simulation and Test of the Blade Models' Output Characteristics of Wind Turbine

This electronic document is a “live” template. Based on the momentum-element theory, mathematical model of numerical simulation of the output characteristics is set up for resemble models of MW-scale wind turbine blades, which is under a test system with three different setting angles of 10.5°, 30.5°and 50.5°. The initial values of axial and tangential induction factors are determined by Newton-Raphson method, the powers P, power coefficients CP and torque coefficients CM of the three model test systems are simulated by programming in Matlab and Visual Basic. At the same time, characteristic output tests are carried out by in-truck test method of the three model test systems. The results show that each relative error of simulation and testing results of the model test systems is less than 10%; it proves that the simulation method is reliable and the testing results are reasonable.
