The application of numerical simulation in the output power of concentrated wind energy turbine set

Take the special wind turbine generator system with concentrated device as the object of study, after analyzed the operating characteristics of the whole system, a mathematic model for the output power characteristic of the concentrated wind energy turbine set is established. On the base of Windows XP, and with the high level programming language Visual Basic, a simulation software system is developed. Calculations and numerical simulations of the concentrated energy wind turbine power under different wind speed, atmosphere temperature and density have run on this simulation system. Then experiments with the in-truck test are carried out under the same conditions. By the study and analysis on the results of the simulation and the experiments, it shows that the results of simulation and the experiments are consistent with each other very well, and the correctness of this numerical simulation method is proved, thereby providing a common simulation method for different special devices of the wind turbine. At the same time, the main factors influencing the output power are presented. (C) 2011 Published by Elsevier Ltd.
