Wind Turbine Simulator Based on PM Brushless DC Motor
Abstract:The simulations and experiments are carried out for wind energy conversion system(WECS) by using wind turbine simulator in laboratory. In this paper, the mathematic modelling of wind turbine is built according to aerodynamic theory of it, and the reference torque is given under specific wind speed, and the PM brushless DC motor(PMBLDCM) is driven by this reference signal to realize the wind turbine simation. The results under different wind speeds are presented to verify it.
Keywords: wind turbine wind energy conversion system PM brushless DC motor torque characteristic curve
