Semi-physical experiment platform for wind power generation

Aiming at the complicated conditions of wind farm, this paper proposes a semi-physical simulation system that can simulate the operation of wind turbine under laboratory conditions. First, gives simulated wind velocity that based on ARMA and statistical wind velocity model, and then utilizes field data to make power spectrum correction. Second, Basing on the combination of the wind wheel, transmission shaft, gearbox, variable pitch system, and the pulse characteristics of pneumatic torque, a simulated method, from input wind speed to output torque of asynchronous motor is given. The results show that the feasibility of this method.
