This paper examines the effect of wind turbulence on the performance of both a nearly constant speed wind turbine (induction generator) and one designed to operate at variable speed and at optimum tip speed ratio (alternator). Specifically, a computer simulation of wind turbulence is generated for various mean wind speeds and turbulence levels and is then used as input to a wind turbine model which includes the effect of rotor inertia in its response. Output from the simulation includes power output and efficiency in both bin analysis and average value formats. Results indicate that turbulence may be a significant factor in, (1) predicting annual power output, (2) analyzing experimental data, and (3) designing for optimum performance.
