Abstract: This document presents the experimentally determined power generation efficiency for the drive-train and motor of a 20 kW experimental ocean current turbine. This efficiency assessment was performed using a custom designed dynamometer and covered much of the generator’s expected operating range. These measurements are used with numerically modeled rotor performance to predict the overall efficiency of the ocean current turbine when converting kinetic energy flux to electric power.
