Online data-driven approach of yaw error estimation and correction of horizontal axis wind turbine

Abstract

Active yaw system is a very important component of modern horizontal axis wind turbines to keep the nacelle aligning with the stochastic wind direction. However, in practice, it is hard to keep the rotor facing into the wind precisely, which will lead to not only the loss in power production but the increment in aerodynamic loads. This study presents a data-driven approach to estimate yaw error for remote terminal unit.
