YawDyn research project

Project title: YawDyn – Validation of yield increases and load reductions in offshore wind farms by adapted dynamic wind direction tracking.

Summary:

Content and Methodology:

For the first method, ForWind is developing stability-dependent yaw control based on SCADA data. Here, the threshold values of the yaw control are dynamically adapted to the current flow conditions. The aim is to optimize the wind direction tracking with respect to the load on the yaw drive and power of the WT for the respective environmental condition. The second method is based on the concept of “passive wake deflection” developed by ForWind. This is being further developed by ForWind and prepared and parameterized for implementation in the WTG control system at the BO1 offshore wind farm. The method reduces the number of yaws of an upstream WT, causing a deliberate slant flow, which deflects the wake, reducing turbulence and shadowing effects on a downstream WT. ForWind will publish the methodological and scientific results and thus contribute to risk minimization in the application of novel methods for aerodynamic wind farm control in the use of offshore wind energy.
