Research Associate (m/f/d) - Nacelle LIDAR Measurements in Complex Terrain

The Fraunhofer-Gesellschaft (www.fraunhofer.com) is one of the world's leading organizations for application-oriented research. 74 institutes develop pioneering technologies for our economy and society – more precisely: 30 000 people from technology, science, administration and IT. They know: Anyone who comes to Fraunhofer wants to and can make a difference. For themselves, for us and for the markets of today and tomorrow.

Then join the Wind Site Assessment Group and support us in the BMWE-funded project “Development of nacelle-based methods for performance verification and yield enhancement of wind farms in complex terrain (ELISE).”

Increasing the power output of existing wind turbines is crucial for further boosting the share of wind power in Germany’s electricity mix. It is not uncommon—especially in complex terrain—for actual yields to deviate from predicted yields. Currently, post-installation measurement in complex terrain requires site calibration using measurement masts, which is too time-consuming and too expensive. The goal of the ELISE project is therefore to develop a nacelle lidar-based method for measuring power characteristics in complex terrain at a manageable cost and in a short amount of time. The Fraunhofer IEE is focusing in particular on more accurately determining turbulence intensity using nacelle lidar. To this end, methods will be developed that are based on a spectral approach and combined with an empirical approach for deriving correction factors for turbulence intensity. Wind field modeling in complex terrain also plays a role in this context.
