On April 7, 2022, we were glad to have @FL from the University of Stuttgart, SWE present at the 5th Wind & Drivetrain Conference 2022.

Fiona LÜDECKE is an engineer for renewable energy systems and is currently working as a researcher at the Stuttgart Wind Energy Department of the University of Stuttgart.

Her Ph.D. research focuses on electro-mechanical interactions in wind turbines using Simpack. 

Furthermore, Fiona works on the WINSENT project. The project aims to build two research wind turbines in the complex terrain of the Swabian Alps, where Fiona is responsible for the set-up and validation of the models of the turbines in FAST and Simpack.

Abstract:

The nominal power of newly installed wind turbines increases steadily in wind energy.

Current publicly known industry developments are aiming for 14 MW. Such concepts are intended for offshore applications, where any component with intense maintenance needs must be avoided. Therefore, most of these concepts use direct-drive configurations. Direct-drive generators with such nominal power are huge, leading to heavy assemblies.

Research now investigates the mass reduction potentials by reducing passive material in generators. This may lead to changes in structural behavior and system stiffness.

In standard generator constructions, the generators from a wind turbine perspective are assumed to be rigid assemblies with no rotor eccentricity. Therefore, the influences of the electromagnetic field on other turbine components are neglected. This assumption needs to be cross-checked for ongoing research. This can only be achieved with strongly coupled co-simulation of the electromagnetic field and the mechanical system.

Therefore, this presentation introduces a newly developed software coupling of Simpack and COMSOL Multiphysics using the Simpack User Routines.
