FVA-Nacelle: Project Successfully Finalized, Further Research Initiated

The FVA-Nacelle project - focused on researching stresses on wind turbine (WT) drivetrains - has been finalized and the Digital Twin has been established while the FVA-Nacelle is preparing the path for further research.

The interdisciplinary research conducted in the FVA-nacelle project focused on the analysis and reduction of local stresses in the electro-mechanical drivetrain of wind turbines: in cooperation with Siemens and the Forschungsvereinigung Antriebstechnik e.V. (FVA), over the course of three years, the Center for Wind Power Drives (CWD) has successfully researched a fully validated Digital Twin and hence provided validated simulation models; the latter make it possible to calculate local stresses on WT components. The validation of simulation models was accomplished by the help of the “FVA-nacelle” – a research WT equipped with measuring technology and implemented at the CWD test bench. The simulation models that had been created simultaneously have been validated by measurements of local as well as global variables and are currently researched further. Due to its sensors within the electrical part of the drivetrain alongside its freely customizable settings of its parameters, the FVA-nacelle can be optimally utilized for analyses on the system test bench:   project CertBench compares and evaluates concepts for testing electrical voltage dips by the means of fault ride-through (FRT) tests; it centers on the comparison of converter-based system voltage dips that are generated by currently used FRT containers. The development of a condition monitoring system aimed at early estimating the risk of White Etching Cracks emerging in gear roller bearings lies at the heart of project ProNOWIS: here, the FVA-nacelle allows for the innovative sensor system to be tested by operating the test nacelle under real conditions that lead to White Etching Cracks. This way, researchers avail of the unique possibility to optimize the condition monitoring system based on the real system.
