Daniel von den Hoff takes part in the Conference for Wind Power Drives in Aachen


From 12 to 13 March 2019, the fourth Conference for Wind Power Drives (CWD 2019) took place at the Center for Wind Power Drives in Aachen. As part of his publication entitled "Design and Evaluation of a Battery-Supported Electric Drivetrain for Kite-Based High-Altitude Wind Energy Conversion", Daniel von den Hoff presented current research results, which were developed in cooperation with E.On and other industry partners.



High-altitude wind energy (HAWE) gains more and more interest. The control of kite-based HAWE is widely covered in literature whereas its influence on the power elec-tronic components of the drivetrain has not been investigated so far. In this paper, we present an electro-thermal loss model of the power electronic converters of a kite generator system (KGS). Junction temperatures and converter efficiency are simulated for an exemplary KGS load profile. The required component ratings are calculated with focus on the machine-side converter (MSC) which suffers from application-related stresses. Variable switching frequency and increase of generator pole-pair number are investigated to reduce the MSC power rating.
