SINTEF Energy Research
Andrzej Holdyk is currently a Research Scientist with SINTEF Energy Research, Trondheim, Norway. His research interests include simulation of electromagnetic transients, high-frequency interaction between electrical components and transient phenomena in offshore wind farms. He received the M.Sc. degree in information processing for control from Silesian University of Technology, Gliwice, Poland, in 2008, and the M.Sc. and Ph.D. degrees in electrical engineering from the Technical University of Denmark (DTU), Kgs.Lyngby, Denmark, in 2009 and 2014, respectively.
• Typical resonance frequencies in 33 kV collection grids
• How the resonance frequencies change when we go up to 66 kV?
• Main resonance frequency – what does it depend on?
• Possible implications for harmonic and transient behaviour
