Analysis of magnetic forces and vibration in a converter-fed synchronous hydrogenerator
Valavi, Mostafa; Nysveen, Arne; Nilsen, Roy; Le Besnerais, Jean; Devillers, Emile (Chapter, 2017)This paper investigates the influence of converter-fed operation on magnetic forces and radial vibration in a hydrogenerator. Flux density distribution is computed using time-stepping finite element (FE) analysis and used ... -
Influence of Converter Topology and Carrier Frequency on Airgap Field Harmonics, Magnetic Forces, and Vibrations in Converter-Fed Hydropower Generator
Valavi, Mostafa; Devillers, Emile; Le Besnerais, Jean; Nysveen, Arne; Nilsen, Roy (Journal article; Peer reviewed, 2018)This paper investigates the effects of converter-fed operation on magnetic forces and vibration in a hydrogenerator. The variable-speed hydrogenerator (in a pumped-storage power plant) is a large synchronous machine with ...
