Analysis of Additional Eddy-Current Copper Losses in Large Converter-Fed Hydropower Generators
Engevik, Erlend Løklingholm; Valavi, Mostafa; Nysveen, Arne (Chapter, 2018)This paper investigates the effect of converter operation on AC copper losses in the stator and damper windings of a large hydrogenerator. Stator currents are computed using finite element simulations. The computed current ... -
Design and Operation Investigations for large Converter-Fed Synchronous Machines in Hydropower Applications
Engevik, Erlend Løklingholm (Doctoral theses at NTNU;2019:194, Doctoral thesis, 2019)The work presented in this thesis deals with design and operation investigations for large converter-fed synchronous machines in hydropower applications. It is shown that the optimal rated frequency that gives the lowest ...
