The predictions of the different magnetic core losses with acceptable accuracy are key parameters for temperature-rise calculations for any considered up-rate in large hydro electrical machines. In this paper, an overview of existing magnetic core loss models is reported. A new approach for the computation of the magnetic stator and rotor core loss is proposed. Finite element electromagnetic simulations...
Predictions of the different magnetic core losses with acceptable accuracy are key parameters for temperaturerise calculations for considered up-rate in large hydro electrical machines. In this paper, available core loss model is used to compute the electromagnetic core losses in large hydro electrical machine during no-load and short-circuit modes. The obtained results are discussed and compared...
The predictions of the different magnetic core losses with acceptable accuracy are key parameters for temperature-rise calculations for any considered up-rate in large hydro electrical machines. It is common practice for hydro electrical designers to compute the core losses in different section of the machine function of the flux density given only at 60 Hz by the manufacturer of the steel lamination...
The hydroelectric generation industry faces two related challenges: increasing the output the existing hydro electrical generators but without reducing the reliability of these aging facilities. Many aspect of hydroelectric generator should be considered during any up-rate study. Magnetic losses of the stator and rotor core may change significantly with any load increase. The open and short circuit...
