Prediction of high frequency characteristics of the windings of large electrical machines: a lumped-parameter reluctance-network analysis

A lumped-parameter reluctance-network approach is presented for the analysis of the high-frequency characteristics of machine windings such that the terminal impedance of the machine can be obtained and that subject to any known excitation, the internal currents and voltages in the machine can be as...

Description
Summary:A lumped-parameter reluctance-network approach is presented for the analysis of the high-frequency characteristics of machine windings such that the terminal impedance of the machine can be obtained and that subject to any known excitation, the internal currents and voltages in the machine can be assessed. In this analysis, the impedance of the machine is taken to comprise three separate components; capacitance and inductance contributed from energy stored within the coil surface, inductance due to magnetic flux which passes through the machine laminations and end winding effects.
