Analysis of polarized linear electric network with two-reactance components

This paper introduces the concept of polarized linear electric network and proposes a new approach to analyze it. It is well-known that the internal impedance of salient-pole generator has two reactance X_d, X_q corresponding to the direct and quadratic current components. Two different reactance possessed by one circuit element provide the polarization characteristics in the current transfer. This study proposes a new analysis method which shows that the linearity of the polarized linear network makes it possible to calculate generator currents in one step for the given internal voltages and rotor angles of the generators. Tests have been performed for the sample systems, which shows remarkable improvement in computation time
