Electric power devices electromagnetic modes modelling and analysis

Abstract

A generalized mathematical model of the electromagnetic modes of devices with a laminated core of an arbitrary design with windings created. An algorithm and software implementation of the model developed. Practically important normal electromagnetic steady state modes of reactors’ operation, transient processes occurring at commutation within the winding circuits, non-symmetrical modes determined by non-symmetry of the supplied circuitry, and phenomena originating due to magnetic core magnetization analyzed. Recommendations on electrical processes quality influencing with different magnetization modes provided.
