Parameters Determination of the Trolley Busbars by Electromagnetic Field Simulation

Abstract

The mathematical model of electromagnetic processes in basbar’s trolleys, which taking into account the design parameters, the nonlinearity of magnetic properties, the influence of harmonic components of currents and voltages, is proposed. Based on mathematical model implementation, a technique for calculating electrical parameters and characteristics of busbar’s trolleys was proposed. The influence of harmonic current components on the active power losses was estimated. The presence of harmonic current components, which limits of the standard leads to an additional increase in losses by 3%. However, when the standardized values are exceeded, their effect increases on the active power losses.
