Features Of Field Simulation Of Electromagnetic Processes Of The Trolley’s Busbars

A mathematical spatial model was created to analyze electromagnetic processes within the steel trolley of the busbars, focusing on the time formulation of the electromagnetic field distribution problem. To enhance computational efficiency and reduce both dimensionality and calculation time, we’ve introduced a two-dimensional, plane-parallel mathematical model in the frequency domain for studying the electromagnetic field distribution. In order to consider the nonlinearity of magnetic properties in steel trolleys, we suggest establishing an effective magnetization curve for the nonlinear two-dimensional electromagnetic field problem associated with the busbar. The verification results obtained, as indicated by the calculated voltage drop, substantiate the high precision of the calculations and the reliability of the results obtained. The error, in this case, remains within the range of 1.88% to 2.06% for the two-dimensional model in the frequency domain, in comparison to the spatial model in the time-dependent electromagnetic field formulation.
