The electromagnetic compatibility of superconducting and traditional electrical equipment is analyzed, with particular attention to their electromagnetic interaction and their mutual influence on system performance. Means of shielding and positioning the equipment so as to minimize disruptions are identified. We have proposed approaches to numerical simulation and developed nonlinear numerical models for analysis of the interaction between the electromagnetic fields generated by superconducting and traditional electrical equipment, with unlimited propagation of the magnetic field, in the absence of spatial symmetry of the field distribution. To determine the influence of electromagnetic fields on the integral parameters of superconducting and traditional electrical equipment, an algorithm and corresponding software is developped. Optimal parameter values and dimensions of superconducting inductive reactors in smoothing filters for tractional substations are determined, such that the space required is minimized and the superconducting material with specified energy capacity is used to maximum efficiency.
