The Features of Calculation of Heterogeneous Electric Circuits Described by Macromodels

A new approach for calculation of heterogeneous electric circuits with lumped and distributed parameters described by discrete macromodels is provided in the paper. The MATLAB/SIMULINK software environment is used to implement the specified problem. The proposed approach is illustrated with the example of a two-winding transformer loaded by a long line. This approach can be used as a method for the fast transients' analysis in complex hybrid electrical circuits that provides sufficient adequacy of the results obtained with minimum computational effort.
