Purpose and research tasks. Computer calculation progress of electromagnetic processes in the complex electrotechnical systems containing transformers under valve load needing for creation new high-efficiency mathematical models on the base of nonlinear electromagnetic equivalent schemes. Research method - differential and integral calculation, numeral calculations of solution of nonlinear systems of differential and integro-differential equations, matrix and topological methods, approximation of functions, theory of complex variable functions, programming and computer modeling. Practical value of the got results. The mathematical models worked out in this SRW are the base of program complex Colo. A program complex permits to get information about all currents, voltages and magnetic fluxes in the modeled circuit with the help of automatic calculation. Developed by the author scientifically well founded scheme interpretation of modified collocations method for calculation of transients allows to replace the systems of integro-differential algebraic equations of the state by the algebraic equations got by means of Kirchhoff's rules in the special equivalent schemes. The special program complex for the computer calculations of long continuous processes in complex МEES is created on the base of that. The mathematical models and program complex Colo worked out in SRW are used in an educational process at preparation of master's degrees on the electrical engineering faculty of the Zaporizhzhya national technical university.
