Abstract

The paper is devoted to the solution of actual scientific and applied problems of development of scientific and technical basis of optimization and efficient calculation of electrical supply systems of high-power industrial complexes of AC electric furnaces.
The aim of research was to develop the dynamic adaptation method of circuit models of high-current conductors system of AC furnaces and to improve the accuracy and computational efficiency of calculations and correlation of the electromagnetic interaction effects with the electrical parameters of the current distribution in the bus systems.
The system of equations with the conditions of serial and parallel connections of electric circuits, the system of equations for the magnetic energy of these contours, the system of equations of self and mutual inductance contours were proposed for modeling processes in the AC high-current power supply systems of high-power furnaces.
The problem of the relative current error minimization is added, and determination of the adaptation vector projections is realized by the dynamic programming method. It allows to take into account the influence of the electromagnetic processes on the electrical parameters of the power systems of powerful electro-technological complexes of AC electric furnaces.
The experience of numerical realization of the method of circuit model dynamic adaptation of powerful high-current conductors of electric technological systems of AC furnaces shows the significant reduction in the cost of computing resources and time.
This method provides the higher accuracy of calculations as compared with known engineering techniques, and high effectiveness computation as compared with numerical realization of field models
