Abstract :
In circuits with nonlinear nonstationary and parametric elements during calculation of power processes there exist an important problem of a correlation optimization between calculation accuracy (accuracy of result presentation) and computing expenses. The analysed example showed that analysis of exchange processes in the systems with rectifiers, showed the presence of mathematical correlations which can describe the level of electromagnetic compatibility of separate rectifier with all of the system. That is why subsequent expansion of the developed model can give the instruments of estimation of electromagnetic compatibility level for more complex systems with the wide spectrum of equipment. hi paper generalized algorithm of estimation of the inter-influence of electric elements is presented. Authors offered to perform the analysis of energy exchange processes in circuits with nonlinear nonstationary and parametric elements on the basis of the extended system of power descriptions and on the selection of equivalence classes of power processes.
