Резюме:It has been established that the complex Thevenin’s circuit equivalent does not adequately reproduce such energy characteristics of the AC primary circuit as active power and power factor. A new one-port equivalent circuit of linear AC electrical network is proposed, which is equivalent to the primary network in terms of complex power and reproduces its complex volt-ampere characteristic on a pair of selected terminals. Analytical relationships are justified for the element parameter calculating of the proposed equivalent circuit based on the complex ZE parameters of the primary network in terms of contour currents. The results of linear AC electric network modeling in the time domain fully confirmed the adequacy of the new complex power conservative equivalent circuit structure and the analytical method for determining its parameters in reproducing the energy characteristics of the primary network in the open and closed modes of the selected terminals, as well as for a specific load.
