The self and mutual parameters and the coupling between phases are modeled using modal transformation techniques. The modal representation is developed from the intrinsic consideration of the modal transformation matrix and the resulting system of time-domain differential equations is described as state equations. Thus, a detailed profile ofthe currents and the voltages through the line can be easily calculated using numerical or analytical integration methods. However, the original contribution of the article is the proposal of a time-domain model without the successive phase/mode transformations and a practical implementation based on conventional electrical circuits, without the use of electromagnetic theory to model the coupling between phases. © 2003-2012 IEEE.743-748englumped elementsMutual couplingstate equationstransmission line theoryAnalytical integrationComputational modelElectromagnetic theoriesLumped elementModal representationModal transformationState equationsDifferential equationsElectric fieldsElectric linesEquations of stateNumerical methodsTime domain analysisTransmission line theoryLinear transformationsArtigo10.1109/TLA.2013.6533963WOS:000320720900010Acesso restrito2-s2.0-848799364144830845230549223
