Description
Summary:Computation of electromagnetic transients on transmission lines involves estimation of the propagation and characteristic admittance (impedance) matrices over a wide frequency range. State equations approximated from these two transfer matrices are used for time domain simulation of various transient phenomena. It is shown that a reduced order model can be obtained by using an improved estimation methodology. The developed approach reduces the number of the state equations to be solved, and consequently provides a significant saving on the computational effort in the time domain analysis of three phase networks with multiple circuit transmission lines.< >
