This paper presents a mathematical model to simulate and analyze electromagnetic transients in transmission lines using a mono-phase representation of these lines comparing results models with and without frequency influence in longitudinal parameters. For this, π circuits and state variables are used for composing a linear system that is solved through iterative numeric routines. This routine is...
Clarkepsilas matrix has been applied as a phase-mode transformation matrix to three-phase transmission lines substituting the eigenvector matrices. Considering symmetrical untransposed three-phase lines and the frequency range into 10 kHz, some transient simulations have been made with the application of this single real matrix. An actual symmetrical three-phase line on untransposed conditions is...
