This paper presents the extension of theory and results of a new real-time digital simulator of transmission line that is applicable to the frequency-dependent parameters. This simulator is based on Marti's time domain formulation which is adopted in EMTP program. Improvements are made to speed up the calculation to realize real-time digital simulation. It obtains the electromagnetic transient performance of unbalanced three-phase line in real time. Sample results of a single line to ground short circuit on an open-ended three-phase transmission line are presented. The real-time digital simulator results are verified for accuracy by simulating the same system, off line, on EMTP program.
