Compacting Distributed Parameter Transmission Line Model In Emtp-programs
2004 Ieee/pes Transmission And Distribution Conference And Exposition: Latin America. , v. , n. , p. 196 - 200, 2004.
The present paper proposes a compact representation for the transmission line models based on modal transformation. The distributed parameter TL model present at the majority of the electromagnetic transient programs is taken into account. The proposed model takes advantage of the similarities between non-homopolar modes and applies complex numbers theory to manipulate the state variables in modal domain. The proposed method is applied to a single-circuit three-phase line represented through the distributed parameter model (EMTP). The resources used promote a reduction of both the number of operations by iteration and the allocation of states, optimizing the procedure and increasing the processing speed of simulation. © 2004 IEEE.196200Wedepohl, L.M., Application of matrix methods to the solution of traveling-wave phenomena in polyphase systems (1963) Proc.
