SIMULATION AND EXPERIMENTAL RESULTS OF HARMONIC DISTORTION IN A Δ-YΔ TRACTION TRANSFORMER OPERATING IN HELLENIC SUBWAYS

摘要

In this paper, divergences are identified concerning the elimination/limitation technique of the produced higher order harmonics in traction systems, via experimental results. A simulation of a multi-winding transformer carried out, based on real data derived from measurements in a DC traction substation, by using the PSCAD/EMTDC simulation software. The results of the simulation are in agreement with the theoretically expected and the experimental ones.
