Abstract

In Korea, a high speed train called as KTX (Korea Train eXpress) has started the revenue service since 2004. For KTX train, the current feed thyristor based on converter and inverter system is used as a traction system. So it is the source of the massive harmonics, and makes worse the power factor of the railway power line. Therefore it is needed the compensator or harmonic filter to improve the power quality of the railway power systems. In this paper, the 6 MVA single-phase active power filter for high speed train in Korea installed at the substation of the railway power system is introduced with the real data.
