Abstract
A problem associated with DC traction substations is the nonrobustness of the passive filters used for the filtering of the harmonics induced by the substation´s 12-pulse rectifiers. These harmonics cause problems with the communications and the signalling on the DC railway lines. Interference with the railway signalling system can have serious and sometimes fatal effects. Therefore, a method is being devised by which the problematic harmonics can be compensated for by means of an active power filter (APF) on the DC-side of the substation´s 12-pulse rectifiers
