ABSTRACT:
A traction power supply system in which one, two or three single-phase traction loads are supplied from a 3-phase high voltage system. Balancing of the load in each phase of the high voltage system and reduction of reactive currents in that high voltage system is achieved by simulating any further single-phase load or loads necessary to make the number up to three and providing individual controllable balancing circuits for all of the single phase circuits together with individual harmonic filters designed to include accommodation of the harmonic currents generated by the balancing circuits.
