Modern methods for balancing of single phase loads when feeding a.c. electrified railways
Artikel i övriga tidskrifter, 2017

© DIV Deutscher Industrieverlag GmbH / Vulkan-Verlag GmbH - 12/2017. Conventional compensation circuits for phase balancing of single phase AC railways for 50 or 60 Hz have high cost for the associated transformers. A new version of the classical Steinmetz scheme, using three single phase transformers connected as a W with the phase angles -60°, 0° and +60°, can reuse the two standard single phase transformers of a V-connected feeding station with a third identical transformer added. Power factor compensation can easily be included. For neutral sections between different feeding systems, a neutral section converter is proposed.
