Accounting for electric power losses in transformers, DC traction substations
The article presents an analysis of the total consumption of electrical energy of DC traction power supply system. We describe the parameters included in the total consumption. An electrical calculation using the existing program “KORTES” ( “The complex calculations of traction power supply”) in the feeder zone “Prosvet-Malinovka” of South-Ural Railway at various modes of traction substation. The results of calculation revealed the inaccuracy of electric energy losses in the buck and converter transformers. The method of determining the electric power losses in transformers is offered.
