Electrical distribution networks of railway junctions. problems and solutions

The article describes the current state of railway non-traction electric power supply system in the electric grid complex. The main drawbacks of the existing electricity metering system in 0.4-10 kV distribution networks are shown. The main directions of non-tractive electric grid complex innovative development are considered, including directed to increase the efficiency of electric energy transformation, transmission and consumption processes due to the management of distribution networks operating modes. The basic principles of "Digital district power supply" constructing are given.
