FIELD: transport.
SUBSTANCE: invention relates to electric power supply for electrified railways. Proposed system comprises rectifier substations, overhead system, track circuit, power dispatcher unit, GLONASS/GPS unit, and current and voltage control units. Note here that every rectifier station is composed of transformer with feeders, current and voltage transducers, and voltage controller. Rectifier substations are interconnected by overhead system and track circuits. Overhead system is connected with power transformers of rectifier stations. GLONASS/GPS unit, current and voltage control units are installed at rolling stock. Besides, proposed system comprises unit OR and power accounting device mounted at every rectifier station and every rolling stock. GLONASS/GPS unit is connected to AND unit whereto connected are power accounting device, current and voltage control units.
EFFECT: higher accuracy of power consumption accounting.
