FIELD: transport.
SUBSTANCE: invention relates to electrified railway transport and aims at perfecting system of electric power record. Proposed system comprises voltage and current transducers mounted at first and second transformer substations and connected to intersubstation zone contact wire feeders to transmit signals proportional to measured voltage and current to station control hardware. Data transmission stations and network to transmit data to data accumulation and processing devices are mounted at electric locomotive. Current and voltage transducers are connected to locomotive control device. Note here that both station and locomotive control devices are interconnected via radio channel built around two radio modems. Data transmission from electric locomotive to traction substation is carried out in electric locomotive passing substation in direct radio access zone. GLONASS system is used to define current coordinates of electric locomotive, reference electric power consumption schedule to traversed track profile and define deviation from optimum train handling. Synchronisation of time count at traction substation and electric locomotive is carried out by GLONASS perfect time system.
EFFECT: higher accuracy.
