FIELD: electricity.
SUBSTANCE: invention relates to power supply for electric networks contacting with current collectors of vehicles. Method of traction power supply system strengthening consists in fact that by means of traction voltage source traction station is supplied with this voltage to traction network, and also power accumulator is connected to traction network. Energy accumulator is made in the form of a hydraulic accumulator traction power station, which is placed on the line. Note here that pump and generator parts of hydraulic accumulator traction power plant are preferably made separately.
EFFECT: technical result consists in reduction of non-uniformity in time of traction load energy consumption for overhead system.
