DEVICE FOR STRESS BALANCING ON 27_5 KV BUSBARS OF ADJACENT TRACTION SUBSTATIONS Russian patent published in 2021 - IPC B60M3/02 

FIELD: physics.

SUBSTANCE: invention relates to power supply line for vehicles. Stress leveling device on 27.5 kV buses of adjacent traction substations comprises single-phase booster transformer, input single-phase transformer, to its secondary winding there connected in series is single-phase rectifier, smoothing filter, single-phase inverter and output filter. Outlet filter is connected to the primary winding of the booster transformer, and its secondary winding is connected to the cut of the feeder of the contact network at the first traction substation. At that, voltage balancing device comprises inverter control unit, comparator unit, units for determination of voltage vector parameters of first and second traction substations, voltage sensors of the first and the second traction substations, the inputs of which are connected to the secondary winding of the measuring transformers of voltage of the first and the second traction substation and units of formation of the reference pulse of the first and the second traction substations, the inputs of which are connected by communication channels to the system of artificial earth satellites.

EFFECT: technical result consists in improvement of energy efficiency of traction power supply system.
