DC TRACTION SUBSTATION WITH FLYWHEEL STORAGE Russian patent published in 2017 - IPC B60M3/06 H02J15/00 F03G3/08 F16F15/30 

FIELD: electricity.

SUBSTANCE: DC traction substation with a flywheel storage includes a power transformer, rectifier, a smoothing filter with a reactor, flywheel storage, an energy conversion, control and redistribution unit, current and voltage sensors. The conversion, control and redistribution unit include an automatic drive that is connected to the storage and to an automatic transfer box. The transfer box is connected to a DC motor, a DC generator and a three-phase generator by means of shafts. The motor and the DC generator are connected to the positive and negative buses of the traction substation via semiconductor switches. The three-phase generator is connected to the three-phase supply network through a semiconductor switch unit. In this case, the control leads of the automatic drive with an automatic transfer box, all semiconductor switches are connected to the corresponding terminals of the control unit, to the inputs of which the terminals of the current and voltage sensors and the terminal of the storage charge level sensor are connected.

EFFECT: improving the safety and reliability of the traction substation.
