LOCOMOTIVE REGENERATIVE POWER SUPPLY SYSTEM WITH FEEDBACK AND ANTI-ICING FUNCTION AND CONTROL METHOD Russian patent published in 2019 - IPC B60M1/12 B60L7/10 H02G7/16 H02H7/122 

FIELD: electricity.

SUBSTANCE: group of inventions relates to power supply lines. Locomotive regenerative power supply system with feedback and anti-icing function consists of two regenerative supply units with feedback. Positive DC electrode of the regenerative power supply unit with feedback is connected to the positive electrode bus of the transport network of the subway. At the same time positive electrode bus is connected to ascending contact network and descending contact network, respectively, through first switching device and second switching device. Negative DC electrode of the regenerative power supply unit with feedback is connected to the descending or ascending contact network through the third switching device and to the negative electrode bus of the transport network of the subway through the fourth switching device. Also disclosed are methods of controlling described system.

EFFECT: prevention of contact network icing due to regenerative electric energy.
