DEVICE FOR COMPENSATION OF REACTIVE POWER OF ELECTRIC STOCK Russian patent published in 2018 - IPC B60L9/12 H02J3/18 

FIELD: electrical engineering.

SUBSTANCE: device for the compensation of the reactive power of the electric rolling stock is intended to increase the power factor of the consumers, in particular, the electric rolling stock of alternating current with zone-phase voltage regulation. Device for compensating the reactive power of the electric rolling stock contains a multiwinding voltage transformer with three secondary windings connected with the load from the rectifier-inverter converter and the motor, a compensator comprising at least one reactive power source configured as LC circuit, two current sensors, two voltage sensors, a synchronizing pulse unit, a rectifier, an inverter, a booster transformer, an inverter control unit interconnected in a certain way.

EFFECT: technical result consists in increasing the p_f power factor electric locomotive by adjusting the reactive power of the compensator both in terms of the capacitive and inductive components of the reactive power of the compensator.
