COMPENSATED SYSTEM OF POWER SUPPLY FOR ELECTRIC ENERGY CONSUMERS Russian patent published in 2014 - IPC H02J3/02 

FIELD: electricity.

SUBSTANCE: in the power supply system there is a coupled parallel passive filter of characteristic harmonics, at the input of a three-phase power supply line there is a coupled three-phase step-up regulating transformer while at the line output there is a three-phase transforming compensator that contains a three-phase step-down regulating transformer, a three-phase compensating transformer and a three-phase capacitor bank, all installed at independent magnet cores. At the input of the ρ-phase rectifier there is a coupled parallel passive filter of either ρ-1 harmonics or ρ-1 and ρ+1 harmonics. The invention can be used, for example, as a power supply system for remote oil and gas drill rigs.

EFFECT: arrangement of effective and safe power supply of consumers through the alternating current power supply line with large values of active and inductive reactance and simultaneous improvement of energy indicators and quality in the power supply system.
