COMPENSATED SYSTEM OF POWER SUPPLY FOR REMOTE ELECTRIC ENERGY CONSUMERS Russian patent published in 2015 - IPC H02J3/12 H02J3/16 

FIELD: electricity.

SUBSTANCE: in a compensated power supply system for remote electric energy consumers comprised of a supply mains in the form of a three-phase alternating-current source and a three-phase power transmission line (PTL) with p-phase rectifiers connected at the line end to output leads, to which the electric energy consumers are connected, at the input of p-phase rectifiers there is an auxiliary parallel passive filter of characteristic harmonics and the three-phase PTL is split and in splits there are auxiliary three-phase transformer correcting devices (TTCD), each of them comprising three-phase regulating and compensating transformers based on self-contained magnet cores; primary three-phase winding of the regulating transformer containing in each phase the main part and the regulating part with taps is connected by ends of phase windings phase-by-phase to the commencement of circuits consisting of in-series primary phase windings of the compensating transformer and phase capacitor banks connected by ends to one of the taps in the regulating part of the phase winding at the primary three-phase winding of the regulating transformer; at that commencements of the phase windings of the primary three-phase winding of the regulating transformer are coupled to the power transmission line phase-by-phase before splitting and phase-by-phase connected in-series secondary windings of the regulating and compensating transformers are coupled to the power transmission line phase-by-phase upon splitting. TTCD are switched on either in PTL commencement, at intermediary point, at PTL end or at PTL commencement and end. The invention can be used for the supply with alternating-current energy of remote consumers, for example, as power supply systems for oil and gas drill rigs.

EFFECT: potential effective power supply for remote electric energy consumers through the alternating-current power transmission line with large values of active and inductive resistance.
