FIELD: transport.
SUBSTANCE: proposed device relates to electrified railways and can be used to reduce influence on electrified railways on adjacent communication lines. Generation of compensation effect signal (compensation current) is ensured by independent source, that is, a source not related with influence source. For this, proposed system incorporates control signal generation unit and parallel processing of harmonic components of interference to be compensated by correcting their phases and amplitudes. Said generation unit represents also a unit designed to set tolerable or preset minimum amplitudes of harmonics to be compensated. Harmonic composition of the unit as well as that of compensating current are selected depending upon compensations objectives. System operates in open cycle to allow stability.
EFFECT: higher efficiency of compensation and stability.
