FIELD: railway transport; electrified railways.
SUBSTANCE: according to proposed method, amplitudes and phase of harmonics causing maximum psophometric action composing compensating current and which should be compensated are tuned simultaneously by two independent channels. Tuning is done by search signals of amplitude and phase by minimum difference between corresponding harmonics which are formed from interference signal and signal of standard minimum amplitudes which are formed additionally. Stability at compensation without traction and, consequently, compensating current is provided by presence of additionally formed harmonic components. Said components feature minimum amplitudes tolerable by criterion of quality of compensation and are equivalent to harmonic components of interference, traction and compensating current signals.
EFFECT: improved efficiency of process of compensation of harmonics of traction current causing maximum psophometric action onto communication line adjacent to traction system owing to improved stability and quick response of interference compensation system.
