FIELD: electricity.
SUBSTANCE: invention refers to power factor improvement for consumers, in particular, for alternate-current electric stock with zone-phase voltage regulation. The declared invention contains voltage transformer, load, source of reactive power that represents in-series connected inductance L, capacitance C and two back-to-back thyristors, voltage sensor, current sensor, sync pulse unit, control unit, unit of pulse and phase control, unit of controlled current calculation, unit for calculation of actual current value and comparator.
EFFECT: technical result involves maximum increase of power factor kp for electric locomotive up to 0,95 due to consideration of both phase shift angle φ (per 0,03) and consumed current waveform distortion factor v (per 0,08).
