FIELD: electrical engineering.
SUBSTANCE: according to the method, the energy of higher harmonic currents, which include currents of one or several fixed frequencies, is extracted from the power flow of the grid in the form of equivalent energy of unidirectional repeated width-modulated pulse sequence. The duration of these pulses is measured according to the change law of the abovementioned group's current signal envelope curve. The energy is extracted via a fully controlled solid state PWM rectifier.
EFFECT: increase of efficiency and reliability, decrease of resource intensity.
