INCREASED EFFICIENCY OF ELECTRIC DRIVE COMPLEX OF PROCESS EQUIPMENT OF MINING PROCESSING PLANT
The problem of significant power consumption and current distortion of the supply network by a complex of frequency-controlled electric drives of technological electric installations of an industrial enterprise is considered. Disclosed is a method of switching a diode rectifier with an active current filter to a transistor rectifier, for generating a sinusoidal current in a supply network, as well as for two-sided energy exchange, between a complex of electric drives and a network.
