Experimental researches of two-zonal speed control thyristor electric drives with improved energy characteristics

The disruption of the two-zonal speed control developed systems is presented. They provide the improvement of energy index of rolling mills thyristor electric drives at the expense of redistribution of the thyristor converter EMF rectification reserve in stable and dynamic modes. The description of the laboratory set is given. The results of experimental researches, varifying the opportunity of EMF rectification reserve reduction are represented (introduced).
