Abstract
One of the trend lines while perfection of the electromechanical and electro-technologies for the mining, oil and gas extraction industries is the development and utilization of the efficient frequency drive control systems consisting of the asynchron electrical machines. The models of drives with vector and scalar control are given for the comparable investigation of efficiency dynamic and of the asynchrony machine's power factor under frequency-regulation. The results of the transient modelling for the drives with 4A280S6 motors are presented, obtained using MatLab.
