Abstract


The current state of development of the power semiconductor technology of domestic production for problems of smooth start-up and frequency regulation of powerful electric drives of alternating current is considered. Power and dynamic characteristics of the converting equipment of various topology of construction with the analysis of physics of electromagnetic processes in electrical machines are presented. On concrete examples of executive mechanisms of a megawatt class possibilities of devices of smooth start and frequency regulation of parameters are illustrated. Options of integration of devices of the converting equipment into ACS are offered by technological processes. The analysis of influence of indignations in network on the powerful electric drive with pump and compressor loading on a shaft is made.
