Mathematical models of adjustable electric drives of direct and alternating current of load-lifting machines.
Abstract
The relevance of the study of emergency modes of TP-D drives of constant and frequency converter AC of load-lifting machines has been substantiated. The requirements are formulated that must be met by mathematical models that allow investigating both operating modes and emergency modes, including those caused by a sudden disconnection of the supply voltage. The capabilities of the developed models are illustrated by examples.
