STUDY ON STARTING MODE OF POWERFULL ASYNCHRONOUS MOTORS

Abstract

The report presents results of a simulation study of powerful asynchronous electric drives of submersible pump aggregates. The voltage failures on the power bars in the start-up mode of power-proportional asynchronous electric drives with the power transformer are evaluated. Based on the analysis, a rational technical and economical solution for controlling the start-up mode of such electric drives is proposed. The voltage failure at the given power ratios of the power source is limited consumers and minimizing its negative impact. This is achieved through the justified use of soft starter actuators.
