Analysis of Self-Starting Modes of Pumping Motors
Abstract
Considered transients in coasting modes when the pump lost the drive, as well as self-starting asynchronous electric drive of the pump unit. In order to improve the technical and operational indicators of meliorative pumping stations, the necessity of using the self-starting mode of electric drives of pumping plants is justified. The results of field studies of unsteady processes during self-starting electric motors at pumping stations are presented. The simulation of transient processes in self-starting modes of an asynchronous electric drive of a pump unit is considered with the aim of identifying the nature of the change in supply, head and moment of resistance on the pump shaft in the marked modes
