Повышение надежности частотно-регулируемого электропривода каскадных систем стабилизации давления насосных станций

Abstract

Based on the analysis of cascaded control units pumping station with the launch of motors from one inverter, consider the problem of reducing the reliability of the system in case of extinction voltage in the mains. With a synthesized virtual model studied the behavior of the system in the case of a momentary power failure. Simulation results are given advice on the rational use of uninterruptible power supplies low power for uninterrupted power supply coils of power contactors, which increases the reliability of the system un- der consideration the electric drive pumps.
