Enhancement of Energy Efficiency of Pumping Plants at Water Supply and Wastewater Disposal Systems

Summary

One of the ways of enhancement of energy efficiency of pumping plants at water supply and wastewater disposal systems introduced successfully at the Municipal Unitary Enterprise Gorvodokanalof Novosibirsk is considered. The matter is the introduction of high-voltage stations of frequency control of pump units with power voltage of 6–10 kV. Variants of frequency regulation and experience in their introduction at pumping stations are presented. The experience in operation of the stations of frequency control demonstrates their high efficiency not only in power saving but also concerning the rest operational indices including provision of the stable and guaranteed water supply to all consumers in particular.
