The suction station "Gnjilan", belonging to the "Water-supply" Pirot municipal
enterprise, has been used as an example of small pump stations energy efficiency
increasing by replacement of existing old pumps with new ones. It has been shown that it
was possible to identify the pipeline characteristic and an optimum system operating
point, even in the absence of appropriate flow measuring devices. This has been done
using an indirect method of flow estimation by measurement of driving induction motor
elecrtical parameters. In accordance with the obtained results, the new pump has been
chosen. Huge savings in the electrical energy consumption referred to actual situation
will be achieved through the application of the new pump. Na primeru Crpne stanice "Gnjilan" u okviru JP "Vodovod" Pirot, prikazan je
način za povećanje energetske efikasnosti malih pumpnih stanica zamenom postojećih
pumpnih agregata novim. Pokazano je da je, čak i u situaciji kada ne postoje
odgovarajući uređaji za merenje protoka, moguće identifikovati karakteristiku cevovoda
i optimalnu radnu tačku sistema primenom indirektne metode merenja električnih
veličina pogonskog motora. U skladu sa identifikovanim parametrima, izvršen je izbor
novog pumpnog agregata čijom primenom se mogu ostvariti znatne uštede u odnosu na
postojeće stanje sistema.
