Hydraulic modeling of pump systems in water distribution networks |
Secondary abstract: |
Water distribution networks provide water supply to consumers. Pumping system adds mechanical work, thus providing sufficient amount of energy for water distribution throughout network. Pump's mechanical work is made by consuming electrical power. Because consumption of electricity and costs of consumed energy are high improvements made on operation of pumping system can lead to non negligible savings. When optimising pump system's operation different factors have to be taken into account (hydraulic laws, consumption pattern, changes of tariff of electricity) while trade off between energy consumtion costs at one hand and number of pump switches (and thus related pump maintenance costs) at the other hand is always present. Following this criteria several solutions exist which create solution space. According to these and other requirements, specific to a problem, one of possible solutions is chosen. |

Abstract (ePrints): |
Cevovodna omrežja skrbijo za distribucijo vode do porabnikov. Črpalni sistem v obliki mehanskega dela dodaja potrebno energijo za transport vode po omrežju; črpalke porabljajo električno energijo, ki jo spreminjajo v mehansko delo. Količina porabljene električne energije in s tem povezani stroški so veliki, zato lahko z izboljšanjem delovanja črpalnega sistema v določenem obdobju privarčujemo vsoto, ki ni zanemarljiva. Na optimiziranje delovanja črpalnega sistema vpliva več dejavnikov (hidravlične zakonitosti, vzorec porabe, spreminjanje tarife električne energije), poleg tega pa moramo tehtati med nasprotujočimi si cilji (stroški porabljene električne energije v enem dnevu ali dnevni obratovalni stroški ter
število vklopov in izklopov črpalk in z njimi povezani vzdrževalni stroški). Glede na te kriterije obstaja več optimalnih rešitev, izmed katerih izberemo tisto, ki je za določeni problem najboljša. |
