Abstract
Cilj diplomskog rada bio je izraditi fizikalni model tlačnog sustava u kojem se mjerenjem tlaka i protoka lokaliziraju gubici vode primjenom digitalnog blizanca. U tu svrhu razvijen je numerički model sustava koristeči program EPANET, dok je fizikalni model izrađen od PPR cijevi. Za lokalizaciju gubitaka vode primijenjena je PSO metoda (engl. Particle Swarm optimization). Tako, komparacijom tlakova dobivenih kalibriranim numeričkim modelom za idealno stanje sustava i tlakova izmjerenih na fizikalnom modelu koji ima curenje vode je aproksimiran položaj i iznos curenja vode. Prikupljanje podataka iz fizikalnog modela je provedeno korištenjem ARDUINO pločica i senzora tlaka i protoka koji omogućuju kontinuirano praćenje stanja sustava. Za obradu prikupljenih podataka je korišten programski jezik Python. U demonstracijske svrhe su analizirani različiti scenariji gubitaka vode, uz pet različitih veličina otvora. Rezultati su pokazali da preciznost algoritma ovisi o veličini i lokaciji gubitka.
Abstract (english)
The aim of the thesis was to create a physical model of a pressure system in which water losses are localized by measuring pressure and flow using a digital twin. For this purpose, a numerical model of the system was developed using the EPANET program, while the physical model was made of PPR pipes. The PSO method (Particle Swarm optimization) was applied for the localization of water losses. In this way, by comparing the pressures obtained by the calibrated numerical model for the ideal state of the system and the pressures measured on the physical model that has a water leak, the position and amount of the water leak is approximated. Data collection from the physical model was carried out using ARDUINO boards and pressure and flow sensors that enable continuous monitoring of the system state. The Python programming language was used to process the collected data. For demonstration purposes, different water loss scenarios were analyzed with five different opening sizes. The results showed that the accuracy of the algorithm depends on the size and location of the loss.
