| Content Summary | A distributed water supply system is a system based on engineered hydraulic components which conveys water from the source to the consumers. A typical distributed water supply system consists of the water sources, a pipe network, storage facilities like reservoirs and water tanks, pumping stations and the consumption nodes. This Thesis is based on the project "An Intelligent system for sustainable management of water supply networks: application in the island of Crete", which was submitted for the purposes of the program GR02.03 - "Integrated marine and inland water management - Good environmental status in European marine and inland waters" and was funded by the European Economic Area grants 2009 - 2014 (EEA grants 2009 -2014). In this project, the distributed water supply system of the Organization for the Development of Crete S.A. (OAK.AE) was examined. The first part of this Thesis deals with the operation and the flow control of the main pumping station of OAK.AE water network, named "Vlites". In an extended set of simulations, by using "SmartWaters" framework, four control algorithms are examined as they indirectly control the operation and the flow of "Vlites" pumping station, by tracking the level of the feeding tank, named "Korakies". In detail are examined: i) an algorithm based on pumping station’s pumps scheduling control (ON/OFF) under constant speed operation and tank level control, ii) an algorithm based on pumping station’s pumps scheduling control under variable speed operation and tank level control, iii) an algorithm based on a PI controller and tank level control iv) an algorithm based on a PID controller and tank level control. Algorithms (i) and (ii) were implemented by the team of the scientific project. Algorithms (iii) and (iv) are implemented in this Thesis framework. The second part of this Thesis deals with the development of an algorithm for big water leakages localization (greater than 20-25 m3/h), in OAK.AE distributed water network. Initially, an examination about the accurately simulation of water leakages in "SmartWaters" framework takes place, by simulating a leakage in a prototype network and verifying the accuracy of the leakages modeling. The algorithm is based on, a set of features, which are generated by pressure signals from an extended set of simulations in "SmartWaters framework", in order to extract features and examine which of them can be used for leakages detection. These features are: i) the discrete energy of the pressure signals ii) the entropy of the pressure signals and iii) the energy of detail coefficients of Daubechies 2 (db2), 3d level discrete wavelets decomposition. | en |
