Dobrovolska O. Improving of the operational management of water supply and distribution in real time

The thesis is devoted to improvement of process of management of streams in systems of giving and distribution of water of municipal systems of water supply on the basis of application of a technique of reasonable definition of quantity and an arrangement of control knots, definition of the actual expense in network pipelines on the basis of measurement of pressure in control knots in real time. For the solution of this task methods of mathematical statistics, experimental measurements in a network are used; mathematical modeling of streams in system of water supply on personal computers with use of packages of application programs, in particular, hydraulic calculations of systems of water supply. The practical value of work consists in a possibility of use of the received scientific-theoretical results at determination of the actual volumes of water in pipelines and places of emergency leaks according to measurement of pressure in limited quantity of points of a network. The mathematical model of determination of the actual parameters of system of water supply by results of simultaneous measurement of pressure in limited number of her knots is developed. Analytical dependences for calculation of the sizes of zones of insufficient pressure in a network taking into account a relief of lands for various modes of a water consumption are received. Methods of definition of the actual expenses of water on sites, arrangements of zones with insufficient pressure in networks and detection of considerable leaks by results of measurement of pressure in separate knots are based on actual data. The mathematical model of hydraulic calculation of systems of water supply on the basis of measurement of pressure in the limited number of knots is developed for creation of the general distribution of water on all sites. The developed method of definition of emergency sites is used for detection of the damaged sites in water supply systems of the Hortitsky district of the city of Zaporizhia that has allowed to reduce emergency leak of water and to gain economic effect of 311000 UAH/year.
