Studying and optimizing water distribution systems (WDS) is very important for a correct supply of water. These studies can guarantee an adequate water pressure at each location of frequent use and can reduce the total costs of water distribution systems.
The purpose of this paper is to show the possibilities offered by Scilab/Xcos to model hydraulic time-dependent systems. In particular, we develop a new Xcos module combined with the use of Modelica language to show how water distribution systems can be modeled and studied. In this paper we construct a reduced library composed by few elements: reservoirs, pipes and nodes. The library can be easily extended to obtain a more complete toolbox. The developed library is tested on a simple well-known hydraulic system.
Xcos and Modelica codes for the “Hydraulic system toolbox” are available to registered users only. For downloading the library visit: Registered Users Area.
