PIPELINE NETWORK MODELING AND SIMULATION FOR INTELLIGENT MONITORING AND CONTROL - A CASE-STUDY OF A MUNICIPAL WATER-SUPPLY SYSTEM

This paper reports on an extended-period simulation for predictions of the flows and pressures of a municipal water supply system. The progr am has been developed within the scope of the Real-Time Intelligent Sy stems Project at the University of Regina, Saskatchewan, Canada. The a im of this project is to develop a real-time decision support system f or monitoring and control of the water pipeline network operations. Th e system supports the operator's decision-making in maintaining the di stribution pressures of water at the pumping stations at all times. Th e system consists of three modules: an expert system module, a water d emand predictions module, and a pipeline network simulation module. In this paper, we describe the simulation module which has been implemen ted using the Hardy-Cross and Newton-Raphson methods. The programs wer e implemented in MathCad and FORTRAN. A comparison of the two implemen tations is presented, and some results from the simulations are descri bed.
