- W2078997905 abstract "The Centre des Mouvements de l'Eau (CME), operational since 1991 is a centralized Supervisory Control And Data Acquisition (SCADA) system for the water production and distribution network of the Syndicat des Eaux d'Ile de France (SEDIF) which serves approximately 4,000,000 inhabitants around Paris (France). In 1994, the SEDIF and its operator, Générale des Eaux (VIVENDI group) initiated a project called the 'CME-phase II' project with the aim of linking the CME SCADA system with a network analysis software (the Stoner Workstation Service) capable of simulating the hydraulic and water quality operation of the water network. This application is operational since 1997 and provides the SEDIF with a new set of tools to better supervise the operation of the network, predict potential problems in the network and validate different operational strategies. On-line simulations (i.e. in parallel to the real system operation) allows for anomaly detection and resolution: a new set of operational data is received from the SCADA system at a predefined time interval and is used to update the hydraulic model before executing a steady state simulation. Key points in the network can be closely controlled (without supplementary monitoring equipment) and potential discrepancies between calculated and observed data can be detected and analyzed. The entire process is fully automatic and does not require any operator intervention. Off-line past simulations allow the operator to replay an event that took place in the network using the operational data archived by the SCADA system with the objective of better understanding the hydraulic and water quality behavior of the network. Off-line predictive simu1ulations allow the operator to test various operational strategies. Using as a starting point the newest set of operational data and defining the network demand and the facilities operation in the coming hours or days, the operator can initiate a variable simulation and assess the consequences of a specific operational strategy. The CME phase II application is also extensively used to validate any extension or reinforcement project as it permits a quick extraction and validation of SCADA data to calibrate a hydraulic model before assessing the impact of a new extension or reinforcement scheme." @default.
