PLIO: a generic tool for real-time operational predictive optimal control of water networks

摘要

This paper presents a generic tool, named PLIO, that allows to implement the real-time operationancontrol of water networks. Control strategies are generated using predictive optimal controlntechniques. This tool allows the flow management in a large water supply and distribution systemnincluding reservoirs, open-flow channels for water transport, water treatment plants, pressurizednwater pipe networks, tanks, flow/pressure control elements and a telemetry/telecontrol system.nPredictive optimal control is used to generate flow control strategies from the sources to thenconsumer areas to meet future demands with appropriate pressure levels, optimizing operationalngoals such as network safety volumes and flow control stability. PLIO allows to build the networknmodel graphically and then to automatically generate the model equations used by the predictivenoptimal controller. Additionally, PLIO can work off-line (in simulation) and on-line (in real-time mode).nThe case study of Santiago-Chile is presented to exemplify the control results obtained using PLIOnoff-line (in simulation).
