Application of rule-based logical controls in network hyduaulic models

摘要

A knowledge-based system methodology is proposed for simulating the complex operational dynamics of hydraulic network models in a real-time operating environment.The system applies a comprehaensive rule-based control language to permit more flexibility in the ways that operation of water distribution networks can be simulated.The contorl rules are defined using fuzzy and ocmbinatorial logic derived from operational experience.the logicla contorl scheme provides the fundamental basis of knowledge management of the system control.The fuzzy logicla contorl readily exploits the tolerance for imprecision and uncertainty for greater robustness in modeling.THe approach can be appleid to all tyeps of wate rdistribution models and can be added directly into existing network modeling software.the resultifng computer models are directly amenable for simulating real-time SCADA systems operation.The SCADA interface leads to automation in system operations and control by providifng on-line data updates to the hydraulic and water quality modle as a means of both calibrating the model and checking operational changes and what-if scenarios.The method should prove useful to every water utility attempting to optimize water distribution system operation and performance.
