Using Sensitivity Analysis and SCAD A/Model Comparisons to Diagnose Model and System Issues

摘要

Water distribution system computer modeling has long been a vital tool for system operations, capital planning and engineering design. Water distribution models typically rely on data collection from SCADA systems to provide reference data for model calibration, However, by loading snapshots of SCADA system data directly to the hydraulic model, both operational and model calibration issues can be diagnosed. A comparison of model predictions based on real-time operating conditions and SCADA flows and pressures allows utility personnel to immediately identify situations where the model and SCADA data diverge.
