Modeling water supply system control system algorithms

This paper introduces a control system model framework built into EPANET simulator. The control system model extends the current possibilities offered by EPANET to model the exact, dynamic behavior of the water distribution system working under complex or high-level control system.Besides the control system model, a novel method for modelling parallel pumping stations in EPANET was developed. The new methodology allows varying the control type (pressure, flow) and setting to dynamically change during the simulation. The new pump battery component was utilized in the control system modelling.The new modelling tools were demonstrated in a case study.
