PID Controller applied in a water distribution network supplied by pumping direct

Abstract

Rapid growth in population over last few decades has resulted in changes of supply system consumption patterns. Such, require effort from companies in technical aspects; targeting need of strategies to improve operational efficiency. Management system, based on automated control, carries a strong mechanism to gauge these results. Aim of this paper is to present a comparative study of both hydraulic and electric parameters of an experimental automated network. Network behavior was analyzed under two conditions: without use of controller and with Proportional-Integral -Derivative (PID) controller. Results indicated efficiency of applied controller in different consumption scenarios. Dealing with energy efficiency, it was verified that, according to calculations related to specific energy consumption (SEC), reduction on electrical energy is notable with use of controller.
