SCADA based intake monitoring for improving energy management plan: Case study

Abstract

Intake is one of the most important pumping stations in water treatment plant (WTP) and greatly effects the overall plant efficiency. Intake mainly consist of high-tension (HT) motor pump such as vertical turbine pump and submersible pump. The required power supply for intake is generally fed from the main grid through distribution company/department. At the same time, high operational cost of the diesel generator (DG) power back up source results in a huge burden. Also, internet of things (IoT) and Supervisory control and data acquisition (SCADA) based system is widely used nowadays. Therefore, study regarding monitoring strategies of intake is very important and is rarely to be found. In this paper, monitoring strategies of Greater Aizawl Water Supply Schemes phase II is studied. The main objectives are; to study and analyze pump energy consumption (viz. Feeder Current, Frequency etc.); to implement ladder logic for monitoring energy parameters using MOVEREAL. The study shows monitoring of intake energy parameters as well as the feeding substation, showing that SCADA can be efficiently used as an energy management plan.
