Abstract

The study aimed to design a supervisory control and data acquisition (SCADA) system to control solar power plants for clean water irrigation system during the dry season in remote areas. The SCADA system contrived is expected to be able to meet the main elements of the SCADA architecture. Accordingly, following steps were conducted, starting from designing the human machine interface (HMI) in the master station (MS), mapping out the microcontroller as a remote terminal unit (RTU) and designing the communication path between MS and RTU. Furthermore, the SCADA system was tested by the system test to evaluate the SCADA system that was designed meet minimum standard and running well. After tested, the result showed that the system is successfully designed to meet the main elements of SCADA architecture. The system is also able to monitor and control remotely, resulting in more efficient control of user work as well as rapid decision making in order to minimize damage potential when an interruption occurs. For both control and monitor, the MS and RTU in the SCADA system wirelessly communicate.

Highlights

  • A geographically suitable supervisory control and data acquisition (SCADA) system is urgently needed when implemented to remote areas

  • The first element is the design of master station (MS) which is focused on human machine interface (HMI), the second element is the design of the remote terminal unit (RTU) and the third element is the design of communication lines

  • Apart from that, solar power plant system planning is needed. This plan aims to determine the size of the solar power plants system that is controlled by the SCADA system so that the specification of the SCADA system can be determined

Summary

Introduction

A geographically suitable supervisory control and data acquisition (SCADA) system is urgently needed when implemented to remote areas. There are some report based on literature review showed the progress of research [1] ─ [10] From these studies, general elements of SCADA architecture are explained. Regarding on the SCADA architecture, studies [1] ─ [4] showed that the SCADA system generally has 3 main important elements, including RTU as data collector from the field, MS as monitor and control, and communication line to the link between RTU and MS. This study is successfully designed SCADA system that can effectively control and monitor to solar power plants, provide the desired information in the form of measurement quantities, reporting, historical logging and data recording. Thereafter, the communication lines testing is conducted to provide information about the distance range between MS and RTU to communicate wirelessly
