Implementation of SCADA Through Cloud Based IoT Devices - Initial Design Steps

The aim of this work is to develop Internet of Things (IoT) device in place of remote terminal unit (RTU) and integrating it with cloud based SCADA. SCADA systems are used for monitoring the power utilities. The data that is monitored is spanned across a geographical area. The data capture is done by the RTU which are physically located at places where the meters are available. Data on real-time basis will be updated in structured databases for the use of operators. The operators will then use this information and take required actions at the control center. Existing SCADA systems usedeedicated Local Area Network (LAN) as computing environment for servers along with dedicated communication network and protocols for Data Exchange. In addition they make use of computer based RTUs for data collection from field devices. In this paper we present a similar architecture where physical RTUs and data exchange centers are replaced by IoT devices and various other AWS services thereby improving the efficiency of the SCADA systems. This work sets a floor for implementing SCADA using IoT and cloud services.
