IIOT in Utility Operations Paper

Thakur, Varun / Mogha, Abhinav

In this paper, we have explicitly described about the needs, implementation methodologies, and challenges being faced in Internet of Things (IOT) solutions adoption in Tata Power-DDL operations. Utilities have been trying hard to optimize Operational and Capital expenditures to achieve higher operational efficiencies and improved performance indices. A Smart grid roadmap was adopted by TPDDL and technologies like Substation and Distribution Automation, SCADA/ADMS, GIS, AMI, DSM, Smart Meters, Communication Infrastructure and RF Canopy have been successfully implemented. Early technologies in TPDDL different verticals have dedicated centralized smart systems with field devices are often appeared to be locked into purpose built, non-interoperable solutions. As uses and requirements multiplied, the complexities and obstacles to integrate these SILOS of technologies are becoming more and more challenging. The Internet of Things (IoT) is creating huge opportunities in Power Utilities, adding value to both the Utility and the Consumer. IOT or Cloud based solutions which utilizes all three technology verticals i.e. IT, OT and Communication infrastructure break open the new era of “Digitalization and Data Analytics” in Power Industry. In TPDDL, we have implemented IOT innovations which are helping us to drive down the cost in Operations and Maintenance and Project Execution. Case I—IOT based communication system to conduct an Integrated-Factory Acceptance Test. I-FAT plays an important role to ensure timely completion and quality execution of a project. However, OEMs are still reluctant to conduct the IFAT because most of their equipment’s are being manufactured at different geographical locations. An IOT/Cloud based wireless communication was established between two OEMs locations and complete integration and protection testing was carried out using a pair of 4G enabled Modems. Site commissioning of project carried out effortlessly with record time. Case II—Remote secure access of SCADA network for Work from Home. During the tested times of Covid-19, an IOT based cyber secure wireless connectivity was established by which Automation and Protection maintenance teams could able to connect with Grid Automation devices to perform critical activities like Fault Data recorders downloading during faults, IED breakdowns rectification, RTU and relays configurations. Case III—IOT cloud based Power Transformer Residual Life Assessment system. This system is being used to fetch critical performance parameters of transformer like DGA, Oil and winding temperatures, Moisture content and further data analytics. Smart Grid may be viewed as IoT for electric power 1.0. Critical processes and Assets health can now be monitored more accurately using IOT enabled digital data collection and analytics. Connected technologies and operations can reshape the way Utilities operate, allowing them to make smarter and more informed decisions.
