IoT Enabled Power Quality Monitoring in Substations Through LoRa LEO Satellite Communication

This paper explores the convergence of Internet of Things (IoT) technology with Low Earth Orbit (LEO) satellite communication for power quality monitoring in substations. A 7-day experiment utilizing a LEO satellite, exemplified by DEWASAT-1, demonstrates the viability of this approach. The findings highlight the potential for continuous monitoring of critical substation assets with a multi-satellite constellation. The system leverages LoRa (Long Range) communication technology, which is a low-power, long-range wireless protocol ideal for IoT applications. LoRa enables efficient and reliable data transmission from substation sensors to satellites, ensuring seamless connectivity even in remote or challenging environments. The integration of IoT, LoRa, and satellite communication technology enhances the efficiency of power quality monitoring and ensures data connectivity resilience. This research paves the way for developing robust and responsive power quality monitoring systems, contributing to the evolution of smart infrastructure and resilient IoT applications in power systems.
