loT Based Real-Time Harmonic Monitoring System for Distributed Generation

Renewable sources integration with power grid and Distributed Generation (DG) has resulted into Power Quality deterioration problems. There is a need for continuous monitoring of Harmonic injection in real-time. In this paper, we propose an end to end system based on an IIoT value chain that remotely monitors harmonic injection into grid. Entire system is built and tested on Industrial grade equipments. Monitoring is done on a remote device over MQTT via Cloud. Measurement results which are presented in real-time are compared to an EN50160complaint meter.
