Cloud Based Data Acquisition via IoT for Electric Power Quality Monitoring

Abstract

© 2019 IEEE. This paper presents the usage of Cloud and IoT technology in data acquisitions for power quality analysis. Cloud technology allows measuring devices to work using IoT infrastructure, where devices over the Cloud are networked on the Internet and can quickly and efficiently transfer information about the state of power quality in power network. The initial information provided by the measuring devices is the measured active and reactive power, as well as the magnetizing current harmonic content. The collected data are stored in the Cloud, where later accurate and transparent data analysis is possible with the aim of estimating the DC voltage offset in power network, which most commonly appears as the result of a photovoltaic power grid on the network.
