Development of an HMI Based Smart Power Quality Display

In recent times the modernization of industries has led to the increase of non-linear components in electrical circuits, usage of which has led to a decrease in the power quality; which further translates into losses both financially, electrically, and in some cases, it may also lead to loss of life. Thus, identifying, analyzing, and mitigating power quality issues have become a necessity. Power quality meters can measure some power quality parameters whereas a power quality analyzer can measure and give actionable insights to the user; however, power quality analyzers cost a fortune to the general consumer whereas a power quality meter costs significantly less. The aim of this project was to cover this gap by creating a user-friendly environment around a power quality meter using an HMI which will help the consumer to get actionable insights as well as a graphical representation of power quality parameters. In this project, a smart and user-friendly Power Quality Display, capable of providing graphical insights to the user has been developed using Janitza UMG 96 PQ-L (base power quality meter) and Delta 107EV HMI (Touch Screen HMI). The software DOPSoft has been used to program the HMI and the transfer of data between the meter and HMI has been done with the help of Ethernet.
