Design and Implementation of Phasor Measurement Unit with IoT Technology

Abstract

The phase angle or phase difference is an important parameter in Electrical Engineering because it affects the flow of power in a system. The purpose of this study is to develop a phasor measurement unit and integrate it with IoT Technology. The researchers simulated an electronic circuit using the Proteus software simulation tool, implemented a prototype, and integrated the prototype with IoT. The design works by acquiring the phase difference between the two sinusoidal waveforms. For the experimentation, typical household appliances were used to test if the prototype is working. The measured value of the prototype is verified by simulations and observation of the phase shift shown in the oscilloscope. The graph for Voltage and Current was shown using Excel. Study Cases were also conducted to check if the prototype is producing good results. Simulations and computations were also compared to check the accuracy and correctness of the prototype. Based on the statistical treatment, at the 10% significance level, $0.097> 0.1$, reject $H_{0}$. Therefore, the value of the simulated phase angle is almost the same value of the computed phase angle.
