Abstract

Real time monitoring of power system is essential for its continuous and reliable operation. This paper presents a low cost, low power consuming system that can be used for quick and accurate power system parameter monitoring under smart grid environment. The designed system will continuously measures, processes and display the power system parameters like voltage, current, phasor difference, power factor, power consumption using ultra low power microcontroller. Measurement of power system parameters of resistive and inductive loads are monitored using PIC16F877A microcontroller. Sampling theorem is used to calculate the phase difference between voltage and current utilizing zero crossing detectors. Simulations of the voltage, current, phasor difference were done using NI Multisim software.
