Projects:2019s1-191 Microcontrollers for the Measurement of Power Quality

Introduction

Power quality is a measurement of standard reliability of voltage, frequency, pure sinusoidal waveform and uninterrupted supply in electric power systems. As power network evolves, involving the usage of non-linear loads in power networks which made the power quality problem becomes more acute which is the possible of a part of power network become disengaged or known as "islanded". The islanding power network may cause issues on voltage and frequency which the problem in electric power system can be indicated by the changes of Rate of Change of Frequency (RoCoF) which could indicate instability in power systems. On the other hands, the recent development of microelectronics which made powerful computational power available at very low cost. There are much more possible ways to reduce this problems and one of those is by early detection which this project is to make an early indicator to detect Rate of Change of Frequency (RoCoF) using a microcontroller with embedded Phase-Locked Loop integrated circuit to estimate Rate of Change of Frequency (RoCoF) by measuring Real and Reactive Power, Power Factor, Power Angle and Harmonics.
