A LabVIEW based power analyzer

Poor power quality affects the functioning of utilities, industrial units, productions, system performance, customer services and operating cost. There is an ever increasing need for power quality monitoring systems owing to the growing number of sources of disturbances in AC power systems. Thus, a real-time signal detection and harmonic analysis is of great significance to provide power quality solutions. In this paper, a power quality monitoring system is developed by designing Virtual Instruments (Vis) using LabVIEW™. Power quality parameters such as instantaneous power, active and reactive power, power factor and harmonics are all presented.
