Power Quality Monitoring using Virtual Instrumentation & LABVIEW

Abstract

This Paper principally portrays that a Power Quality Monitoring system utilizing LabVIEW is created. Because of the higher utilization of power converters and other nonlinear burdens in industry and by customers all in all, it very well may be noticed an expanding crumbling of the power frameworks voltage and current waveforms [1]. The paper ‘Power Quality Monitoring using Virtual Instrumentation and LABVIEW’ basically depicts the monitoring of the quality of the power generated during the process with the help of a virtual environment that is LABVIEW. Now this paper is very much simple and is based on finding the power factor along with Active, Reactive and Apparent Power. In additional to that Active/Apparent and Reactive Energies is also found out and the nature of the graph is also found out accordingly. Here we are using Current and Voltage Transformers as the basic transducers and ideal values of voltage and current is taken and the graph is plotted with respect to voltage/current and the power/energies. The nature of both the graphs is quite different in case of power it is linearly increasing with the time, whereas in case of the energies the graph is linear in nature. Also the error and accuracy is found out with a fluke data which is based on the values of fluke instruments.
