POWER QUALITY MONITORING USING LabVIEW

Abstract

With the proliferation of electronic loads and the increased competition in deregulated electric utility industry and due to rapid growth of nonlinear loads as well as interconnectedness in power system, power quality monitoring has become increasingly important. It has become an essential tool for improvements in the availability of power, for preventive and predictive maintenance, for ensuring equipment performance, and for sensitivity assessment of process equipments to several disturbances. In the present study, graphical programming of LabVIEW software has been utilized to develop power quality analyzer and also to monitor power quality disturbances (like voltage sag, swell, interruption, frequency variation, etc.) using ADVANTECH DAQ Card (inserted in PC). Use of virtual instrumentation for the measurement and monitoring power system improves the performance and reliability of the system. Monitoring helps to identify power quality problems and minimize losses in the production p...
