Modern Techniques for Power Quality Analysis Using LabVIEW Environment
Le résumé fourni par la source
This paper presents a case study for monitoring the quality of electric energy in an industrial manufacturer of technical rubber and reclaimed rubber products. The measurements were carried in the power supply point where the quality of the electric energy is influenced by the activity of the manufacturer, the transmission and distribution provider, the supplier as well as the electric power consumer activity. Transients occur at this limiting point, with negative effects on the consumer, as well as on the electric power supply network. Quality indicators of electric energy, depending on the place of occurrence of disturbances are indicators of primary and secondary quality indicators. The data processing was achieved using LabVIEW software in terms of the two types of quality indicators. A software application was made to allow reading of files and processing them (creation of data tables and charts). Based on the data obtained from the measurements and using the interface created in LabVIEW, it was possible to carry out the analysis of the average hourly consumption, the power factor, the wave forms of the current and voltage, the analysis of the current and voltage harmonics. The software application enables creation of customized reports with varying ease of use and flexibility. Using the software application developed in LabVIEW, full quality analysis of electric energy can be done at the user's premises.
