A web-based monitoring approach for power systems in industrial plants

This article presents an Ethernet remote monitoring system for electric industrial power distributions. This system permits monitoring through the spread of low cost remote platforms, with synchronous acquisition, Ethernet communication, computational analysis programs, statistical treatment and creation of automatic reports. The dissemination of this system allows a fast and systematic approach to the harmonics disturbances problematic. It has the capability to remotely study the propagation of these disturbances in the industrial installations, to determine waveform distortion caused by harmonics sources, to quantify the impact of these disturbances and to elaborate daily quality indexes reports (IEEE Standard 519-1992) based on recent harmonics analysis techniques. This paper describes the hardware prototype of the data acquisition system architecture for power quality monitoring and analysis. The prototype was validated by statistical procedure and are presented experimental results made in real industrial plant, proving the system viability and value added in this problematic area.
