Design Of Power Quality Monitoring System Based On Virtual Instruments And Database Technology

According to the virtual instrument technology, the database technology and the national standard, a power quality monitoring system with a distributed structure, is proposed. In this system, with the model of client and server, the data of the important circuit are collected and processed, so as to obtain the monitoring standards of all the power quality. After determining the overall system design, focus on the development system using LabVIEW models. Basing on theoretical research, this paper designed the power quality monitoring system with the industrial computer and data acquisition card system. Compared with the previous design, the power quality monitoring system has real time, high performance, scalability and other advantages, and is in line with the latest power quality monitoring development requirements.
