The Way

The monitoring of power quality is the foundation and prerequisite of its improvement. There are a lot of disadvantages in the conventional method of power quality monitoring, the adoption of the virtual instrument and network technology can overcome these disadvantages very well. Remote power quality monitoring system based on LabVIEW was put forward, as well as the way of the combination of software and hardware and the realization procedure is illustrated in detail in this paper. Then the merits of this way are mentioned, and the additional functions that can be further developed. This paper provides a more convenient way for the realization of remote power quality monitoring

Intuitive Interface

With the analysis of traditional power quality monitor system, this paper introduces the system built by virtual instrument technology. From the power quality indicators and the measuring principles, we designed a data acquisition hardware based on the USB bus and developed the monitoring system applications using LabVIEW software. Comparing with conventional power quality monitoring system, the system overcomes the weaknesses of huge analog test devices. In this system, the intuitive interface makes operation simple with rapid response and small errors. In addition, statements and automatic alarm function is added to the software programming, which will be a great practical significance of the realization of automated monitoring.
