网络化的电能质量综合监测系统的研究

Research of the networked integrated monitoring system for power quality

为了弥补传统电能测量仪器功能单一、存储容量小,无法进行网络化监测等缺点,系统利用了虚拟仪器技术在图形化集成开发环境,信号处理分析和网络通讯方面的巨大优势,实现了对电能质量五项稳态指标的监测,而且系统具有很好的人机交互界面,提出了利用LabSQL模块和数据库技术实现远程数据存储以及基于B/W模式和Remote Panels技术的信息发布方案,使得用户可以通过Internet直接查看即时和历史电能质量数据,实现信息共享。对本系统进行了实验室调试,试验结果表明该系统能较好地满足实际测量的需要,并且具有良好的效果。

This system makes use of the great advantages of LabVIEW virtual instrument technology in graphical develop environment, signal analysis and network communication. It could satisfy the requirement of monitoring five steady targets for power quality and have lively man-machine interface. This paper proposes the mode of the remote data storage based on the LabSQL module and database technology and the information publishing scheme based on the B/S mode and Remote Panels technology. User can inquire the data of power quality through internet. This system can make up the disadvantages of the traditional measuring instrument. The experiment results show that it can satisfy the practical requirement by debugging.
