摘要：
This remote monitoring system of power network was developed by using the virtual instrument technology, network technology and database technology. The basic structure of the system is Browser/Server mode. Through Internet Explorer, remote client can browse the real-time monitoring data of power network; such as frequency; power factor, virtual value of voltage and current, etc. In the system, the wavelet transform was applied to virtual instrument by using the MATLAB script node in LabVIEW, and utilizes denoising method of sqtwolog soft threshold to eliminate the high-frequency noise. The remote storage and query for a large quantity of data in power network monitoring was realized by using ADO in LabVIEW. remote panel technology built-in LabVIEW 7 Express was applied to satisfy the real-time data display of remote monitoring.
