碩士 === 中原大學 === 電機工程研究所 === 91 === The purpose of power system monitoring is to transmit the measurements through communication network for analysis. Most of the modern instruments provide some fundamental communication facility for local access. Instead of using tradition dynamic data exchange (DDE), OPC(OLE for process control) is applied for data acquisition, transmit and storage in the thesis. In the remote site, LabVIEW is used as OPC server which provides raw data. In the local site, Wonderware InTouch is uses as Man-Machine Interface (MMI). Both applications provide graphical User Interface for ease of use. The key purpose of this thesis is to transmit large amount of real-time waveform information from remote sites to a local site for storage and analysis. Because of using OPC, a large number of remote sites can be installed, information can be transmitted to the control center for system wide analysis.
