The technology for phasor measurement of sinusoidal electrical parameters within large electrical grids has existed for some time now. The lowering of equipment costs has led to a large number of devices being installed. A lot of the potential applications of phasor data measurement for smart grid control have not yet been exploited.
A big weakness for the potential real-time applications is the reliance on the GPS satellite system, the current aim is, to establish a time synchronization system using atomic clock centers on Earth. Another concern is the cybernetic security of the currently used telecommunication lines through which the data is transferred to operator centers. Currently available solutions were developed for SCADA systems and are too slow for real-time data transfers. For the purpose of cybernetic security new hardware-based options, as well as regulating Standards are being developed.
The purpose of this paper is to construct a prototype monitoring program with the ability to detect and localize trip events in a large electrical interconnection based in the measurable electro-mechanical response of the grid itself.
