A method of detecting the time of arrival for an electromechanical wave in large power systems

This paper deals with the phenomenon of electromechancial wave propagation in large power systems and determining the location of a fault by taking advantage of the Wide Area Measurement System and Phasor Measurement Units. Such an application requires very comprehensive and detailed research. However, in order to solve a complex problem, one must first solve several sub-problems. A proposal for the solution of one such problem is presented in this paper. A new detection mechanism for detecting the arrival of an electromechanical wave is given that uses characteristic points on a wave in a manner which is independent of the wave amplitude and its frequency. The results look promising and indicate that this issue should be investigated further in the future.
