Wide area frequency based generation trip event location estimation

This paper presents the latest development in wide-area frequency-based generation trip event location. Real-time generation trip location information is very useful to system operators and also to power producers. Using synchronized frequency data from wide-area frequency monitoring network (FNET) as input, the event location estimation is expressed as nonlinear optimization problem. In this paper, we address a systematic way of dealing with coordinates conversion issue in solving this problem. The coordinates of event location, the time at which event occurred, and the propagating speed of the electromechanical wave, are solved simultaneously using Gauss-Newton method. The presented computation process is concise and efficient. Using actual event data, the proposed procedure is examined for implementation feasibility.
