Determine Disturbance Locations in Power Grids using Bicubic 2D Interpolation on Electromechanical Wave-front Propagation Delay

Abstract

This study presents a method to locate power system disturbance using wide-area synchrophasor measurements. The merits of the proposed method include robustness and easy for visualization. In addition, the proposed method facilitates the calculation of electromechanical wave propagation speed distribution. An example of locating the disturbance and generating the propagation speed distribution is demonstrated based on FNET/GridEye, a distribution-level wide-area measurement system. Without losing generality, the proposed method can be implemented in any other wide-area measurement systems.
