Abstract

Summary: A new Wide‐Area Monitoring System (WAMS) application for monitoring inter‐area oscillations, based on the Newton‐type algorithm is presented in this paper. The core of this novel WAMS application is a numerical algorithm for the real‐time estimation of the dominant inter‐area oscillation mode, which processes Global Positioning System synchronized information obtained from Phasor Measurement Units installed in the power system. The parameter model is a highly nonlinear function, making this a particularly difficult challenge. Two data sets were tested using the new algorithm, one based on simulated models and the other based on real‐life data records. The computer simulated model was based on a known architecture with signals obtained using a dynamic simulation of a multi‐machine power system. The real‐life data records used information collected on the FlexNet Wide‐Area Monitoring System (FlexNET‐WAMS) installed in the Great Britain power grid. Copyright © 2016 John Wiley & Sons, Ltd.
