Abstract [en]

Most studies of power system interarea mode oscillations focus on the analysis of slow coherent groups of synchronous machine angle and speed variables. It has not been clearly defined how the interarea modes of oscillation propagate through the power network. The purpose of this paper is to bridge this gap by studying the oscillations present in the bus voltage and frequency variables. Such knowledge would be useful for using phasor measurement data on high-voltage transmission buses. Earlier a technique has been proposed to develop an interarea model of a power transfer path using synchronized phasor data. Here the technique to obtain voltage and frequency oscillation characteristics is generalized to multi-machine power systems with multiple interarea modes.
