A synchrophasor measurement based method for assessing damping torque contributions from power system stabilizers

A conference paper that I’ve worked on as part of my PhD research has finally been published, so I shared it here for all you power systems aficionados out there. The paper is about a new method for assessing the damping torque contributions from power system stabilizers. If you understand every word in the title, then it’ll be of interest to you. If not… well it might be interesting too. Anyways, this papers was presented at the IEEE PowerTech 2015 conference in Eindhoven, the Netherlands in July. I didn’t get to go to the Netherlands for the conference, but at least I have another entry in my (short and unremarkable) publications list. Read below for the abstract and link to the full paper.

A synchrophasor measurement based method for assessing damping torque contributions from power system stabilizers

By X. T. Jiang, J. H. Chow, and F. Wilches-Bernal

Abstract

This paper proposes a method for assessing the damping torque contribution of generators equipped with power system stabilizers (PSSs) using synchrophasor measurements from disturbance events exhibiting lightly damping oscillations. The method is based on an extension to the Heffron-Phillips and deMello-Concordia synchronizing and damping torque analysis method to include the sensitivities for the terminal bus voltage angle. It requires only examining the phase relationship between the oscillatory components of the generator rotor angle and its terminal bus voltage angle. The method can also be applied to time responses from simulation programs.
