Damping Estimation in Highly Interconnected Power Systems
Glickman, Mark, O'Shea, Peter J., & Ledwich, Gerard F. (2005) Damping Estimation in Highly Interconnected Power Systems. In IEEE TENCON '05, 21-24 November 2005, Crown Promenade Hotel, Melbourne, Australia.
In a large interconnected power system, oscillating modes typically arise after disturbances. Estimation of the rate of rise or decay of these disturbances (i.e. of the damping factor) is important so that poorly damped modes which put the system at risk can be identified. In the past both Fourier based and parametric techniques have been used to estimate the damping factors of the oscillating modes. Parametric methods tend to perform poorly in noise and existing sliding window methods do not optimally account for the kind of noise present in real operating environments. This paper presents an improvement to existing Fourier based methods for damping factor estimation. Simulations and real data results are provided to support the claims made in the paper. A comparison with parametric methods is also made.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
