An algorithm for power system disturbance monitoring
O'Shea, Peter J. (2000) An algorithm for power system disturbance monitoring. In ICASSP '00. Proceedings. 2000 IEEE International Conference on on Acoustics, Speech, and Signal Processing, 5-9 June 2000.
This paper presents a spectral analysis algorithm for monitoring the characteristics of the damped oscillating "modes" which are set up after a disturbance in an electric power distribution system. This monitoring is necessary so that one can detect early whether any modes are "inverse damped" (i.e. exponentially growing), and hence likely to create instability in the power system. In this application it is necessary to be able to resolve modes which are very closely spaced in frequency, and which may be imbedded in substantial noise. The proposed algorithm is Fourier based, and is an extension of a method proposed by the author. The extension enables resolution of very closely spaced multiple modes and has good noise performance. The scheme is tested on simulated signals and on a real power system example
Impact and interest:
Citation counts are sourced monthly from and 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 downloads displays 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.
