Wiltshire, Richard A., Ledwich, Gerard F., & O’Shea, Peter J. (2007) A Kalman Filtering Approach to Rapidly Detecting Modal Changes in Power Systems. IEEE Transactions on Power Systems, 22(4), pp. 1698-1706.

This paper applies Kalman filtering techniques to the problem of detecting modal changes in large interconnected power systems. Short term alarming procedures are developed based on the statistics of the power spectral density of the Kalman filter innovation. The new technique is tested on both simulated data and real data obtained from power systems in normal operation. The particular advantage of the new method is its ability to detect changes very quickly.

Citation counts are sourced monthly from Scopus and Web of Science® 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.
