In this paper, we utilize fundamental concepts of time-frequency analysis to analyze transient disturbance signals in power systems. Within the restriction of the uncertainty principle, timefrequency analysis provides localized information of the disturbance signal as a function of time and frequency. Using simulation and actual power disturbance data, we show that the so-called reduced interference distribution (RID) appears to be most suitable for investigating the time-frequency characteristics of power disturbances. In this paper, the potential assessment of power quality via application of timefrequency analysis is also briefly discussed.
