Power System Oscillation analysis

Started by Bessie September 1, 2007
What other methods can be used to analyse power system oscillations from
phasor measurements besides FFT and Wavelet?

Your phasors rotate at f=50 or 60 Hz? You could downconvert them to 0 Hz by
multipliying with exp(-i 2 pi f t) and lowpass filter.
In the complex plane you can then see how frequency behaves (1 forward
rotation per second: Frequency is 1 Hz too high etc).
