This paper presents an efficient methodology for estimating the damping of a power system in which multiple resonant frequency components exist. The proposed method was developed using the analytic wavelet transforms and requires only the intrinsic transient portion of the voltage waveform (i.e., the free response due to capacitor bank energizing). The method can estimate the damping ratios of the selected modes and is free from the unimodal restriction of the Hilbert damping analysis. Thus, the method can provide more accurate system modal information.
