Empirical Wavelet Transform Based Method for Identification and Analysis of Sub-synchronous Oscillation Modes Using PMU Data

Autor: Joice G. Philip, Jaesung Jung, Ahmet Onen

Publikováno v: Journal of Modern Power Systems and Clean Energy, Vol 12, Iss 1, Pp 34-40 (2024)

This paper proposes an empirical wavelet transform (EWT) based method for identification and analysis of sub-synchronous oscillation (SSO) modes in the power system using phasor measurement unit (PMU) data. The phasors from PMUs are preprocessed to c
