Location Method for Forced Oscillation Sources Caused by Synchronous Generators
Pablo Marchi, Pablo Gill Estevez, Cecilia Galarza
In this article, we present a new methodology to identify if forced oscillation sources are generated in excitation systems or in turbine governors. In this context, we propose to…
Non-Stationary Power System Forced Oscillation Analysis using Synchrosqueezing Transform
Pablo Gill Estevez, Pablo Marchi, Cecilia Galarza +1
Non-stationary forced oscillations (FOs) have been observed in power system operations. However, most detection methods assume that the frequency of FOs is stationary. In this pape…
A Self-Adaptive Contractive Algorithm for Enhanced Dynamic Phasor Estimation
Francisco Messina, Pablo Marchi, Leonardo Rey Vega +1
In this paper, a self-adaptive contractive (SAC) algorithm is proposed for enhanced dynamic phasor estimation in the diverse operating conditions of modern power systems. At a high…
Augmented Generator Sub-transient Model Using Dynamic Phasor Measurements
Pablo Marchi, Francisco Messina, Leonardo Rey Vega +1
In this article, we present a new model for a synchronous generator based on phasor measurement units (PMUs) data. The proposed sub-transient model allows to estimate the dynamic s…
