Abstract

The proposal of this project is to present an investigative study of the modal analysis applied to Distribution Systems (DSs) in the context of Power Quality (PQ), considering the harmonic distortions. From the harmonic resonance mode analysis, an investigative study will be conducted to indicate which bus bars will be more sensitive and observable in face of harmonic distortions. It is worth mentioning that the method of modal resonance analysis, which is based on the spectral decomposition of the admittance matrix of the electric system, already presents interesting applications focused on transmission systems. The challenge of this research will be to investigate its application to DSs focusing on harmonic distortions, as well as their monitoring. Among the expected results of the project execution is a better understanding of the problem of harmonic distortions, trying to highlight the sensitivity and observability of the DSs tests against the problem defined in the context of the PQ.
