Estudio técnico para la determinación de la ubicación óptima de unidades de medición fasorial (PMU) en el Sistema Nacional Interconectado S.N.I. basado en criterios de observabilidad ante contingencias

Abstract

Phasor measurement units PMU are measuring devices that estimate Synchrophasor of sinusoidal waves of current and voltage in electrical power systems. In the first chapter of this project, describes the characteristics of phasor measurement units, including its structure and applications. In the next chapter different methodologies that allow the location of PMUs are analized and is selected an algorithm to maintain an adequate level of visibility in a SEP. Then is deepened on voltage stability in power systems and different methods with their respective algorithms are described. Using the Reactive Support Index contingency ranking is determined by the National Interconnected System S.N.I. Finally is applied a methodology location of PMUs that minimizes the number and keep the observability of S.N.I in the failures more gravity determined based on the RSI algorithm.
