Análisis de estabilidad transitoria de ángulo y frecuencia del sistema híbrido de las íslas Galápagos Baltra-Santa Cruz.

Abstract

In the present work, the transient and frequency stability of the Interconnected System of the Galapagos Islands is studied, modeled in PowerFactory of DigSILENT, for which a review of the transient and frequency analysis is carried out. Through different load and generation scenarios, the most representative contingencies for the system and its response are simulated in a graphic way of the behavior of the rotor angle, active power, frequency and voltage delivered by the generators; that allow to observe the oscillations produced by the contingencies and if the system is stable or unstable before the disturbances. The contingencies to be simulated are the faultless exit of generator 9, a three-phase short circuit of 100ms in the Santa Cruz 35.4kV bar with disconnection of the Baltra-Santa Cruz 34.5kV line and three-phase failure of 100ms in the Baltra 13.8kV bar, are disconnection of the Baltra coupling room line, corresponding to the link with the wind plant.
