Diseño y construcción de un sistema de compensación reactiva para reducción del consumo de combustible diésel en la generación térmica de la Isla San Cristóbal Galápagos.

Abstract

The generation system on San Cristóbal Island is a hybrid system composed of thermal and wind generators. The objective was to reduce diesel consumption from two well-defined actions, the first involves the automation of the current SCADA and control systems to improve the joint operation between thermal engines and wind turbines, based mainly on an energy analysis that optimizes the control of active and reactive power; The second action was the construction of a system of compensation of reactive energy that allows to compensate the imbalances of reactive energy caused by the variations of the wind, as well as to compensate the thermal generators so that their reactive power is zero. A first stage evaluates the current situation of the generation system, selecting the best technological option to be applied in the generation system. A second stage involves all the necessary calculations for the design of the chosen compensation system and the construction of the system was carried out, adapting it to the current generation system. Finally, operational tests were carried out on the generation system of the island, measurements were obtained in the field and the results were analyzed.
