This research project focuses on the coordination of electrical protections at the Valencia Distribution Substation, located in La Nueva Unión parish of the Valencia canton. The primary issue addressed is the high incidence of short circuits in the electrical distribution networks due to factors such as tree branches, atmospheric discharges, and vandalism, which can result in power outages and equipment damage. The objective is to achieve the selection, adjustment, and coordination of electrical protections to reduce the impacts of electrical faults. This will be accomplished through a short-circuit study, the selection of protection elements, the coordination of electrical devices, and the proposal of improvements to prevent improper general power cuts and damage to the substation. The project highlights the proper management of electrical protections through a detailed short-circuit study and the identification of suitable protection devices. Effective coordination between these devices is achieved to minimize undesired disconnections. Furthermore, there is an emphasis on the need to upgrade certain components due to the increased electrical demand in the area. The results demonstrate significant improvements in the substation's operational reliability, reducing the frequency and impact of power outages and equipment damage.
