Mejoras del ángulo de apantallamiento y del sistema de puesta a tierra de pie de torre en líneas de subtransmisión de 69 KV

Abstract

The central purpose of this project is to optimize the shielding angle and the grounding system of the towers on the 69 kV sub-transmission lines. This approach seeks to prevent the disconnection of lines caused by atmospheric discharges, since throughout the year there have been numerous cases of feeders being out of service. The resolution of these situations involves the implementation of preventive corrections, thus guaranteeing the optimal operation of the system. In this context, an exhaustive analysis of the section of a sub-transmission line that experienced multiple interruptions during the year due to atmospheric discharges was carried out. The fundamental objective was to ensure the long-term stability of the system and mitigate the occurrence of similar events in the future. This analysis focused on the detailed study of the shielding and grounding system, which enabled the precise design and sizing of the essential elements in the system. As the final phase of the project, extensive testing was performed using ATP-DRAW software. The purpose of these tests was to verify that the line reduces disconnections, thus ensuring its correct and efficient operation.
