Fuerzas electromagnéticas en conductores rígidos de subestaciones. Aplicación a la subestación Pascuales del SNI

Abstract

The electromagnetic forces present in rigid conductors of substation are due to high short-circuit currents, which generate stresses in the conductors and structures. In order to avoid damage to the conductors and structures, the calculation of electromagnetic forces is carried out on rigid conductors of substation based on the standard IEC 60865-1 “Short-circuit current- Calculation of Effects- Part 1: Definitions and calculation methods”. Using the MatLab software, the FUELECTRIG program is developed to calculate the forces generated in both conductors and support structures, using a simplified and detailed method with or without automatic reconnection. Finally, the application of the program in the conductors of the Pascuales substation is carried out to verify its correct operation.
