Análisis y simulación de cortocircuito mediante componentes simétricas en un sistema de potencia con transformadores en paralelo conforme a la normativa IEC 60909-4

This study analyzes and simulates the behavior of a power system with parallel transformers under electrical faults, using symmetrical component decomposition and complying with the guidelines of IEC 60909-4. This analysis is essential to ensure the safety, stability, and reliability of electrical systems, as it allows the calculation of short-circuit currents under different conditions, providing a foundation for the proper design of protection systems and the selection of equipment capable of withstanding such faults. Symmetrical component decomposition simplifies the analysis of unbalanced systems by representing them as combinations of balanced components (positive, negative, and zero sequences). This approach facilitates the identification of causes, the assessment of fault effects, and the resolution of issues related to short-circuit currents, minimizing risks and ensuring the proper operation of the system. In systems with parallel transformers, short-circuit analysis is more complex due to the interactions between the transformers. These interactions affect both the magnitude and distribution of fault currents, depending on characteristics such as impedance, rated power, and connection configurations (e.g., star, delta, etc.). Therefore, a detailed analysis that considers differences in transformer responses and their cross-effects on the network is essential.
