Resumen (en_US)

Sensitivity analysis of a power system against overvoltage was performed. The analysis took into account the origin of the overvoltage, the grounding resistance magnitude and overvoltage injection point. The IEEE 13 bus test feeder system was implemented in EMTP-ATP and lightning and switching overvoltages were applied. Three cases were evaluated: the first one, applying lightning overvoltage and varying the grounding resistance magnitude; the second, applying lightning overvoltage in different points of the system with a fixed grounding resistance magnitude; and finally, applying switching overvoltage and varying the grounding resistance magnitude.

Resumen (es_ES)


Se realizó un análisis de sensibilidad de un sistema de potencia contra sobretensión. El análisis tuvo en cuenta el origen de la sobretensión, la magnitud de la resistencia de puesta a tierra y el punto de inyección de sobretensión. El sistema de alimentación de prueba de bus IEEE 13 se implementó en EMTP-ATP y se aplicaron sobretensiones de sobretensión y de sobretensión. Se evaluaron tres casos: el primero, aplicando sobretensión de rayo y variando la magnitud de la resistencia a tierra; el segundo, aplicar sobretensión de rayo en diferentes puntos del sistema con una magnitud de resistencia a tierra fija; y finalmente, aplicar sobretensión de conmutación y variar la magnitud de la resistencia de puesta a tierra.
