Disparo controlado de líneas de transmisión para mantener la estabilidad en el SEP con la implementación de FACTS.

Abstract

CONDITION FOR PUBLICATION OF PROJECT. loss of a transmission line can generate an imbalance in the system, as it leads to a redistribution of power flow. Although the power system must be designed to withstand such contingencies, in a double-circuit transmission system, the backup line is sized to support the full load that previously flowed through both lines equally, until the line that tripped due to a fault is restored. However, the EPS is not exempt from this situation; the overload taken on by the backup line may be so high that it causes its own tripping, triggering cascading effects and driving the system to critical stability levels, even to a blackout. In such cases, line protections operate within very short timeframes, and with the support of an SVC, whose injection of reactive power helps level the voltage profiles at the buses and increase the loadability of the lines, an additional time window is gained that facilitates decision-making to keep the power system operational. In future work, it is proposed to apply a systematic protection scheme based on load shedding, in order to maintain system stability and prevent collapse, considering priority criteria to determine which loads should be preserved, such as hospitals, laboratories, and others.
