Análisis de estabilidad transitoria en un sistema industrial con generación propia interconectado con el sistema de potencia

Abstract

This article presents a transient stability study of an industrial process that includes an electricity cogeneration plant connected to an external central line. Problems that may occur due to disconnection from the external network are evaluated and faults such as loss of synchronism and frequency decline of the generation system are discussed. Also, possible solutions for a reliable and safety operation of the system, including load shedding and protections fitting, are discussed. This work shows that transient stability studies allow introducing corrective actions, defining criteria to establish priority of charges and observing the general behavior of the systems when problems occur. Also, it is possible to verify the corrective actions, guaranteeing the continuity of the electrical service in the plant and in its productive process.
