Mejora de estabilidad de voltaje a largo plazo en un sistema de 39 barras, usando los reguladores de voltajes automáticos (AVR)

Abstract

To perform an analysis within the Electrical Power Systems (EPS), it is of vital importance to consider that, in the process of generation, transmission, or distribution it is common to have several disturbances that violate the voltage stability. The present project is based on a modeling in the IEEE 39 BARS system developed in the DIgSILENT Power Factoy software, where several common scenarios will be explored where some disturbance, fault or critical points in the electrical system can be originated. The objective of the simulation will be the identification of the critical bars where an improvement is sought, highlighting the use, efficiency and advantages of automatic voltage regulators (AVR) strategically located to counteract the effects of instability. Consequently, to the evaluation of these scenarios, it will be determined how these disturbances affect voltage stability, employing the voltage stability analysis will reach the voltage levels in their operating ranges, without compromising the power supply and respecting the regulations.
