Simulación de un esquema de alivio de carga considerando el efecto de amortiguamiento de carga

Abstract

This document shows the development of a protection system through the use of the methodology or calculation of the ROCOF (Rate of change of frequency) to achieve an adaptive load shedding that allows an accelerated system frequency recovery preventing possible failures in various System stages lead to the collapse of the system, for this purpose, specialized software is used in power systems called DIgSILENT PowerFactory for the simulation of failure events and analysis of all the important parameters of a transmission network, the results are compared between those scenarios in which the protection system is disconnected and those in which the system is already in operation under different types of failure and adverse conditions. The protection system is tested in a 14-bar IEEE type system obtaining improvements in the final frequency value milliseconds or seconds after the failure event, the frequency variation also finds points at which it causes the frequency to fall less quickly and At the same time, it allows to approach nominal values more quickly against non-adaptive schemes.
