Controlled separation of islands based on synchrophasors. Case study for the system Argentine high voltage interconnected

Abstract

Due to technological evolution new monitoring systems for electrical power grids have appeared. A device which is spreading all
over the world – including Argentina – is known as PMU (Phasor Measurement Unit) thanks to its synchronizing system, which
enable precise microsecond-scale measurements. e goal of this work is to analyse the application of synchrophasor technology
in controlled islanding schemes, which is a last resort for reduction of perturbation impact or major cascading failures on power
systems that can end in system collapse or blackout. e methodology used was based upon multiple simulation studies of a real
cascading failure occurred on the argentine power system. e results show that system islanding separation in the terms of this
study could be effectively implemented in order to reduce impact of major failures.
