EVALUATE REAL TIME VOLTAGE STABILITY USING WIDE AREA MONITORING SYSTEM

Abstract

The rapid development of power system, both in terms of scale as well as
technological advances, requires tools to deal with systemic disruptions that
cause overload on transmision lines, dragging down the voltage collapse and
power system disruption for many years. When major disturbances occur,
protection and control solutions play the most important role in preventing
system collapse, restoring the system to normal and minimizing the impact of
incident. New improvements in science, technology, information and
communications, sensor technologyand the emergence of large-scalehave
spurredapprearance of wide area monitoring system using phasormeasurement
unit. This article describes the simulation of this device and method of evaluating
real-time voltage stability. Simulation results are analyzed, evaluated on IEEE 39
bus system using Matlab /Simulink.
