Identification Faults on Transmission Line by using Phasor Measurement Unit (PMUs)

The phenomenal growth of power system network both in terms of geographical sprawl as well as technological advancements, it requires tools for dealing with the system, wide disturbances that often cause widespread catastrophic blackouts in power system networks. When a major disturbance occurs, protection and control measures play the most important role to prevent further degradation of the system, to restore the system back to a normal state and minimize the impact of the disturbance. Continuous technological innovations in information and communication technology, novel sensors and measurement principles in general have promoted the advent of Phasor Measurement Units (PMUs). This paper describes the modelling and testing of Phasor Measurement Unit for two bus transmission line system for identification faults(like LG fault) using MATLAB/Simulink. Since PMUs are costly device therefore module wise testing and analysis are essential. For such modelling and testing, software based analysis is the best approach. This has been done through MATLAB and the results were analysed.
