Abstract: With the rapid development of new technologies this paper shows the growth of power system both in terms of geographical as well as technological advancement, it requires monitoring tools for dealing with system wide disturbances that may cause widespread blackouts in power system networks. Protective measures play a vital role to prevent further degradation of the system, restore the system back to the normal state, when major fault or disturbances occurs. The next evolutionary step in control centre technology may be the utilization of various kinds of sensors with digital concept and measurement instrument principle in general have promoted the advent of Phasor Measurement Unit [PMU].This paper discusses about the modelling and testing of phasor measurement units with the help of wide area monitoring protection and control using phasor measurement model. This model has been done through MATLAB/SIMULINK and the results are analyzed.
