The frequency stability assessment of the transmission system using phasor measurement unit data

The main object of this paper is the determination of the Change of Frequency (COF) which is used to assess the system stability through the advanced measurement technology of Phasor Measurement Units (PMUs). The stability of the transmission system is investigated using the operation characteristics of power lines and frequency oscillations. The results are tested in modeling the IEEE 14 bus system by MATLAB/SIMULINK.
