The use of advanced technologies necessitates sophisticated instrumentation for the operation, control, restoration, and protection of a rapidly expanding electricity system under normal and abnormal conditions. Currently, phasor measurement unit (PMU) applications are widely found in real-time operation, monitoring, controlling, and analysis of power system networks because it eliminates the various limitations of supervisory control and data acquisition system (SCADA) traditionally used in power systems. PMU data is becoming increasingly important for online and offline analysis. Wide area measurement system (WAMS) is a new technology developed by combining multiple PMUs in a power system. The present paper proposes a model of MATLAB based PMU using Discrete Fourier Transform (DFT) algorithm and evaluation of its operation under different contingencies for analysis of current signals magnitude and phase angles of power system. In this paper, PMU based two bus system having WAMS network is presented as a case study.
