چکیده
This paper presents a review of the Phasor Measurement Units employed in the Modern Power Systems. Synchronized phasor measurements have advanced the power system monitoring, controlling, protecting and operating standards in the recent decades. Its potential can be used effectively in the process of upgrading the current power grids into smart grids. With these ideas in mind, a review on PMU is presented here describing PMU’s historical development, working principle, applications along with a brief note on optimal placement techniques. As all the potentials of PMUs are discussed in this review, it may serve people working in the field of smart grid. Keywords— Phasor measurement unit (PMU), Symmetrical component distance relay (SCDR), Global positioning system (GPS), Anti-aliasing filter (AAF), Phase locked oscillator (PLO), Symmetrical Component Discrete Fourier Transform (SCDFT).
