Application of synchrophasor measurements using PMU for modern power systems monitoring and control

Synchrophasor measurement technology has become a mature technology with deployment of large number of PMUs in many major power systems across the globe in last two decades. The driving force behind the innovation of PMUs is that, the occurrence of major blackouts in many power systems around the world. This paper provides a brief introduction to PMU and synchrophasor measurement technology and the applications of these measurements for improved monitoring, protection and control of power system. Also the superiority of PMU based synchrophasor technology over conventional SCADA technology is discussed. Industry is now focusing on synchrophasor-based applications for improved monitoring and control of power system, which are discussed in brief in section-IV. Some international standards governing synchrophasor measurements in power system and PMU interoperability are listed in section-V. This paper help readers to understand synchrophasor measurement technology, its superiority over conventional SCADA system and present research focus on application of synchronized measurement in improving power system reliability.
