چکیده

The awareness of the state of the power grid, such as voltage magnitude, frequency and phasor angle is critical to maintain reliable and stable operations of the power grid. Synchronized by a common timing source, synchrophasors measure the electrical waves on power grids. The collected data are transmitted to the central server for further data processing and analysis, such as abnormal event detection and location, power flow analysis. However, the high installation fees and large form factors prevent the large-scale deployment of the synchrophasors. In this paper, a brief history and the basic principles of synchrophasors are introduced. The state-of-theart synchrophasor technologies and the smart grid protection method using Phasor Measurement Units (PMU) a member of the synchrophasor family, are presented. The application and the challenges of synchrophasor technologies are also discussed.
