Synchronized Phasor Measurements for Smart Grids — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

This chapter focuses on the introduction of synchrophasor technology and its practical use for enhancing real-time monitoring and control of the electric grid. Many real-life examples have been illustrated with the help of case studies. Realtime event analysis and low-frequency oscillation monitoring are the most basic applications of synchrophasor data which is possible with only a small number of PMUs deployed. Cause analysis of critical incidence and applying corrective action are some other areas where PMUs data is utilised for improvement of the grid performance.
