Synchrophasor based real time monitoring of grid events in Indian power system

The availability of Synchrophasors has considerably enhanced the wide area visualization and situational awareness of power system behaviour under steady state as well in transient/dynamic conditions. The availability of Synchrophasor data at control center has become first-hand information for grid operator to view and analyze any transient phenomenon occurring in the grid. Various events that went unnoticed with Supervisory Control and Data Acquisition (SCADA) system are now being detected and analyzed, opening up a completely new era in power system monitoring and control. There is a paradigm shift in monitoring the grid after the commissioning of Synchrophasor projects. Now-a-days control centre operator first observes the signature of events through PMUs data and then refers to SCADA system for the details of the events. Since the commissioning of Synchrophasor pilot projects in India, the synchrophasor data available at the Regional & National Load Despatch Centre has been utilized for real time visualization and also for post-dispatch analysis in offline mode.
