Abstract :
The generation mix, flexible ac transmission (FACTS) devices, changing loads, and limited transmission paths have combined to reduce the accuracy of existing system models. This degradation in accuracy has come at the same time that improved models are needed to cope with increased stress on the bulk power system. This paper demonstrates the use of synchrophasor data in displaying and analyzing system events in order to update and improve system and generator models. Examples are given of actual events captured using wide-area and local synchrophasor measurements. Comparison of the data analysis capabilities of streaming synchrophasors to traditional supervisory control and data acquisition (SCADA) is presented.
