Initial Applications of Synchrophasors Using Area Angles

Abstract

Synchrophasors allow fast, synchronized measurements of the power grid and have the potential to serve power system applications more e ectively. Synchrophasor data may allow analyzing subareas of the system without need for access to outer area information. This thesis focuses on implementing the area angle concept on subareas of networks for various power system tasks. First, we show the ability to decouple a subnetwork using only the area's synchrophasor measurements and superposition. Next we present a line outage detection algorithm within an area for both islanding and non-islanding cases. Finally, we discuss de ning area angles for meaningful analysis of a power system,particularly for areas in the WECC system.
