Query: Event Detection and Localization in Distribution Grids with Phasor
  Measurement Units   The recent introduction of synchrophasor technology into power distribution
systems has given impetus to various monitoring, diagnostic, and control
applications, such as system identification and event detection, which are
crucial for restoring service, preventing outages, and managing equipment
health. Drawing on the existing framework for inferring topology and
admittances of a power network from voltage and current phasor measurements,
this paper proposes an online algorithm for event detection and localization in
unbalanced three-phase distribution systems. Using a convex relaxation and a
matrix partitioning technique, the proposed algorithm is capable of identifying
topology changes and attributing them to specific categories of events. The
performance of this algorithm is evaluated on a standard test distribution
feeder with synthesized loads, and it is shown that a tripped line can be
detected and localized in an accurate and timely fashion, highlighting its
potential for real-world applications.
