Power Distribution Network Topology Detection With Time-Series Signature Verification Method

Abstract

This paper proposes a novel method for topology detection in distribution networks called the Time-Series Signature Verification Method for Topology Detection (TSV-Top). The TSV-Top analyzes data from phasor measurement units (PMU or μPMU) installed on power distribution feeders. The TSVTop relies on the fact that measurement data time series from power systems contain similar trends when network topology changes occur, and basically performs the projection of actual voltage phasorial patterns onto a library of signals associated with possible topology transictions of a given distribution network. The proposed algorithm is validated using a 33-bus testbed and the IEEE 123-bus feeder, and then compared with another state-ofthe- art algorithm using the IEEE 37-bus feeder.
