Identification of power system topology from synchrophasor data

Abstract

With the growing prevalence of phasor measurement units (PMUs), an abundance of high-resolution data is becoming available for analysis. The problem arises of how to use the data to obtain information about the operating conditions of the system. We examine the use of data from PMUs to expose information about the underlying system topology. An equivalent network at the PMU buses is obtained. Changes in the equivalent line flows can also be mapped back to events in the full system if the normal system structure is known.
