Micro-Synchrophasor Data for Diagnosis of Transmission and Distribution Level Events

This paper describes the benefits of time synchronized advanced sensor data for event detection. We present measurement data collected from a network of micro-synchrophasors (µPMU) installed at Lawrence Berkeley National Laboratory (LBNL)—the first pilot network of distribution-level phasor measurement units (PMUs). The time-synchronized, high fidelity volt-age magnitude and phase angle data described provides indicators for events originating at transmission or local distribution level events sensed through the LBNL network.
