Micro-synchrophasor data for diagnosis of transmission and distribution level events

Abstract

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 voltage magnitude and phase angle data described provides indicators for events originating at transmission or local distribution level events sensed through the LBNL network.
