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