Abstract
Distribution phasor measurement units (DPMUs) provide power grid operators unprecedented system monitoring opportunities with local-area, synchronized, low latency, and high-resolution measurements. All raw angle measurements in DPMUs require a common angle reference for comparison since the phase is likely to be shifted by transformers in distribution network. To obtain a robust reference under conditions of data loss or local oscillation, this letter proposes a definition of system angle reference for DPMU. The effectiveness of this system angle is validated via real measurement data collected by DPMUs.
