A single-phase Phasor Measurement Unit for smart distribution systems

The Phasor Measurement Unit(PMU) is used for accurate measurement of synchronous phasor of voltages and currents at separated points across the power grid and are widely installed at the transmission level. As the next point of setup in smart grid, PMU is necessary for components control, fault detection and control, energy management in distribution network. This paper first illustrates the architecture of PMU setup that has been fully designed by the authors and then describes the challenge of designing and implementing which integrates field measurements to deliver Global Positioning System (GPS) synchronized phasor data to the distribution networks. By using this platform, our efforts have provided the real-time data detected, power quality analysis and direction to future efforts to analyze data in cloud calculation, harmonic state estimation, etc.
