Systems and methods for synchronized phasor measurement in a power distribution network are described. In an aspect, the systems and methods quantify the phase angle between voltages or currents at any two points in the distribution network. In another aspect, the systems and methods establish a common time reference between points on a power distribution network by transmitting a synchronization pulse throughout the distribution network. In an additional aspect, the systems and methods extract phasors from a power line waveform by utilizing a phase-locked loop (PLL) and regression of the zero-crossings of the PLL output waveform.
