“…Based on the algorithm comparisons [11], [12], the PSFE algorithm have been selected to process the sampled data. Using simulations and studies already presented in [13], [14] and tests published in [15], [16] the algorithm error of phase estimation is expected to be less than 0.1 mrad and for amplitude estimation less than 10 μV V −1 for sampling frequency 15 MSa s −1 , records longer than 10 periods of the signal, and coherent sampling.…”

The number of Phasor Measurement Units (PMU) is growing rapidly. The metrological institutes and calibration laboratories has to calibrate not only PMUs, but also calibrators of PMUs. To achieve this goal, several reference PMU systems have been built. These systems use costly time synchronization units.The paper shows another method to trace a digitizer to a standard of time. The advantage of the method is removing a need to obtain a time synchronization unit. Setup of a reference PMU system using the method is described and uncertainty budget is shown. The budget shows out the presented method achieved sufficiently low uncertainties required for calibration of PMU calibrators.

A method for traceability to SI for ac voltage and current based on high performance digitizers is presented. In contrast to the existing thermal-based methods, the proposed method utilizes direct traceability to quantum-based waveforms via the use of Josephson voltage systems. This allows not only a simplification of the traceability chain and reduced measurement times but also offers the potential for analysis of the ac voltage and current waveform spectral content, a feature which is not possible using thermal methods. Scaling of current and voltage is achieved by the use of current shunts and resistive voltage dividers respectively. Target operating ranges are up to 1 A and 100 V with a frequency range up to 1 kHz for both. The corresponding target uncertainty for this traceability route is 1 μVV-1 and 2 μAA-1 up to frequencies of 1 kHz. The traceability chain is described and various components are characterized to validate their suitability for this task. It is demonstrated that these uncertainty targets can be met under certain conditions. The use of multi-tone calibration waveforms is investigated to further reduce measurement time. An uncertainty analysis method based on simulation using real component performance data is demonstrated.
