“…The combined standard uncertainty of the calculated total harmonic current values can be determined by the combined standard uncertainties of the rms values of the individual harmonics [19]. If one harmonic magnitude dominates the THC, its uncertainty corresponds approximately to the individual uncertainty of the respective harmonic.…”

This paper presents the results of comprehensive testing, and subsequent detailed analysis of obtained test results, evaluating harmonic and interharmonic performance of PV inverters (PVInvs) for a range of different operating conditions. The presented results indicate significant power-dependent changes in harmonic and interharmonic emissions of tested PVInvs for different supply voltage conditions (presence of voltage waveform distortions and various source impedance values). To correctly quantify and describe these changes inPVInvs' performance, the paper discusses and applies measurement procedures and metrics for evaluating harmonic and interharmonic emission recommended in existing standards, as well as some additional metrics and indicators. For some operating conditions, tested PVInvs significantly increase both harmonic and interharmonic emission, and paper also discusses impact of PVInvs' controls (e.g. maximum power point tracking control) as a possible origin of the interharmonic distortion.

The paper deals with modeling and estimation of uncertainty in measurement of power quality (PQ) characteristics by using a virtual measurement instrument. The described virtual PQ analyzer is comprised of National Instruments (NI) analog input modules, NI data acquisition board, personal computer and software in LabVIEW™. The main sources of uncertainty are identified and evaluated. A Monte Carlo simulation is used for the model estimation and generation of the combined uncertainty of particular characteristics. Experimental measurement and statistical analysis of the results are made and compared with the simulation results. The experimental results have served for a verification of the model and the Monte Carlo simulation results.
