A Statistical Investigation of PMU Errors in Current Measurements
2023 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2023 Phasor Measurement Units (PMUs) are becoming widespread in power systems monitoring. Applications relying on synchrophasor measurements ask for models of measurement er-rors that can be integrated to describe the uncertainty of the data. In this paper, an assessment of PMU magnitude and phase-angle errors for current measurements is performed for the ...
