Summary
This paper proposes a multi-criteria approach to evaluating PMU (Phasor Measurement Unit) data quality in real-time. This approach is based on practical experience gained from addressing various issues with field-collected PMU data. The aim is to enhance the reliability of synchrophasor data to improve operational decision-making.
Read more Read lessThe proposed methodology effectively addresses nearly all known issues related to PMU data quality in the Brazilian grid. Relying solely on quality bit filtering as defined by the IEEE
C37.118-2011 standard would still allow some outliers to "fly under the radar" some outliers, due to unforeseen reasons. The methodology adopted not only supports compliance with industry standards but also enhances user confidence in real-time applications by leveraging data exclusively from high-quality PMUs for analytics, control-room wallboard visualizations, and alarm processing.
This paper will also present statistical data on inconsistencies observed in the PMU collection.
These results, derived from several months of ongoing observations, aim to stimulate broader discussions among the users of WAMS technology to improve the management of data quality, enabling a better response from applications which use PMU data for real-time decision support.
