A multi-resolution dataset of electrical consumption and power quality measurements from the Port of Funchal

This dataset was collected at the Port of Funchal, Madeira, comprising detailed electrical measurements obtained using a calibrated power quality analyser. The dataset includes time-series data of voltage, current, active and reactive power, harmonic distortion, and other power quality indicators, recorded at multiple sampling intervals. In addition, the dataset integrates information on vessel arrivals and characteristics, as well as weather data corresponding to the same period.
