XML Description Schema for Power Quality Data

The recent growth in the number of permanently installed power quality analysers has led to an increase in the amount of data requiring central processing. The information contained in the voltage and current waveforms is progressively transformed into knowledge enabling improved operation of power utilities. This power quality data chain requires a data organisation that facilitates this transformation process occurring at several locations as well as on a range of computing platforms. This paper proposes a XML schema that is both compatible with this process as well as with the standards related to power quality.
