Power quality XML markup language for enhancing the sharing of power quality data

The growing attention on power quality related problems has prompted the need to share power quality information between measurement equipments, and analysis and simulation tools. However, existing equipment designs are still very much proprietary and are rarely catered for the exchange of information between one another. Contrasting data format and communication protocol has often obstructed the sharing of information. This paper describes an attempt to exploit a well-known Internet technology, the XML, to facilitate the sharing of power quality information. Based on the well-known power quality data interchange format (PQDIF), a new power quality XML markup language is proposed. The definition of the of markup language is described in details with illustrative examples language is described in details with illustrative examples of several XML-based power quality documents. Two possible data-exchanging scenarios, including one over the Internet, are also demonstrated in the paper.
