127. Research on Power Quality Data Transfer Format Based on XML in Power Quality

Strength, compatibility, economy and interactivity are the main developmental features of Smart Grid in China. Aiming at the data exchange and sharing problem, Extensible Markup Language (XML) are introduced based on the research of Power Quality Data Transfer Format (PQDIF) in power quality management system. To study this research deeply, PQD files are transformed into XML files to solve these issues, and it describes the elaborate notes and attributes of XML files. In addition, now taking mass data needed to be stored into account, two open data compression methods will also be introduced below. The generated XML files have superiority on scalability, readability, compression and other aspects absolutely, which will be used widely in power quality data monitoring system.
