Application of XML information exchange technology in remote-vision data transmission of power system

Power system information integration requires for the realization of open access,? data sharing and data combination among all kinds of application systems. As a standard transmission format, XML provides methods for describing structural data, has capability of data self-description and is independent of platform. These characteristics are fit for information exchange in power system. According to the current applications in power system, the isomeric data types in power automation application systems are analyzed and classified by different causes. Taking video monitoring system as example, the paper focuses on principles and methods for information exchange in power system using XML techniques. The characteristics of data modeling are firstly analyzed and the principles of data modeling are illustrated. According to practical power automation system and properties of XML, the potential applications in information exchange of power system are proposed. As a pivot, the principles of data exchange among different types of database are elaborated in detail, and then the implementation methods and examples XML are presented. Based on SQL server database and IIS server, the implement methods and application characteristics are elaborated and analyzed.
