XML数据库在IEC 61850装置实时数据库中的应用

Application of XML Database in Real-time Database for IEC 61850 Devices

在分析IEC 61850信息模型的基础上,提出了使用可扩展置标语言(XML)数据库作为IEC61850装置实时数据库的方法。研究了2种实时数据库的结构,即存储当前系统信息的静态库和存储系统事件的变位库,给出了这2种库完整的XML模式定义及应用程序编程接口(API)定义,并基于此研究成果开发了完全符合IEC 61850信息模型的实时数据库,将其用于IEC 61850代理服务器。最后,通过现场检测验证了XML数据库应用于代理服务器的可行性和实用性。

Based on analysis of IEC 61850 information models, a method of using the extensible markup language （XML） database as the real-time database for IEC 61850 devices is proposed. The structures of two real-time databases are studied, i.e. the static library storing the current status information and the event library storing system events. The complete XML schema definition and application programming interface （AP1） definition of the two databases are presented. An information model fully compliant with the IEC 61850 information model is developed based on the results of the proposed real-time database, which can be applied in the IEC 61850 proxy server. Finally, the feasibility and practicability of the IEC 61850 proxy server applied XML database is proven by on-the-spot test.
