智能变电站源端维护使得实现变电站与主站间信息模型共享成为可能。IEC 61850 Ed.2的推出,为变电站和主站信息模型的转换和共享技术的实现提供了重要标准依据。研究IEC 61850 Ed.2中的变电站规范模型文件(systemspecification description,SSD)和IEC 61970的公共信息模型(common,information model,CIM)文件的描述形式、结构、功能和特性,对比分析2种模型文件的异同和特性,探讨2种模型间的映射关系。研究并实现了SSD模型与CIM模型间的转换技术。这一转换技术对智能变电站一体化信息平台源端维护中实现调度端数据一致性、变电站与主站信息互动采用统一数据共享渠道提供了有利的保障。
Source maintenance of intelligent substation makes it possible to share information model between substation and main station. The introduction of IEC 61850 Ed.2 provides an important standard for the conversion and sharing of information models in substations and master stations. The description forms, structures, functions and features of IEC 61850 Ed.2 file system specification (SSD) and IEC 61970 common information model (CIM) are studied, and two kinds of model files Similarities and differences and characteristics of the two models to explore the relationship between the mapping. Research and implementation of the conversion between SSD model and CIM model. This conversion technology provides an effective guarantee for data consistency at dispatch end in source maintenance of integrated information platform of intelligent substation and uniform data sharing channel for information interaction between substation and master station.
