摘要
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。
The source servicing in the smart substation offers the base for the model integration between the substation and the main substation.The IEC 61850 Ed.2 provides the base for conversion and share of the information model between the substation and the main substation.The description form,the structure,the function and the characteristics of the SSD（system specification description） model in IEC 61850 Ed.2 and the CIM（common information model） model in IEC 61970 are analyzed.In addition,the difference and characteristics between SSD model and CIM model are compared.As a result,the mapping relation and the common ground are obtained.Furthermore,the conversion technology between SSD model and CIM model is realized,which provides forceful guarantee for data consistency at dispatch centers in source servicing of unified information platform of smart substation,and for the information share between the substation and the main substation.
