基于CIM和OPC统一架构的配用电网数据平台研究

以公共信息模型和OPC统一架构为基础,研究了支撑综合数据分析的配用电网数据管控平台构建,包括系统架构和信息模型研究、数据管理、服务体系构建及数据汇集等。分析配电、用电领域业务系统数据,裁制IEC TC57公共信息模型并扩展补充,形成配用电数据统一信息模型。建立信息模型及对象数据到OPC统一架构信息模型的映射规则,在OPC统一架构地址空间中对经规范化汇集整合的多个配用电业务系统的数据进行管理。实现OPC UA统一架构服务,为分析应用提供安全高效的数据访问支持。配用电网数据平台与业务系统、综合分析应用有机地协同在一起,在工程中得到实践。

Research on data platform for power distribution and utilization based on CIM and OPC UA

On the basis of the common information model and the OPC unified architecture, this paper studies the construction of distribution and utilization grid data platform to support comprehensive data analysis, including system architecture and information model research, data management, service system construction, and data aggregation. A unified information model is formed through analyzing the data in each distribution and utilization business system, tailoring the IEC TC57 common information model accordingly, and supplementing undefined elements in the CIM. The mapping rules of information model and object data to the OPC unified architecture information model are established. After the data of distribution grid and utilization system from multiple business systems have been standardized and aggregated according to the unified information model, all schema and object data are managed in the OPC unified architecture address space. Services defined by the OPC unified architecture are implemented to provide secure and efficient data access support for analysis applications. The data platform is organically coordinated with the business systems and comprehensive analysis applications, and its technical scheme has been put into practice in engineering.
