公共信息模型的 OPC UA 地址空间管理

摘要

The international electrical commission ( IEC) energy management system application program interface ( EMS‐API) is a standard to encourage the integration between power enterprise applications . Since the component interface specification ( CIS) of EMS‐API standard has been upgraded to object linking and embedding for process control ( OPC) unified architecture ( UA) technology , this paper studies the problem to manage the common information model (CIM ) data by using the OPC UA address space model . The mapping rules from the CIM data to the OPC UA address space model , the rules of mapping the identifier and name of the UA node to CIM instances , and the process method of relationship in CIM data , are proposed . Subsequently , based on the UA Stack library developed by the OPC foundation , the CIM data OPC UA server is realized and verified in practice .%国际电工委员会（IEC）能量管理系统接口（EMS‐API），是为了促进电力企业应用间的集成而制定的标准。针对 EMS‐API 标准的组件接口规范（CIS）升级为采用过程控制对象链接与嵌入（OPC）统一架构（OPC UA）技术这一改变，就如何使用 OPC UA 对电力公共信息模型（CIM ）进行管理，提出了 CIM 到 OPC UA 地址空间模型的映射规则、CIM 对应 UA 节点的标识、命名以及关联关系的处理方法；基于 OPC 基金会开发的 UA Stack 库，研究实现了 CIM 的 OPC UA 服务器，并对研究结果进行了实际验证。
