CIM/E模式版本管理和映射方法

随着智能电网的建设,各类智能电网信息系统呈现分布式和异构的特点,要求通过提升信息系统的互操作能力来促进智能电网信息的共享和交互。文中以提升基于电网通用模型描述规范(CIM/E)的智能电网模型信息互操作能力为目标,分析CIM/E类定义模板的构成及其对CIM/E数据的约束、CIM/E模式扩展方式,研究建立CIM/E模式版本管理及CIM/E与公共信息模型(CIM)的模式映射体系,实现了电网模型信息互操作中CIM/E模式的统一管理及面向应用的灵活扩展。通过基于实际案例的CIM/E与CIM/XML互转,验证了CIM/E模式版本管理和模式映射的有效性,保证了CIM/E模式与不断演进的CIM版本同步的能力,进一步推动了CIM/E标准的国际化推广。

CIM/E Schema of Version Management and Mapping Method

With the development of smart grids, all kinds of smart grid information systems appear to be distributed and heterogeneous, making it necessary to facilitate smart grid information sharing and interaction by enhancing the interoperability of information systems. Aimed at improving the interoperability of CIM/E based smart grid model information, the structure of CIM/E template and its constraints on data and the expansion mode of CIM/E schema are analyzed. And CIM/E schema version management as well as the mapping system between CIM/E and CIM RDF schema is established, while the control and application-oriented flexible expansion of CIM/E schema used in grid model information interoperability is achieved. The effectiveness of CIM/E schema version management and schema mapping is validated through actual mutual conversion between CIM/E and CIM/XML, the ability of synchronizing CIM/E schema with the steadily evolving CIM versions is guaranteed, and the international promotion of CIM/E standard further promoted.
