智能变电站信息模型的讨论

信息模型是IEC 61850标准的核心,也是智能变电站发展建设的基础。对智能变电站当前信息模型的应用现状进行了总结,分别从模型的缺失、模型的扩展和模型的一致性测试3个方面进行了讨论;对当前智能变电站建设中存在的信息模型缺乏定义的问题进行了阐述,分别从辅助设备、电能质量和稳定控制3个方面进行分析;对智能变电站信息模型的应用进行了展望,分别从IEC 61850第2版应用、IEC 61850和IEC 61970模型的协调以及功能模型应用3个方面进行了论述。文中讨论为智能变电站今后的发展建设提供了参考。

Discussion on Smart Substation Information Model

Information model is the kernel part of IEC 61850 standard and the foundation of the smart substation development and construction.The application status of information model of smart substation is summarized and discussed in three aspects,namely,the deletion of model,the extension of model and the conformance test of model.Also,the problems caused by lack of united information model existing in smart substation construction is described in three aspects such as: auxiliary device,power quality and stability control.The application prospect of the information model in smart substation is shown in three aspects such as: application of the IEC 61850 Ed2.0 standard,the model coordination between IEC 61850 and IEC 61970,the function model application.It is in favor of later construction and development of the smart substation.
