当配电自动化系统与主网D5000系统进行图/模/数集成时，采用基于远程调阅和信息交互的主配网图/模/数集成系统。依托配电自动化系统中的数据中心进行主网输变电系统的模型信息导入时，主网输变电系统模型导入单元依据IEC 61970标准将主网输变电系统导出的CIM模型文件 导入配电自动化系统数据库中。该基于远程调阅和信息交互的主配网图/模/数集成系统可以只导入配电自动化系统功能需要的模型信息，不像现有的集成系统那样，为了使导入的图形信息显示完整而将图形信息中需要的所有模型信息都导入配电自动化系统中。该系统降低了冗余模型信息的导入，减少了导入和维护的工作量。
当配电自动化系统与主网D5000系统进行图/模/数集成时，采用基于远程调阅和信息交互的主配网图/模/数集成系统。依托配电自动化系统中的数据中心进行主网输变电系统中的实时数据导入时，使用事件服务机制。主网输变电系统将发生变化的实时数据生成事件信息发送到信息网络中，配电自动化系统通过数据中心监测信息网络中的事件信息，发现主网输变电系统最新的实时数据，并更新数据库中的相应数据。该基于远程调阅和信息交互的主配网图/模/数集成系统使得配电自动化系统与主网D5000系统的实时数据集成就像在主网输变电系统工作站与服务器之间进行一样，不需要用户手工维护、核对大量的前置通道信息和各实时数据的点号信息，大大减少了用户的工作量，并且主网输变电系统的实时数据集成不再通过前置服务器实现，减少了前置服务器的处理压力。
当配电自动化系统与其他不支持事件服务机制的主网输变电系统进行图/模/数集成时，采用基于远程调阅和信息交互的主配网图/模/数集成系统。依托配电自动化系统中的数据中心进行主网输变电系统中的实时数据导入时，使用消息机制，将主网输变电系统中发生变化的实时数据形成消息，通过消息总线发送给数据中心；数据中心接收到主网输变电系统发送的消息并将其转换为配电自动化系统要求的消息发送给配电自动化系统；配电自动化系统接收主网输变电系统发送的信息，解析消息中的模型信息、数据值及数据状态并将之存入数据库中。该基于远程调阅和信息交互的主配网图/模/数集成系统只依赖模型信息中的量测关键字，主网输变电系统中的模型信息导入时会自动将量测关键字导入数据库中，不需要用户手工维护、核对大量的前置通道信息和各实时数据的点号信息，大大减少了用户的工作量。并且该基于远程调阅和信息交互的主配网图/模/数集成系统是通过消息总线进行消息传输，不再需要通过前置服务器实现，减少了前置服务器的处理压力。
以上内容显示和描述了本发明的基本原理、主要特征及优点。本行业的技术人员应该了解：本发明不受上述实施例的限制，上述实施例和说明书中描述的内容只用来说明本发明的原理。在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
