摘　　要：110kV高压配电网的自动化信息模型及其高级应用仍沿用输电网设备描述准则,缺乏针对自身特点的特殊处理。从自动化信息模型与高级应用示例2个角度出发,针对调度员所关注的高压配电网运行特点构建其功能结构化模型。分析了现有公共信息模型(CIM)对高压配电网结构与运行特点支撑不足,提出面向CIM的对象聚合封装方法,将高压配电系统以重新定义的功能单元类予以结构化描述,聚合后的信息模型按功能,可划分为描述110kV系统结构的配电容量单元和描述负荷位置与状态的实际负载单元,任意拓扑与状态均能通过这2种对象准确表述,并结合设备实时参数完成计算模型交互,在信息模型降维的同时生成研究态数据,以支撑地区电网能量管理系统高级应用。以某地区电网的实例测试表明了所提方法的有效性与前景。The automatic information model and the corresponding advanced application for 110 kV high-voltage distribution network（HVDN）still follows the description criterions for transmission network,revealing a lack of special treatment of its own features.Proceeding from the two main aspects in the research,the information model and its advanced application,a functional structure model is built for the features of HVDN of the dispatchers concern.The insufficient support of common information model（CIM）for the features and operating characteristics of HVDN is discussed,and a novel object-oriented clustering approach is proposed.The functional unit（FU）,which is composed of distribution capacity unit（DCU）and actual load unit（ALU）,is defined to describe the HVDN topology and operation status.Specifically,DCU is utilized to represent the operating structure of network,while ALU is used to locate and quantify the actual power load.Hence,any operating scenario can be easily modeled through the two non-standard power system class scripts. Moreover,by integrating operational parameters,the proposed information model supports the modeling script interoperation by dimensionality reduction at the same time.This process facilitates further development of advanced application based on the energy management system（EMS）.The case study of an urban high-voltage system shows the feasibility and future application prospects.
