摘　　要：微型同步相量测量装置(distribution network phasor measurement unit, D-PMU)和高级量测设备(advanced mete ring infrastructure, AMI)等新型量测装置所采集的数据与传统配电网SCADA系统采集的数据一起成为了智能配电网广域量测与控制系统(distribution network wide area measurement and control system, D-WAMCS)的数据源。为弥补各系统在建设时遵循的建模标准不统一的缺陷,实现各系统数据之间的互通,本文首先对智能配电网混合量测体系架构进行了分析,比较了 D-PMU数据、AMI数据与SCADA数据在数据成分、数据精度、时标信息等方面的差异,提出了一种统一信息模型,对IEC 61850标准和IEC 61968 - 301 (CIM)标准的设备描述进行统一。利用示范区实际系统对所提模型进行了验证。The data collected by the new measurement devices,such as distribution network phasor measurement unit (D-PMU) and advanced metering infrastructure (AMI),together with the data collected by the traditional distribution network SCADA system,have become the data sources of the smart distribution network wide area measurement and control system (D-WAMCS).To make up for the disunity defect of modeling standards followed by each system during construction and to realize the exchange of data between each system,this paper first analyzes the hybrid measurement architecture of smart distribution network,and compares the differences among D-PMU data,AMI data and SCADA data in data components,data accuracy,time-scale information,etc.,then proposes a unified information model to unify the equipment description of both IEC 61850 standard and IEC 61968x301 (CIM) standard.The proposed model is verified by the actual system in the demonstration area.
