摘　　要：针对大规模智能终端接入云主站造成的调试工作量大、运维效率低的问题,提出了一种考虑网络优先级的配电网智能终端即插即用方法。首先,采用优先级函数和最优解相似度排序方法实现了网络接入策略的选择,以确保即插即用技术在配电网中的通信可靠性;然后,基于IEC61850通信标准构建了配电物联网的信息模型,并详细描述了即插即用技术的信息交互机制;参考工业互联网中的联合调试方法,提出了一种配电物联网的即插即用技术测试方法,该方法可以有效地检测智能终端的可靠接入。最后,搭建了一个实验平台,实验结果表明,所提出的即插即用技术可以有效地保证配电底层终端设备可靠接入。相比于传统的配置方法,接入效率提高了93.75%,具有良好的工程实用性。A plug and play(PnP)method for intelligent terminals in distribution networks that considers network priority is proposed to address the issues of high debugging workload and low operation and maintenance efficiency caused by the integration of large-scale in-telligent terminals into cloud master stations.Firstly,the priority function and optimal solution similarity ranking(SROS)method are used to select network access strategies to ensure the communication reliability of plug and play technology in the distribution network.Then,based on the IEC61850 communication standard,an information model for the distribution Internet of Things is constructed,and the information exchange mechanism of plug and play technology is described in detail.By referring to the joint debugging method in the industrial internet,a plug and play technology testing method for the distribution Internet of Things is proposed,which can effectively de-tect the reliable access of intelligent terminals.Finally,an experimental platform is built,and the experimental results show that the pro-posed plug and play technology can effectively ensure the reliable access of the distribution bottom terminal equipment.Compared to tra-ditional configuration methods,the access efficiency has been improved by 93.75%,which has good engineering practicality.
