摘要: 泛在电力物联网的建设对配用电通信网的经济性、安全性、可靠性提出了更高的要求,科学合理的通信网络架构和配置方法是亟待研究的问题。文章首先提出了面向泛在电力物联网的智能配用电通信网络架构,分析了智能配用电业务的通信性能约束;然后针对配用电信息采集类业务,建立了基于排队论的通信带宽计算模型及以带宽利用率最大化为目标函数的带宽优化模型,并以某智能配电房改造项目为应用场景,求解并分析了其业务延时、丢包率、带宽利用率与带宽配置关系;最后借助OPNET仿真平台验证了所提方法的可行性。

Abstract: The construction of Ubiquitous Power Internet of Things asks for more stringent requirements on the economy, security and reliability of the communication networks in distribution system. Therefore, a well-designed communication network architecture and configuration method is essential to address this issue. First, this paper proposes a communication network architecture for Ubiquitous Power Internet of Things. Then, the communication performance constraints of smart distribution services are analyzed. According to the characteristics of the information collection services, a communication bandwidth calculation method based on queuing theory is established, whose objective function is the maximum of bandwidth utilization. On the basis of a reconstruction project of a smart distribution station, the service delay, packet loss probability, bandwidth utilization and bandwidth configuration relationship for the information collection services are calculated. Finally, the feasibility of the proposed method is verified by the OPNET modeler platform, which reveals that the proposed method in this paper is technically practical.

Key words: ubiquitous power internet of things, smart distribution, queuing theory, OPNET, communication analysis
