摘　　要：为提高低压配电网窄带电力线载波通信系统可靠性,本文提出了一种基于人工蜘蛛网的电力线载波通信组网模型。首先对新模型的结构特点及低压配电网物理拓扑映射为人工蛛网逻辑拓扑的组网过程进行了详细阐述,并提出新的组网算法及重路由算法。然后应用两状态马尔科夫模型表征通信终端节点的工作状态。最后对新路由算法的延时特性进行了详细的计算及建模分析。仿真实验表明新的网络模型在提高电力线通信可靠性方面具有一定优势。To enhance the reliability of narrowband power line communication （PLC） over low-voltage networks, a novel PLC model based on artificial cobweb is proposed in this paper. Firstly the characteristics of new model and the transformational process from physical topology of low voltage distribution network to artificially cobweb logical topology are thoroughly discussed, and networking algorithm and routing reconstruction algorithm are proposed. Then two-state transition Markov model is used to simulate a terminal node. Furthermore, the time delay characteristic of new algorithm is calculated and analyzed by modeling. The simulation results indicate that the novel network model has advantage in improving communication reliability of PLC networks.
