智能配电网除传统的树状拓扑结构外，还将出现环网、格状网等结构。建立具有这些特殊拓扑配电网的电力线信道模型，并进行信道特性影响因素的分析是在智能配电网中应用电力线载波通信技术的必要前提和重要依据。通过基于信息节点的建模方法建立格状网拓扑的信道模型，并仿真分析前后主干长度、格网主干长度、分支长度、分支负载等因素对格网拓扑下信道传输特性的影响规律，重点分析了这些影响因素对信号衰减的影响。通过实验验证了所得结果的正确性和有效性。所提出的分析方法和所得结论为设计智能配电网电力线载波通信的调制方法提供了必要的理论基础和技术手段。

In the intelligent power distribution network, there are not only tree-topology but also ring-topology, mesh-topology and so on. To establish the power line channel models of the distribution networks with these special topologies and analyse the factors that influence the channel characteristics is the premise and the important basis in application of the PLC in smart distribution network. Based on a universal channel modeling method that is based on information nodes, this paper analyses the influence laws of multiple factors on channel transmission characteristics of the network with mesh topology through simulation, such as the front and rear trunk length, the mesh trunk length, the branch length and the load impedance. The correctness and general applicability of the proposed approach and the conclusions are verified through lab measurements. The proposed analysis method and the conclusions can be used as necessary theoretical basis and technical means to power-line communication modulation method.
