摘要
电力线载波(power-line carrier,PLC)技术是智能配电网重要的通信手段。为适应智能配电网可能出现的新的网络拓扑结构,提出一种基于信息节点的中压电力线信道建模方法。首先在网络关键位置设置信息节点,然后根据电路基本理论和均匀传输线理论推导出各信息节点间的电流电压关系式,最后利用传输矩阵方法得到信息接收点与发射点之间的电压传输特性。通过实验验证了该方法的正确性和普遍适用性。该方法可适用于树形、环网以及网格化等各种网络拓扑结构,为在智能配电网中压电力线采用载波通信技术提供了较好的分析方法。
PowerAine carrier （PLC） communication is an important communication method in smart power distribution grid. This paper proposed a novel channel modeling approach for the power line to deal with the new network topologies that may be formed in the future medium-voltage （MV） smart power distribution grid. This approach set information nodes at the key locations of the network at first, and then deduced the voltage-current relation between the information nodes according to the basic circuit theory and the even transmission line theory. Finally, the voltage transmission characteristics between information transmitter and receiver were obtained by using transfer matrix method. The correctness and general applicability of the proposed approach were verified through experiments. The proposed approach can be conveniently applied to networks with different topologies, such as tree topology, ring topology, mesh topology and so on, and provides an analytical method for the application of power-line communication in smart distribution grid.
