With the development of fiber optical communication, the power line carrier (PLC) communication is gradually becoming an auxiliary method in electric power communication. Most of the PLC channels have already been replaced by fiber channels and a lot of unused line traps have increased the electric energy loss. Based on an analysis of the high-frequency carrier channel structure and frequency allocation pattern,the graph theory is applied to establish a graphic modeling. The improved breadth-first traverse algorithm is used to search for the shortest path between two co-frequency use carrier channels influenced by unloading traps. By calculating the signal-to-crosstalk ratio of co-frequency use carrier channels in the shortest path, the decision on unloading traps is made. The accounting method is improved to make the accounting target more practical and examples are given to demonstrate the correctness of the method.

随着光纤通信的发展,电力线载波通信已逐渐成为电力系统通信的辅助手段,很多高压输电线路上的载波通道被光纤通信取代,线路上闲置的阻波器增加了电能的损耗。在分析高频载波通道结构和频率分配方式的基础上,应用图论理论进行了图形建模,采用改进的广度优先遍历(BFS)算法搜索受卸载阻波器影响的同频使用通道间的最短路径,通过对最短路径中同频通道串音防卫度核算,给出了阻波器卸载的决策。文中改进了核算方法,使核算指标更实用化,并以实例说明了该方法的正确性。
