摘　　要：低压电力线载波网络复杂,具有未知性与时变性等特点,难以像中压电力线载波一样根据线路物理拓扑结构组建载波网络。文章提出了一种基于"逻辑拓扑结构"组网的低压电力线载波通信组网方法,描述了建立该结构的算法,并进行了实验室仿真。结果表明,该算法能可靠地实现低压电力线载波的组网,虽需消耗一定的时间,但能满足目前低压电力线载波通信的实时性要求。With the characteristics of complicationk, unprediction and time-varying in low-voltage PLC network, it is difficult to draw a carry network according to its physical topological structure. This paper introduces a method of constructing a low-voltage PLC network based on logical topological structure, amd discusses its algorithm and simulation. The results show that this algorithm can be used in low-voltage PLC networking. Although with some time consuming, the algorithm can satisfy the real-time demand of low-voltage PLC.
