摘　　要：低压配电网具有物理拓扑未知和电力线信道时变性特征。为提高低压配电网窄带电力线载波通信系统可靠性,提出并讨论一种基于非交叠分簇算法的电力线通信组网及路由重构方法。该算法可以根据信道质量的变化动态地建立、维护、优化电力线通信网络路由,保证通信网络的有效性。在此基础上,进一步提出并比较两种组网时间序列分配算法,完善了该路由算法。仿真试验表明,该路由算法具有很大的灵活性、实用性和有效性。Physical topology of low-voltage networks is unpredictable, and its Power Line Communication（PLC） channel is changeable. To enhance the reliability of narrow band PLC over low-voltage networks, a Power Line Communication routering reconstruction method on basis of irreciprocal clustering algorithm is proposed and thoroughly discussed in the paper. This algorithm can not only construct but also maintain and optimize PLC networks＇ dynamic routes in accord with variation of channel＇s quality. In addition, two kinds of time series algorithms are presented for the purpose of comparison. The time series algorithms make routing algorithm more mature. The emulation experiment has proven this routering algorithm has the characteristics of agility, practiceability and reliability.
