摘　　要：电力线通信技术是建设坚强智能电网的重要手段。低压电力线通信因其强干扰、强衰减和强时变特性,严重限制了信号的传输距离。为了改善这种情况,从网络层入手,提出了一种基于多因素加权的低压电力线通信组网算法。该算法对传统分簇算法进行改进,在选择簇头节点时综合考虑节点连通度、节点负载情况以及节点有效通信距离和等因素,旨在解决以单一变量作为选举条件的簇结构不稳定的问题,同时借鉴人工蛛网的思想,为节点引入可通信的同层邻居节点作为备份路径,解决路径单一问题。将该方法与传统算法进行了对比,实验结果表明,改进后的算法选择簇头的方式更为合理,有利于保障节点公平性和负载平衡,同时备份路径的存在保障了通信可靠性,对于提高低压电力线通信组网的灵活性有一定的指导意义。Power line communication technology is an important means to build strong smart grid.Low-voltage power line communication seriously limits the signal transmission distance because of its strong interference,strong attenuation and strong time-varying characteristics.To solve such problems,starting from the network layer,a low-voltage power line communication networking algorithm based on multi-factor weighting is proposed,which improves the traditional clustering algorithm.When selecting the cluster head node,it comprehensively considers factors such as connectivity,load and effective communication distance of node to solve the problem of unstable cluster structure with a single variable as the election condition.At the same time,with the idea of artificial cobweb,it introduces communicable neighbor nodes in the same layer as backup path to solve the problem of single path.Compared with the traditional algorithm,the experimental results show that the improved algorithm is more reasonable in selecting cluster heads,which helps to ensure node fairness and load balance.Meanwhile,the existence of backup path ensures communication reliability,which has certain guiding significance for improving the flexibility of low-voltage power line communication networking.
