摘　　要：建立了低压配电网电力线载波通信网络的一般路由模型,提出并讨论一种基于蚁群优化的电力线通信中继算法,该算法可以根据信道和通信链路的动态变化而动态地建立、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,进一步分析了所提出的中继算法在节点发生故障和信道质量明显下降时的可用性。仿真试验初步验证了该中继算法的有效性。The routing model is established for power-line carrier communications in low-voltage distribution.A power line communication relay method based on ant colony system algorithm is proposed and thoroughly discussed.The relay algorithm can construct and optimize PLC networks’ dynamic routes in accordance with the variation of channel’s quality.In additio n,the availability of the relay algorithm is analyzed when the channel quality is deteriorative and some nodes are out of work.The simulation experiment has proven its effectiveness.
