In order to dynamically adapt to the changes in power line environment, communicate effectively and reliably and meet the increasing demand for power line carrier communications, an automatic relay distribution line carrier communication method is developed to improve the existing artificial fixed relay based on statistics. The algorithm process and detailed procedures are presented. By virtue of Matlab the algorithm process is simulated through an example. The simulation analysis is carried out with the information of each relay path provided. The signal-to-noise ratio of all paths is compared and a diagram of different optimal path simulation is also drawn. The simulation results show that the algorithm is easy to be implemented, and the automatic relay could be achieved effectively.%为了动态适应环境变化,有效可靠地进行通信,满足规模日益扩大的电力线通信的需要,研究了一种基于数据统计的自动中继配电网载波通信方法来改进现有的人工固定中继,给出了算法的流程和具体步骤,使用Matlab对一算例模拟了算法的实现过程,对算法进行了仿真分析,给出了各中继路径信息,对比了各路径的估算信噪比,画出了多次仿真最优路径号变化图.仿真结果证明该算法简单易行,能有效地实现自动中继.
