摘要 电网环境中由于用户经常会改变供电范围和供电对象,使负载发生变化,从而导致低压电力线网络的逻辑拓扑结构具有一定的"时变性",这种变化会导致通信信道的变化甚至通信链路发生中断,降低电力线通信的可靠性。本文主要介绍了IEC61334的路由方法及基于此常用的中继方法,并针对常用中继方法的弊端提出了一种中继优化方法,该方法解决了所有节点作为中继而带来局部范围的电网谐波系数超标的问题,又提供了静态配置的可能,为中继分配提供了灵活可变的方法,使得通信网络随着电网环境动态变化实时优化。该方法已经在海兴的AMI载波通信系统应用,实践证明增加了中继优化后通信的可靠性大大提高。 Load in power grid environment changed because end users usually change the objects which is supplied power often leads to the change of topology in power grid, and disconnect of the communication association, and PLC communication becomes not reliable. Routing mechanism of IEC61334 and the common repeating methods based on IEC61334 are introduced in this paper, and an advanced repeating method is promoted due to the disadvantages of the common ones. This method can solve the problem of over harmonic owing to all nodes as the repeater, it also supports static configuration for repeaters, so the communication network can be optimized along with the change of power grid. This method has been implemented in Hexing’ s AMI system, and it is proved that the reliability of communication be-comes much better because of advanced repeating method.
