摘要
为了满足中压配电网配电自动化系统高可靠性、高实时性的数据传输需求,电力线载波通信(PLC)技术需要灵活可靠的路由组网算法。在分析中压配电网结构特点的基础上,提出了一种静动态中继相结合的分级分层PLC路由算法。根据中压配电网的拓扑结构,采用静态中继法将PLC网络分为3个级次,保证网络整体逻辑结构与配电网的物理结构大致相符,加快PLC网络的组网速度;每一级次内使用改进分层搜索算法进行动态中继自组网,保证组网的灵活性与可靠性。仿真结果表明所提算法能够根据配电网的结构及信道环境自适应地组网,路由优化过程兼顾了链路质量与中继负载均衡性;所提算法计算量小、组网速度快,通过调整算法中的权重参数可以灵活满足组网对可靠性与实时性的不同要求。
In order to meet the high reliability and high real-time requirement of data transmission in medium voltage distribution network automation system,PLC（Power Line Communication） technology needs flexible and reliable network routing algorithm. Based on the analysis of structure characteristics of medium voltage distribution network,a hierarchical classification PLC routing algorithm combinating static relay with dynamic relay is proposed. According to the topology of medium voltage distribution network,the PLC network is divided into three levels by static relay method,which can ensure the overall logical structure of the communication network conforming to the physical structure of the distribution network,and accelerate the networking process. An improved hierarchical search algorithm is used in each level to ensure the flexibility and reliability of networking. Simulative results show that the proposed algorithm can adapt to the network structure and the channel environment,and the routing optimization process takes the link quality and relay load balance into account. The proposed algorithm has low computational complexity and fast networking speed. By adjusting the weight parameters of the algorithm,it can meet the networking＇s different requirements of reliability and real-time.
