基于电力线通信的工业供配电系统研究

Research on Industrial Power Supply and Distribution System Based on Power Line Communication

工业供配电系统作为智能电网的一个分支,越来越依赖于通信技术的应用。针对工业电气使用电压和供配电资源的分配差异,该研究在电力线通信的基础上,依据节点间信道状态信息提出了一种基于相邻节点关系的信道传输,利用跨层信息的路由协议,给出了本地路由器表构建与相邻节点之间的信道条件。通过局部最优逼近系统整体最优,实现以最小跳数达到目的地节点,从而获得最佳的转发路径,有效地减少了信息传输的延迟。仿真结果表明,提出的路由协议在工业供配电系统的多用户混合业务的通信网中相较传统路由协议有更好的路由效果。

As a branch of the smart grid, industrial power supply and distribution system is more and more dependent on the application of communication technology. In this paper, based on the communication between the nodes, a channel based on the relationship between adjacent nodes is proposed, and the routing protocol based on the cross-layer information is proposed. Based on the communication between the power lines and the power supply and distribution resources, the channel condition between the lo- cal router table construction and the neighboring nodes is given. By means of local optimal approximation to the overall system opti- mization, the minimum hop count is achieved to reach the destination node, so as to obtain the optimal forwarding path, which effec- tively reduces the delay of information transmission. The simulation results show that the proposed routing protocol has better routing effect than the traditional routing protocols in the multi - user hybrid service communication network of industrial power supply and distribution system.
