摘要：

摘要：智能变电站网络承载站内监测和保护业务，具有实时性和可靠性等要求。在分析智能变电站通信业务特征的基础上，提出一种基于光突发交换机理的多级树型光交换网络架构。研究了光交换网络的主节点、从节点和边缘节点的结构和功能，并对过程层网络中的GOOSE、SV业务数据流进行了分析。最后阐述了基于Round-Robin调度算法的主节点控制平面的通信过程。

Abstract:

Communication network in smart substation carries monitoring and protection services,with real-time and reliability requirements.Based on the analysis of communication services characteristics in smart substation,a multilevel tree optical switching network architecture was proposed based on optical burst switch mechanism.Then,based on the structure and function of the primary node,slave node and edge node of optical switching network,and GOOSE,SV data flow in process layer network was analyzed.Finally,the communication process of the master node control plane based on the Round-Robin scheduling algorithm was described.

Key words: smart substation, multilevel tree optical switching network, scheduling algorithm, data flow analysis
