摘　　要：针对智能变电站通信系统以太网组网技术中传输时延抖动较大、环网结构健壮性差的问题,对智能变电站通信网络关键技术进行了研究。新型通信网络基于以太无源光网络和面向连接的交换方式,采用时延可测、业务隔离等技术;搭建实验网络,测试了不同网络负载情况下通信业务的实时性及可靠性指标。测试结果表明,新一代智能变电站通信网络架构能满足变电站业务对通信网络的技术要求,验证了该技术方案的可行性。In order to solve larger transmission delay jitter and poor robustness of ring network structure in intelligent substa- tion communication system, the key technology of intelligent substation communication network is studied. The new communi- cation network based on Ethernet Passive Optical Network （EPON） and connection-oriented switch uses measurable delay, business isolation and other technologies. The test results show that the new generation intelligent substation communication network architecture can satisfy the technical requirements of communication services, which is verified to be effective based on the proposed technical scheme.
