摘　　要：新型电力系统面向未来算力接入、算力互联等场景的新业务发展需求,对电力通信网络的承载能力、接入灵活性、多业务适应性等提出诸多挑战。针对现网大量存在的1 Gbit/s以下客户信号承载效率较低等问题,分析了提供小颗粒业务承载的细颗粒光传送网(fine grain optical transport network,fgOTN)技术体系,并结合实验数据,验证fgOTN的技术优势和可行性。结果表明,fgOTN相较于当前虚容器(virtual container,VC)/分组传输(packet transmission,PKT)/光通道数据单元(optical channel data unit,ODU)多平面光网络终端(optical transport network,OTN)承载技术在多个方面具有明显优势,fgOTN在新型电力系统中的应用部署及架构演进将是未来的研究重点。The development of the new electric power system for the future computing power access and computing power interconnection,many challenges are posed in the carrying capacity,access flexibility and multi-service adapt‐ability of the power communication network.In view of the problems of low carrier efficiency for customer signals below 1 Gbit/s in existing optical transport network(OTN)networks,the fine grain optical transport network(fgOTN)technical system that provides fine grain service bearers had been analyzed,and the technical advantages and feasibility of fgOTN based on key technical solutions and experimental data had also been validated.The results show that fgOTN has obvious advantages in many aspects compared with the current virtual container(VC)/packet transmission(PKT)/optical channel data unit(ODU)multi-plane OTN.How to deploy fgOTN in the existing net‐work and network evolution will be the focus of future research.
