摘　　要：雅砻江流域基于同步数字体系(synchronous digital hierarchy,SDH)的现有通信组织方式无法满足一体化能源基地建设需求,在分析现有通信网面临问题和流域集控调度通信网后续需求的基础上,针对场站投运数量与带宽需求的关系给出带宽分配组网策略及估算方法。提出一种基于光传送网(optical transport network,OTN)源网服务平台的流域集控调度通信网建设方案,从技术体制选择、业务落地方式、长站距接入关键技术、自愈保护机制建立等方面进行具体技术探讨和工程建设构想。文章探讨的通信组网需求方案结合工程实际建立理论估算模型,方案充分利用厂网已有资源有效降低补充建设的生产投入,对于后续系统工程的分阶段实施具有现实参考意义。The existing communication organization modality based on synchronous digital hierarchy(SDH)within the Yalong watershed can’t satisfy the demands for the construction of the Yalong River energy base with integrated hydro,wind,and solar power.Grounded on the analysis of the issues confronted by the extant communication network and the subsequent requirements of the centralized control and dispatch communication network in the basin,the bandwidth allocation networking strategy and estimation approach are presented in accordance with the relationship between the quantity of stations put into operation and the bandwidth requirements.A construction blueprint for the centralized control and dispatch communication network in the basin founded on the optical transport network(OTN)source-network service platform is put forward,and specific technical deliberations and engineering construction notions are carried out in terms of technology system selection,business landing modality,key technologies for long-station-distance access,and the establishment of self-healing protection mechanisms.The communication networking demand scheme expounded in this paper establishes a theoretical estimation model in conjunction with engineering practice.The scheme avails itself fully of the existing resources of the plants and the grid to efficaciously reduce the production input for supplementary construction,and holds practical reference significance for the phased implementation of subsequent system engineering.
