基于SPN的虚拟电厂多业务融合承载平台研究

Research on Unified Multi-service Bearing Platform for Virtual Power Plants Based on SPN

随着SDH技术的逐渐退出,传统分组网络在通道隔离能力、运维等方面存在不足,为满足未来虚拟电厂的多业务承载需要,提出基于SPN组网技术构建虚拟电厂的多业务融合承载平台,以SPN的软硬管道切片实现电力分区业务承载;以Telemetry技术实现网络精准、智能运维;以SDN架构满足业务突发性的需求,从业务满足度、网络性能、网络维护能力提升等方面对该平台进行分析,并在源深、卢家湾和灵石路3个站点建设小规模试点网络进行各项性能指标测试与实际业务验证,验证结果证明,该平台实现了虚拟电厂业务所需的信息贯通,电力分区业务承载性能指标满足业务和规约要求。

With the gradual facling away of SDH technology,the traditional packet network has shortcomings in channel isolation abili-ty,network operation and maintenance,etc.In order to satisfy the multi-service bearing demands of the Virtual Power Plant,a multi-service integrated bearing platform based on SPN networking technology was proposed,and the power division service bearing was real-ized by SPNs soft and hard pipe slices.Telemetry technology was used to realize accurate and itelligent net work operation and maintenance.The SDN architecture was used to meet the sudden demand of services,and the platform was analyzed from the aspects of busi-ness satisfaction,network performance,and network maintenance improwement.The small-scale pilot network is built at three stations of Y uanshen,Lujiawan,and Lingshi Road for various performance index tests and actual business verification.The verification results show that the platform has achieved the information penetration required for the virtual power plant services,The performance indicators of power zoning service meet the requirements of service and protocol.
