摘要
[目的]针对现有通信条件难以满足海上风电场工程智慧运维和生态环境监测的需求,探索提出5G定制网方案,以解决海上风电场信号通达性差、网络覆盖不全以及流畅性低的问题。[方法]提出利用5G定制网技术打造了综合运维与监测方案,具体如下:通过在室外部署5G宏基站、塔筒内部署5G室分、水下铺设光网,实现风电场通信网络的立体覆盖;基于5G切片技术,实现一网多用以满足海上风电场对网络差异化的需求;在集控中心机房部署算力节点,通过边缘UPF(用户平面功能)转发专网数据实现算网融合。[结果]文章提出的基于5G技术的海上风电场智慧管理与生态环境监测方案已依托项目进行试点测试,测试结果表明5G基站的最大有效覆盖半径达到11.3 km,稳定传输上行速率达到5 Mbps,满足海域的观测数据回传、无人船视频回传的需求;通过在升压台和风机部署2个2.1G的8TR增强基站提升海域覆盖,绕风电场拉网测试验证了5G专网能够有效地覆盖风电场,覆盖率98.4%,可满足风电场的信号覆盖需求。[结论]通过5G专网覆盖风电场水上海域,通过STN(智能传送网)+水下光网实现水下通信,从而首创性地构筑了立体的海洋监测通信网络,为实现海上风电场的智慧管理与生态环境监测奠定了通信基础。
[Introduction]In response to the inability of existing communication conditions to meet the intelligent O&M and ecological monitoring needs of offshore wind farm,this article explores and proposes a 5G customized network scheme to solve the problems of poor signal accessibility,incomplete network coverage,and low smoothness in offshore wind farms.[Methods]In this paper,a comprehensive O&M and monitoring scheme was proposed by using 5G customized network technology,which was as follows:through the deployment of 5G macro base stations outdoors,5G indoor distribution in towers,and underwater laying of optical networks,the 3D coverage of wind farm communication networks was realized;Based on 5G slicing technology,one network could be used for multiple center computer room,and private network data was forwarded through the edge UPF(user plane function)to achieve computing-network integration.[Result]The intelligent management and ecological environment monitoring scheme for offshore wind farms based on 5G technology proposed in this article has been piloted and tested based on the project.The test results show that the maximum effective coverage radius of 5G base stations reaches 11.3 km,and the stable transmission uplink rate reaches 5 Mbps,meeting the needs of observation data return and unmanned ship video return in the sea area.By deploying two 2.1G 8TR enhanced base stations on the booster station and wind turbine to enhance sea area coverage,the pull-net test around the wind farm verified that the 5G private network can effectively cover wind farms,with a coverage rate of 98.4%,which can basically meet the coverage needs of the entire wind farm.[Conclusion]This scheme utilizes a 5G private network to cover the sea area of the wind farm and achieves underwater communication through STN(Smart Transport Network)and underwater optical networks.Consequently,it innovatively constructs a 3D ocean monitoring and communication network,laying the communication foundation for the intelligent management and ecological environment monitoring of offshore wind farms.
