摘要
泵站技术升级是构建国家水网、实现“双碳”目标,以及统筹水资源、生态与能源安全的重要环节。国外泵站在水力设计、材料应用、信息化与能源协同方面已取得显著进展,表现为对极端工况的适应能力提升、智慧运维水平提高、生态运行方式完善以及绿色供能体系发展。然而,在高含沙、强腐蚀等复杂条件下,仍存在设计精度不足、故障预测不完善、生态响应机理不清晰及多能协同优化有限等问题。梳理了国外最新研究成果与工程实践,重点总结了反问题与机器学习融合设计、数字孪生技术、鱼类友好型流道与生态保护措施、风光储互补评价等关键技术,并提出面向国家水网及南水北调后续工程的技术路径,为“十五五”时期水利基础设施现代化与智慧水利建设提供参考。
Pumping station technology upgrading is an important part of building a national water network,realizing the goal of“dual carbon”,and integrating water resources,ecology and energy security.Overseas pumping stations have made significant progress in hydraulic design,material application,informatization and energy synergy,which is manifested in the enhancement of adaptability to extreme working conditions,improvement of the level of intelligent operation and maintenance,improvement of the ecological mode of operation and the development of green energy supply system.However,under complex conditions such as high sand content and strong corrosion,there are still problems such as insufficient design accuracy,imperfect failure prediction,unclear ecological response mechanism and limited multi-energy synergy optimization.In this paper,the latest foreign research results and engineering practices are sorted out,and key technologies such as inverse problem and machine learning fusion design,digital twin technology,fish-friendly flow channel and ecological protection measures,and wind-solar storage and complementary evaluation are summarized.It also proposes technical paths for the national water network and the follow-up project of South-to-North Water Diversion,which will provide reference for the modernization of water conservancy infrastructure and the construction of intelligent water conservancy during the 15th Five-Year Plan period.
