Research Progress on Multi-terminal Transmission and Networking Methods for Ultra-large-scale Offshore Wind Power Development
千万千瓦级超大规模远海风电集群开发面临全新的送出与组网运行挑战.该文对现有的海上风电送出方式与新型紧凑化直流换流方案进行梳理,分析了多端直流组网的网架拓扑结构及海陆衔接问题,并综合对比评估了多种直流送出-组网组合方案的技术经济性.在送出方式上,直流送出仍然是远海大容量风电的优选方案,但亟需解决海上换流站的紧凑化问题.在组网拓扑上,星形枢纽组网具有综合优势,海陆输送通道一体衔接的陆上直流枢纽组网方案更适用于超大规模风电送至负荷中心的场景.基于紧凑型换流装备的多端直流枢纽组网是远海大容量风电开发的重要方式,未来需要在新型大容量低成本紧凑化换流装备研制、系统多级协同控制运行机理及海陆一体系统的全局故障穿越技术方面寻求重点突破.
Developing 10-GW-level far-offshore wind clusters poses unprecedented transmission and networking chal-lenges.This paper reviews existing offshore wind transmission modes and novel compact DC converter schemes,analyzes multi-terminal DC grid topologies and offshore-onshore interfaces,and evaluates the economic performance of various DC transmission-networking combinations.For transmission schemes,while DC transmission remains a preferred solution,there is an urgent need to address the issue of compact offshore converter stations.For networking topologies,the star-hub configuration offers comprehensive advantages,with onshore DC hubs and integrated offshore-onshore transmission being highly suitable for delivering ultra-large-scale offshore wind power to load centers.Multi-terminal DC hub networking using compact converters is vital for far-offshore,large-capacity wind power development.Future break-throughs are needed in novel large-capacity,low-cost compact converters,multi-level coordinated control principles,and integrated global fault ride-through techniques.
