摘　　要：[目的]文章旨在研究大型海上风电场的最佳规划容量设置。[方法]针对某1 GW容量的单个规划场址,利用3种不同单机容量机型与3种海上风电场尾流模型,结合海上风资源图谱开展同场址逐步扩容至2GW的一系列数值试验,并对全场发电量、尾流影响与边际效应进行分析。[结果]结果显示,随着机型的单机容量增大,扩容过程中全场实际发电量增幅越高,尾流损失增长越慢,兼顾机组安全性与投入产出比的有效扩容区间越大;但尾流模型选择可能影响有效扩容区间评估结果。[结论]文章研究表明,在满足现有用海指标、风电机组安全性与工程经济性等多重约束下,单个场址的最佳规划容量可以略高于现有基准值,在今后海上风电千万千瓦级基地规划中,应科学细分并合理设置单个场址的规划容量。[Introduction]This article aims to study the optimal planned capacity setting of large-scale offshore wind farm.[Method]A series of numerical experiments were conducted on a single planned site with a capacity of 1 GW using three models with different unit capacities and three offshore wind farm wake models,combined with an offshore wind resource atlas,to gradually expand it to 2 GW.Power generation,wake effects and marginal utility of the whole site were analyzed.[Result]The results show that employing the wind turbine with larger single-unit capacity,the higher gaining of the power generation and slower growth of wake loss appear during the capacity expansion.Meanwhile,the larger effective expansion range which taking into account the safety of the wind turbine and the marginal utility exists.However,evaluation of effective expansion range may be affected by wake model selection.[Conclusion]This article shows that the optimal planned capacity of a single offshore wind farm can be slightly higher than the existing benchmark when multiple constraints,such as utilization of sea area,wind turbine safety and economical efficiency are met.Individual site needs to be subdivided scientifically and the optimal planned capacity should be reasonably set in the future planning of offshore wind farm bases with capacities in the tens of millions of kilowatts.
