ABSTRACT: During the 14th Five Year Plan period, China's offshore wind power gradually entered a rapid development
period of large-scale wind turbines, large-scale wind farm connections, and deep-and-far-sea wind farm site selection. More
and more offshore wind power transmission plans have been proposed. The active commutation type high-voltage direct
current transmission system (ACC-HVDC) has attracted much attention due to its advantages of small size, light weight, and
low cost of offshore converter equipment. However, there is currently a lack of systematic economic analysis of several typical
transmission schemes in multiple scenarios. This paper improved the total life cycle cost (TLCC) model with financial
parameters, combined with the levelized cost of energy (LCOE) model for break even point analysis (BEP), and integrated
multiple parameters to establish the TLCC-BEP offshore wind power economic evaluation model; Based on the sensitivity
analysis results of the model,the cost reduction and efficiency improvement measures under various scenarios were given.;
Then, based on the actual geographical data,an improved technical and economic calculation model was adopted to analyze the
cost characteristics and profitability of four schemes, namely HVAC, FFTS, VSC-HVDC and ACC-HVDC, in multiple
scenarios. Finally, the applicability range of the four transmission schemes was obtained.

摘要:“十四五”期间我国海上风电逐步进入风机大型化、联结规模化、选址深远海化的快速发展期,越来越多海上
风电 送出方案 被提出。主 动换相型直 流输电(active commutation type high-voltage direct current transmission system,
ACC-HVDC)以其离岸换流设备体积小、重量轻、成本低等优势备受关注,但目前缺乏对典型送出方案在多场景下的
系统性经济分析。该文以财务参数改进全生命周期成本(total life cycle cost, TLCC)模型,结合平准化度电成本
(levelized cost of energy, LCOE)模型进行盈亏平衡分析(break even point, BEP),将多参数进行融合建立 TLCC-BEP 海上
风电经济性评估模型;根据模型敏感性分析结果,给出了各方案多场景下的降本增效措施;以实际风场地理数据,采
用改进后的技术经济计算模型,在多场景下对高压交流、分频输电、柔性直流及主动换相直流 4种方案进行成本特性
及盈利能力分析,最终得到 4种送出方案的适用范围。
