摘要
随着“碳达峰、碳中和”目标的提出,清洁可再生的海上风能开发利用受到国家和行业的高度关注。当前,海上风电行业面临以技术创新驱动降本增效的发展态势,海上风电风机基础型式创新是重要手段之一。为评估将新型风机基础应用于海上风电工程的经济可行性,本研究构建了海上风电场工程全生命周期经济评估模型。以新型单桩-摩擦环复合式基础为例,考虑将其应用于总装机量为300 MW海上风电场情景,计算海上风电场在建设期内的成本和运营期内的主要经济指标。将单桩-摩擦环基础与传统单桩基础、导管架基础和高桩承台基础等进行对比,并对建设投资、上网产量和平价政策等影响海上风电场项目经济效益的主要因素进行敏感性分析。结果表明单桩-摩擦环新型基础相比于传统已有基础具有显著的经济优势,具有更优的抗风险能力。
With the goal of carbon peaking and carbon neutrality,the development and utilization of clean and renewable offshore wind energy have received great attention.Currently,the offshore wind industry is facing a development trend of cost reduction and efficiency improvement driven by technological innovation;The innovation of foundation type of offshore wind turbines is an important approach.To assess the economic feasibility of applying new types of foundations to offshore wind power projects,this study constructs a whole life cycle economic assessment model for these projects.A new pile-friction ring composite foundation is used as an example to evaluate the life-cycle economic benefits of applying it to an offshore wind farm with a total installed capacity of 300 MW,through calculating the construction cost of the farm and its main economic indicators during operation.This new foundation is compared with traditional pile foundations,conduit frame foundations,and high pile-bearing foundations.Sensitivity analysis is made on the main factors affecting the economic efficiency of offshore wind projects,such as construction investment,feed-in production,and parity policies.The results show the new foundation has significant economic advantages and better risk resistance.
