摘要
[目的]为了获得海上风场的最优机位排布方案,提升海上项目在全生命周期内的经济收益,必须对影响发电量的关键因素做详细分析。[方法]结合海上风场工程项目的实际案例,基于自主开发的海上机位自动优化算法,分别应用Jensen和Larsen两种单机组尾流模型的技术理论,对比了多机组间三种不同的尾流组合叠加方式,并考虑了风向年际变化对现有机组排布的影响,给出了对应的最优机位排布方案。[结果]计算结果显示:海上风向的年际变化是影响机位排布的关键因素,使用不同尾流模型对机位排布的影响较小,多机组间尾流叠加方式对机位排布没有影响。[结论]研究成果为工程项目中最优机位排布的选择提供了关键依据,避免了风场25年全生命周期内上亿元的经济损失。
[Introduction] The paper aims to obtain the optimal layout of offshore wind farm and gain the maximum profit in the project life-cycle,it is high necessary to analyze its impact factors.[Method] The own developed application was used to compare the wake models between Jensen and Larsen,different superposition algorithm among wind turbines and the interannual variability of wind direction,this disquisition had combined the practical offshore wind farm case to analyse and provide the optimal layout.[Result] The results we obtained demonstrate that the interannual variability of wind direction is the most key factor to layout,followed by the different wake model,with superposition algorithm least.[Conclusion] This work provides some guidance for further project on choosing the optimal layout,thus the billions of dollars in losses caused by interannual variability of wind direction can be avoided in life-cycle of 25 years.
