摘　　要：海上风力发电厂正在成为可再生电力生产的现实选择。作为海上风电场建设中较常用到的一种设计,平行四边形风电场进一步优化了风电机组排布,由此可以得到风电场最大发电量的优化方案。作为提高海上风电场盈利能力的工具,这项工作提出了第一个完整的非遗传进化算法,以优化平行四边形海上风电场的位置、大小和布局。该模型考虑了影响投资盈利能力的大多数相关经济数据,已经在海上风电场荷斯韦夫I(Horns Rev I,HR-I)的现场进行了测试。测试的结果显示,在10个优化结果的区域中心,确定了横轴与纵轴范围,平行四边形角度为(100~120)°,方向角度为(85~105)°,涡轮机之间行与列的距离分别为(9~20)m以及(5~8)m。涡轮机距离优化优化后的搜索时间为2 400 s,效率提升了14.29%。研究结果表明该方案在投资和年发电量方面与实际海上风电场的价值相似,均体现了最佳方向和盈利能力。Offshore wind power plants are becoming a practical choice for renewable power production.As a commonly used design in offshore wind farm construction,parallelogram wind farms further optimize the layout of wind turbines,thereby obtaining an optimization plan for the maximum power generation of wind farms.As a tool to improve the profitability of offshore wind farms,this work proposes the first complete non genetic evolutionary algorithm to optimize the location,size,and layout of parallelogram offshore wind farms.This model considers most relevant economic data that affects investment profitability and has been tested on-site at the Horns Rev I(HR-I)offshore wind farm.The test results showed that in the center of the 1o optimized regions,the horizontal and vertical axis ranges were determined,with parallelogram angles of 100 to 120 degrees and directional angles of 85 to 105 degrees.The distances between rows and columns of turbines were 9 to 20 meters and 5 to 8 meters,respectively.After optimizing the distance of the turbine,the search time was 2400 seconds,and the efficiency was improved by 14.29%.The research results indicate that the value of this plan is similar to that of actual offshore wind farms in terms of investment and annual power generation,both reflecting the best direction and profitability.
