为了降低尾流对风电场稳定输出和风力机发电性能的危害,在现存风电场风力机布置优化布局方法下,提出结合1种基于几何约束辅助的Voronoi图的全新优化方法,对现行的几种代表性的风电场布局进行二次迭代优化,并利用WAsP软件对优化前后的布局做对照数值仿真计算。研究结果表明:优化后的布局可有效规避尾流效应,提高风电系统的稳定输出性和安全供电,并提高风电能量利用率。本文以Voronoi几何生成特性为研究核心,在总结一般规律下,结合程序化计算思维、人工智能、计算机图形学算法等知识,深入探讨Voronoi风场布局计算模拟仿真的未来应用可行性,得出其提高精度的有效方法,同时为风电场布局理论和其他学科的交叉融合提供创新思路。

In order to reduce the harm of wake to the stable output of wind farms and the power generation performance of wind turbines,under the existing layout optimization methods of wind turbine in the wind farm,a new optimization method based on Voronoi diagram assisted by geometric constraints was proposed to conduct the secondary iterative optimization on the several existing representative layout of wind farm,and the comparative numerical simulation was carried out on the layout before and after optimization by using WAsP software.The results showed that the optimized layout could effectively avoid the wake effect,improve the stable output and safe power supply of wind power system,and improve the energy utilization rate of wind power.Taking the geometry generation characteristics of Voronoi as the research core,and based on the summary of general laws,combined with the knowledge of programmed calculation thinking,artificial intelligence and computer graphics algorithm,the feasibility of the future application of Voronoi wind field layout calculation simulation was discussed in depth,and the effective method to improve the accuracy was obtained.At the same time,it provides innovative ideas for the cross integration of wind farm layout theory and other disciplines.
