Research on layout safety of wind farm under Voronoi wake avoidance

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.
