海气边界层内风电场尾流及功率特性的中尺度数值模拟研究
Mesoscale numerical simulation of wind farm wake flow and power characteristics in the marine atmospheric boundary layer
摘要
Abstract
In this study,we explore the wake flow and power output of an offshore wind farm using the WRF model,coupling to an ocean model and a wind farm parameterization.It is found that the wake flow of the offshore wind farm significantly affects the operation characteristics of the whole farm.The wake flows of offshore wind turbines are easy to mix,result in a strong wind speed deficit,leading to the decline of power output of downstream wind turbines.The velocity deficit exhibits strong horizontal spread due to the flux exchange between air and ocean,accelerating the recovery of the wake flow,and ultimately leading to a reduction in the length of wake flow.Meanwhile,the wake characteristics and power output of wind farm are related to the layout and installed capacity of wind turbines.The air-ocean interaction increases the stability of wake flow extension,and help to reduce non-local impact.In general,it is important to consider the interaction between air,ocean and the wind farm itself.关键词
