Influence of Sea Surface Roughness and Wake Attenuation Coefficient on Power Generation of Offshore Wind Farms
Offshore wind farms are ushering in a period of accelerated development,and accurate assessment of power generation is crucial to the economic benefits of the project.The estimated power generation of offshore wind farms is very close to the actual value,but there is still a gap between the estimated power generation of off-shore wind farms and the actual value.In order to find a model that can accurately evaluate the power generation of offshore wind farms,this paper studies the commonly used wind farm power generation calculation software WasP to explore the impact of different parameter values on power generation.This study focuses on the rough-ness and wake attenuation coefficient,two parameters whose values have a significant impact on the power gen-eration,and calculates the impact of the roughness in the range of 0～0.005 and the wake attenuation coefficient in the range of 0.03～0.05 on the power generation,and gives value suggestions according to the actual project.The results show that the power generation decreases with the increase of roughness,and increases with the increase of wake attenuation coefficient.Through the research of this paper,the data basis and theoretical support are pro-vided for the evaluation of power generation of offshore wind farms,which has certain scientific significance and application value.
