INFLUENCIA DE LA RUGOSIDAD DE LA SUPERFICIE DEL MAR EN LA PRODUCCIÓN ENERGÉTICA DE LOS AEROGENERADORES MARINOS

Abstract

Offshore wind energy has more favorable wind conditions than its land counterpart, being necessary to maximize its use to make it more competitive. Thus, a more detailed analysis of the offshore wind potential that includes the interactions taking place in the atmospheric boundary layer is required. In similarity theory, the wind speed profile depends on the atmospheric stability and the roughness of the surface layer, and can be extended to open sea conditions, considering conditions of continuous variability of the roughness of the sea surface and neutral atmospheric stability. The objective of this paper is to characterize the influence of sea surface roughness on the energy production of offshore wind turbines in order to determine the energy viability of the implementation of new offshore wind farms, as well as for the prediction of its short-term energy production. For this, the wind speed profile is modeled by a potential equation and the logarithmic equation of similarity theory, and the results are compared with the data measured in the FINO3 research platform.
