Study on the Aerodynamics and Control Characteristics of 5 MW Wind Turbine

摘要: Abstract 5MW wind turbine is regarded as a promising system for offshore farms in the western sea of Korean. And developed many companies but not much information known about it. In this study, aerodynamics and control characteristics depending on several methods reviewed turbine, which configuration data are used from previous study NREL. For calculations, GH_Bladed, certificated software by GL, compared with FAST code This shows that how power production, aerodynamic performances loads can be obtained different controls operation expected to useful design system.
