Abstract
In wind farms which mean many wind turbines constructed in a site, the wind passed through an upstream wind turbine (i.e., wind turbine wake) flows in a downstream wind turbine. As a result, the wake causes power reduction and fatigue load on the downstream wind turbine. Therefore, it is important to clarify the characteristics of wind turbine wake. In this study, by using a test wind turbine and wind speed measurement systems, the wind speed distribution in the wake were measured in non-yawed and yawed conditions in field and the effects of yawed inflow on the wake characteristics were clarified. A gaussian wake model for non-yawed and yawed conditions was investigated and compared with the experimental results.
