In late years, the renewable energy use is promoted, and, additionally, large-scale windfarms are constructed on a global scale by development of large and high efficiency wind turbine generator system (WTGS). As a WTGS grows larger, safety of WTGS tower is becoming more important. Wind loads acting on a WTGS consist of extreme wind condition and normal operating condition. About an extreme wind condition, there are already some studies, and evaluation way is suggested, but very few studies related to a wind load at normal operating conditions. In this study, evaluation of the equation for WTGS tower base moment suggested by Ishihara et al. and comparison with actual survey value in JSW WTGS J70 at normal operating condition are carried out.
