摘要：
This paper aims to compare the difference between GL 2010 and IEC 2005 standard with GH Bladed software and a III A direct drive wind turbine, including input parameters, calculation cases, calculation results of ultimate and fatigue loads. The analysis indicates that ultimate loads in blade root and hub with IEC 2005 are larger than those with GL 2010, but ultimate loads in tower and yaw bearing with GL 2010 are larger than those with IEC 2005. It showed that difference from wind conditions, calculation methods and statistic modes is responsible for the different ultimate loads. However fatigue computation results with GL 2010 standard are close to those with IEC 2005 standard. It recommends that wind turbine computations with IEC 2005 standard are suitable for great simulation of wind conditions and steady load results in statistics characteristic. ©, 2015, Science Press.
