Study on Turbulence Intensity Calculated by WT for Safety Assessment of Wind Farms
Turbulence intensity has an important effect on fatigue load and ultimate load of wind turbine. Based on the wind measurement data of a wind farm in the Yunnan-Guizhou plateau, the turbulence intensity was calculated by CFD software Meteodyn WT. Turbulence matrix exported from WT was analyzed and th...

| Summary: | Turbulence intensity has an important effect on fatigue load and ultimate load of wind turbine. Based on the wind measurement data of a wind farm in the Yunnan-Guizhou plateau, the turbulence intensity was calculated by CFD software Meteodyn WT. Turbulence matrix exported from WT was analyzed and the analysis result was compared with NTM of IEC61400-1 standard for wind turbine to assess turbulence intensity, thereby evaluating safety of wind farms. In addition, a method to calculate Iref is proposed regarding the problem that turbulence typical value Iref cannot be exported directly from WT. |
