Winplex analysis software wind data statistics output example・We use collected raw wind measurement data to determine basic wind statistical quantities such as mean wind speed, wind direction and turbulence level.

・Site estimation validity conformity is checked with IEC61400-1 standard by using NEDO guidlines published at 2008.
Parameter Evaluation Example

1. Wind rose plot.
2. Annual mean wind speed given for each direction sector.
3. Weibull distribution (for wind speed total and for each direction sector).
4. Turbulence Intesity (for wind speed total and for each direction sector).
5. Ten minute data statistics: max and mean wind speed
6. Check and confirmation of the measured data with the neighbouring government measurements with possibility of micro-climate revision.

Wind climate analysis is performed by using state-of-the-art software such as MASCOT and WAsP.

【WAsP】
・Developed by Risoe Institute, it is used for predicting wind climate.
・Wind turbine/farm power production prediction.
・In the case of wind farms, wake loss influence effect is included.

By using FAST aeroelastic code, we perform ultimate and fatigue load case analysis of the wind turbine in compliance with IEC-61400-1 International Standard for wind turbine design. In addition, it is possible to use FAST aeroelastic code to analyze aerodynamic noise generated by wind turbine blades.

NASTRAN stress level map output of the 5MW wind turbine blade during the ultimate load By using NASTRAN FEM model, we analyize ultimate and fatigue load cases on wind turbine blade in accordance with IEC-61400-1 International Standard for wind turbine design.
