bladePitch Problems

[chatianming]

Dear everyone:
I have problems in simulating the 5MW wind turbine in the process of validation of the simulation for SOWFA.
In those cases less than the rated wind speed(11.4m/s), the results in SOWFA are consistent with the other results. Howerver, at higher wind speeds(such as 15ms/,20m/s), I have configured the corresponding pitch angles at the SOWFA at the fixed wind speeds. But the power at higher wind speeds cannot be consistent with the other results, I cannot find the reasons. Could you give me some suggestions?

thank you!
best wishes.
