Regarding on above solution that your advice me to change I was did it:
1. the mesh element no increase from 109,000 to 115858 nodes
2. max stagger iterations I put it into 4
3. For this one, I did not confirm it. From what I know two to five degrees of rotation per time step is for sliding mesh method.
FYI, the simulation was finished after a couple of days but my concern here the validation on that what I run in experimental and simulation analysis give the results a quite bigger gap. As an example, I want to know the rpm of the wind turbine. In the experiment, the rpm is 207 and the simulation the rpm is 92.
Btw, thanks in advance for your response acupro.
