NREL 5MW Wind Turbine Calculation 8MW power when pitch angle is changed.

Hello, nice to meet you.
I am a student studying Star-CCM+ at a university in Korea.
doing power calculations for NREL 5MW models.

At 11.4 m/s, the rated wind speed of the NREL 5MW turbine, approximately 5MW power could be seen.
However, after rotating the blade pitch angle, the wind speed was changed, resulting in greater power (8MW).

I referred to the table of fig.1 (Table 7-1).
Fixed / 12.1 rpm
velocity / 15m/s

Was there a problem with my setup?
