Abstract
This paper presents the results of coupled analysis of CFD simulation of a two blade rigid wind turbine with an Independent Pitch Control (IPC) system in stable atmospheric boundary layer (ABL) condition. A CFD analysis code rFlow3D is applied to this computation. The IPC system is a load-based feedback type, which can control the pitch angle of the blades in a rated rotational frequency. The purpose of this study is to verify the applicability of the IPC system and its effect on load mitigation to wind turbine in stable condition. The results indicate that the IPC system is capable to reduce fluctuation for tilt moment. Furthermore, it is observed that the system is capable to lower fatigue load of yaw and tilt moment on rotor and thrust on a blade.
