An experimental and numerical investigation on the power performance of 150Â kW horizontal axis wind turbine

In this paper, the computational fluid dynamics (CFD) based blade design simulations is performed to study the 150 kW horizontal axis wind turbine. Reynolds-averaged Navier-Stokes equations and RNG k-ε turbulence model are applied for computational simulations to predict turbulent flow. The predicted results show that under the 12 m/s rated wind speed, the output power are 180 kW, 82 kW and 56 kW on the pitch angle of 5, 15 and 30°, respectively. The maximum aerodynamic performance of 0.42 can be achieved on the pitch angle of 5 with TSR of 3.6. In order to validate the design, output of torque and power performance of the wind turbine under various wind speed have been measured. The comparisons demonstrate the reasonable agreements between experimental and numerical data under the pitch angle of 5° and 6-10 m/s wind speed.
