Investigation on aerodynamic performance of a 1.5-MW wind turbine

The wind turbine test platform was developed in the CARDC 12m×16m low speed wind twnnel and its dependability has been validated by test.Using this plat form the experimental investigation on the aerodynamic performance of a 1/16 scaled model of 1.5MW wind turbine was conducted.And aerodynamic performance of the full scale wind turbine was calculated by GH Bladed software.The influence of pitch angle on C_p and the relationship between the rapid raise and sudden stop phenomenon of turbine and the aerodynamic performance of NH airfoils are analyzed through the test data,which are also compared with the results calculated using GH Bladed.The test results show that the maximun power coefficient of the test model is 0.492 and this value should be higher for the full-scale wind turbine by consideration of the Reynolds number.
