Implementation and performance analysis of a multi megawatt variable speed Wind Turbine using Matlab® and Simulink®

This paper describes the implementation and investigation the functionality of the GE 3.6 MW Wind Turbine model implemented in Matlab^® and Simulink^® when exposed to a wind-step. The robustness of the Wind Turbine is tested by varying the aerodynamic parameters C_{p, max} and λ_opt. It is found that, the implemented model operate as expected in different wind speed regions under different disturbances e.g. wind speed step, grid-fault. However, while simulating in the low-wind speed region, it is found that, the pitch controller does not work according to the expected behavior. The pitch-angle tends to change, although it should not be the case for low-wind speed operation.
