|Title: ||Implementation and Performance Analysis of a Multi Megawatt Variable Speed Wind Turbine using Matlab® and Simulink®|
|Authors: ||Kumar, Ashoke|
|Abstract: ||This thesis implements and investigates the functionality of the GE 3.6 MW Wind Turbine model implementated in Matlab® and Simulink® when exposed to a wind step and a frequency disturbance The robustness of the Wind Turbine is tested by varying the aerodynamic parameters p,max C and opt l . 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 behaviour. The pitch-angle tends to change, although it should not be the case for low-wind speed operation. The frequency response in the low-wind speed region of the investigated WT shows that an external signal added with the torque controller output in the frequency range of 0.4~1 Hz can be reflected unaffected on the electrical power output and when the gain of the torque controller is increased from the base case, the above mentioned frequency range changed to 0.6~1 Hz.|
