This dissertation is on control system for MW-class wind turbine. The basic control structure is on the performance of wind turbine and is a control system tracked power curve. To track the power curve, we discuss the control method for variable speed variable pitch that is used for torque control and pitch control. Furthermore, the MW-class wind turbine is a large structure and mechanical load created...
While the yaw system of the wind turbine operates depending on the wind direction, it makes us acquire the maximum energy and its own mechanical load decreased. Hence, the optimal design of yaw system is extremely important in the design process of the wind turbine. In this study, yaw system is introduced and its efficiency is analyzed by the result of early simulation.
To optimise the performance of the wind generation, wind turbines employ variable speed (VS) variable pitch (VP) control system. Wind turbine is a complex nonlinear mechanical system exposed to uncontrolled wind profiles. Due to this, dynamic and parametric uncertainties arise in the mathematical model of the wind turbines over different operating conditions. This makes the turbine controller design...
The wind turbine codes predict wind turbine loads and response in high accuracy and can be used in controller design with the development of the computer technologies. In this paper open source FAST code developed by NREL is studied. The wind turbine controller is designed in the Matlab/Simulink environment and the FAST code is modeled as an S-function. The simulation of the control algorithms with...
