| dc.description.abstract | This project addresses the model based design of a horizontal axis wind turbine simulation using MATLAB/Simulink. Wind turbine consists of different subsystems that use different technologies. Usually different teams develop each subsystem in separate environments, integrate and test it after developing a prototype. This project, however, starts with specifications and requirement of the model to model the wholes system, integrate the system and test it in single environment before a prototype is developed. In order to analyze the dynamic and/or steady state behavior of a wind turbine, the basic components of a wind turbine are structured in several libraries. Mechanical components, electrical machinery, power converters, common models, transformers, measurements and control, for studying the whole system and the effect of the change of one of the wind turbine components in the wind turbine efficiency are presented. Basic blade geometry, force and moment equation of the wind turbine model component are presented as embedded system in the model. Each equation of the control system converted into block diagram for integrating with Simulink environment for each control system of the model compensator design optimization is done. The NACA four-digit airfoil profile generated based on the recommended analytical equations of NACA aerodynamics blade profile. The profile is changed into MATLAB code to BE embedded in Simulink environment. 3D animations of wind turbine and its component models are developed to show its motion and response for the various operating condition of the system. A graphical user interface (GUI) is built which makes any user of this model to test the power output and the various operating condition for the data of selected site that a user wants. For each control system of the model compensator design optimization is done. Results of the system simulation are presented in graphical form suitable for system performance determination. From the power output, pitch actuator force, pitch actuator torque, Yaw actuator torque and wind turbine parameters, the useful energy and power output are determined. | en_US |
