Simulador didático para estudo de controle de potência de turbinas eólicas

Abstract

The use of wind energy has grown exponentially in the last decade, especially in Brazil, which provides regions with great availability of wind and space. The capture of energy through the winds is carried out by wind turbines, commonly the large ones, allocated in large wind farms. Thus, the study of mathematical equations and computational simulations represent a great advance in the area, enabling the understanding of both wind technology and its control processes. In this sense, this work proposes the development of a didactic simulator to study the power control of wind turbines, implemented through a graphical interface in the App Designer environment of the Matlab software. From a literature review on the equations that

make up the wind generation, the use of software allowed for a simple and easy-to- implement approach. The graphical user interface allows modifying several parameters of the turbine to be simulated, such as height, radius, pitch angle (β), wind speed, and other factors, to obtain results of generated power and turbine behavior. The interface allows the user to perform the turbine power control simulating a real step control, thus facilitating the understanding of the process. Examples of turbine operation were performed in its operating regions, if any parameter was not correct for such a situation, the interface warns the user which procedure to do. The tool proved to be satisfactory and efficient for the didactic study of wind turbines.
