In this study, the LabVIEW modeling of a permanent magnet synchronous generator that will be used in wind turbine and the voltage control with artificial neural networks on the model are done. Typically synchronous, asynchronous and direct current generators are used in wind turbines. In the scope of this study, synchronous generators are preferred due to the advantages such as high efficiency and high reliability. The artificial neural networks are used in the control of excitation circuit in taking into account the dynamic nature of the wind. © 2012 IEEE.
