Modeling of a wind turbine with a permanent magnet synchronous generator for real time simulations

This paper presents a mathematical model of a wind turbine that includes a permanent magnet synchronous machine (PMSG) for real time simulations. The dynamic model considers a stochastic model of the wind, a state-space representation of the wind turbine with the PMSG, avoiding the use of a gear box, and a back-to-back converter for the interconnection of system with the grid. A field oriented control technique in the dq reference frame was used for the converter, also a control loop for the pitch angle of the wind turbine was implemented. In order to show the performance of the controllers, they were implemented in an Arduino card and then connected to a specialized station in real time simulations. Case studies that show the dynamic behavior of the wind turbine are presented and discussed.
