Sistemas de controle aplicados a aerogeradores síncronos com conversores Back-to-Back

Abstract

The work presents the main concepts of the wind power system and wind turbine technology based on synchronous generators connected to the grid through a Back-to-Back converter. A mathematical modeling of the main components of the generation system is developed in this work as well as design of the controllers used to operate the system. The proposed wind generation system is constructed in the laboratory as well as new control platform based on a oating-point hardware to allow experimental testing. The wind turbine is emulated by an induction motor mechanically coupled to the synchronous generator. In this paper we used classical control techniques PI type in synchronous reference and non-linear based on passivity. A theoretical study on the control laws Interconnection and Damping Assignment Passivity-based Control - IDA-PBC in the application context is held and the controller design is presented. The in uence of the IDA-PBC controller parameters is also discussed. Maximum power tracking of the wind generator techniques are developed for simulation and practical system. Finally the simulated and experimental results for the developed system are presented and discussed.
