Following the progress regarding renewable energy growth, this master thesis is meant to be a theoretical foundation regarding the fundamentals behind the operation of a hydro-kinetic river turbine. The problematic behind this new kind of equipment is introduced, then the permanent magnet synchronous machine is studied. It’s mechanical and electrical dynamic equations are developed, introducing at the same time the concept of the rotating reference frame used later on. The topology used in this application, a two level three phased bridge, is described and the equations characterizing it are explained in order to better understand the modulation strategies available. A brief history of those strategies is presented before bringing the focus toward space vector modulation which will be used in the current application. The different components are assembled in a Matlab simulation in order to test their compatibility. The simulation results are then compared with theoretical calculations to check the model validity. Several different control algorithm capable of tracking and maintain an optimal operating point are presented. The behaviour of a typical river is studied in order to establish the magnitude of the disturbances the algorithm will have to face. Finally, a new approach is introduced and compared to a more conventional one using another Matlab simulation model.
