Integrated mechanical and electrical non-salient pole PMSG-based wind turbine model development with predictive direct torque control

This work concerns the development of a completed permanent magnet synchronous generator (PMSG) wind turbine model. It considers the interaction between its mechanical and electrical parts. The mechanical part was established using FAST (which is an abbreviation of Fatigue, Aerodynamics, Structures, and Turbulence). In the electrical part, the predictive direct torque control method is used to control the PMSG using a two-level voltage source inverter, which performs three switching operations in a sampling period to control accurately the electrical torque and amplitude of the stator flux. This control strategy enables the PMSG to be controlled with a very low sampling frequency. Currently, most relevant works model the mechanical and electrical parts of a wind turbine separately. In this work, both systems are discussed in detail and integrated into a complete model of a PMSG-based wind turbine system.
