Control Strategy of PMSG in Variable Speed Wind Power System

Abstract:

Control strategy of permanent magnet synchronous generator (PMSG) in variable speed wind power system has been design in this paper. The decoupling control can be realized by PWM converter with the field oriented strategy, and a novel adjusted method is discussed with excitation component compensation. Power characters and model of wind turbine are studied, and the simple maximum power point tracking (MPPT) algorithm is executed. Moreover, the complete control strategy is expressed considering the model limit of PMSG. The design adopted can feasible realize the predominant control within the permissible wind speed. The analysis and investigation results all have been confirmed that the excellent dynamic states and steady states performances of the control strategy.
