Abstract:

This paper presents a model based predictive direct power control (MPDPC) strategy to achieve soft and fast grid synchronization of doubly fed induction generator (DFIG) applied in wind energy applications. The future behavior of active and reactive powers is predicted in MPDPC using the discrete model of DFIG and the most appropriate voltage vector is selected to minimize the errors between the reference value and feedback value of active/reactive powers. Furthermore, the PI regulator and current loop in the existing methods are eliminated, featuring low complexity. The grid connection process is very quick and smooth without any overcurrent. The developed novel MPDPC is compared with prior method based on switching-table-based DPC (STDPC) and shows quicker response, better steady state performance and lower switching frequency, which are validated by the simulation results obtained from a 15 kW DFIG system. © 2011 IEEE.
