Performance comparison of direct power control for brushless doubly-fed wind power generator with different control winding structure

Recent Advances of Control Technologies for Brushless Doubly-Fed Generators

“…The proposed controller in [44] is robust to uncertainties toward parameter variations and achieves the constant converter switching frequency by using space vector modulation. In [45], the DPC based on the twelve sections has been adopted to implement the power tracking of the openwinding BDFIG system as illustrated in Fig. 5.…”

An overall Control of BDFIG using Direct Power Control for WECS under Unbalanced Grid Voltage Conditions

“…Finally, the voltage vector is selected from developed in [3], [30], according to dP, dQ, and the position of ψ sc . Relationship of CW stator voltage and flux vector is show in Figure4(a) [30].…”

“…Enormous efforts have been put in the advancement of WECS, to reduce costs, increase the efficiency and the reliability [1,2], with the sustained and rapid growth of world economy, the energy demand is increasing day by day, but a large amount of fossil fuel is used to lead to the environmental pollution aggravation. The wind energy as a clean and renewable energy accords with the future energy development [3]. The permanent magnet synchronous generator and the doubly fed induction generator based of WECS (PMSG WECS, DFIG-WECS) has become the most popular configuration for wind energy applications on one hand, The DFIG has several advantages including the maximum power capture over a wide speed range and decoupled active and reactive power control.…”
