Experimental investigation of grid-connected operations for DFIG-based wind turbines with asymmetrical grid faults

Zheng Zhon

Abstract

Safe grid-connected operation of doubly-fed induction generator( DFIG) based wind turbines during the second period of asymmetrical grid fault ride-through while assuring that the reactive power support requirement of the grid is met requires proper control objectives for the rotor side converter( RSC) and proper control priorities for the converter for its current constraints. An RSC current reference calculation algorithm was designed to meet these requirements. Tests on a 3 kW DFIG test platform showed the effectiveness of the RSC current reference calculation algorithm during the second period of asymmetrical grid fault ride-through.
