A FRCC method based on rapid voltage response for LVRT recovery of D-PMSG

ABSTRACT

One of the main problems of large-scale wind power access to the power system is the fault ride-through (FRT) ability of wind turbine generator (WTG) at present. A fast-reactive current control (FRCC) method, based on rapid voltage response for the low-voltage ride through (LVRT) recovery of direct drive permanent magnet wind turbine (D-PMSG), is offered in order to solve the reactive power reversal phenomenon of D-PMSG during the reactive power recovery period after the end of LVRT. Initially, the technical regulations for voltage FRT of WTG in the world’s mainstream wind power markets are analyzed. Then, the reactive power reversal phenomenon of D-PMSG and its reason during reactive power recovery after LVRT are introduced. Afterward, an FRCC method based on rapid voltage response for LVRT recovery of D-PMSG is proposed, which is verified through improved IEEE standard three-machines nine-nodes test system. Finally, another reason for the voltage rose after the end of LVRT is further discussed according to the simulation results, and the conclusion and the next research direction are drawn.
