主 题:open-winding brushless doubly-fed reluctance generator(BDFRG) direct power control faulttolerant control multi-level converter wind power
摘 要:To improve the fault redundancy capability for the high reliability requirement of a brushless doubly-fed generation system applied to large offshore wind farms,the control winding of a brushless doubly-fed reluctance generator is designed as an open-winding ***,the two ends of the control winding are connected via dual three-phase converters for the emerging open-winding ***,a novel fault-tolerant control strategy based on the direct power control scheme is brought to focus in this *** on the direct power control(DPC)strategy,the post-fault voltage vector selection method is explained in detail according to the fault types of the dual *** fault-tolerant control strategy proposed enables the open-winding brushless doubly-fed reluctance generator(BDFRG)system to operate normally in one,two,or three switches fault of the converter,simultaneously achieving power tracking *** presented results verify the feasibility and validity of the scheme proposed.
