摘      要：To lower the difficulty of fault protection,a doubly-fed induction machine based shipboard propulsion system(DFIM-SPS)that is partially power decoupled is *** such an intrinsically safe SPS architecture,a synchronous generator(SG)is employed for power generation,and the accuracy of the parameters of power generation unit(PGU)plays an important role in SPS stable *** this paper,the PGU parameter deviations are studied to evaluate the effects on system *** models of salient-pole SG,type DC1A excitation system(EXS)and DFIM are illustrated ***,the corresponding control scheme is *** the 16 important parameters of PGU,up to 40%of parameter deviations are applied to implement parameter sensitivity ***,simulation studies are carried out to evaluate the parameter deviation effects on system performance in *** defining three parameter deviation effect indicators(PDEIs),the effects on the PGU output variables,which are the terminal voltage and output active power,are ***,the increasing rates of PDEIs with different degrees of parameter deviations for the key parameters are ***,the overall system performance is investigated for the two most influential PGU *** paper provides some vital clues on SG and EXS parameter identification for DFIM-SPS.
