Parameter identification of doubly-fed induction generator by the Levenberg-Marquardt-Fletcher method

This paper presents a parameter identification approach based on the Levenberg-Marquardt-Fletcher (LMF) algorithm to obtain the doubly-fed induction generator (DFIG) parameters in case of incomplete or inaccurate parameters. The DFIG model and the LMF method are introduced at first. The parameter identification process is then described in details. The accuracy of the identified parameters is verified in a simulation case where real parameters are used as the reference values.
