Abstract: This paper work presents a study on the effect of wind speed, slip and field excitation on dynamic behaviour of multi-machine power systems installed with Doubly Fed Induction Generator (DFIG) based Wind Energy Conversion System (WECS). A method to construct linear model of DFIG, a framework for interfacing DFIG with multi-machine power systems, formation of system matrix and eigen-value analysis for the investigation of small signal stability are presented in this paper. A MATLAB program is developed and effectiveness of developed program is tested in a test system interfaced with DFIG. The impact of varying wind speed, slip and field excitation on the small signal stability analysis of multi-machine power system interfaced with DFIG is studied and the results are presented.
