Analysis Study of the Dynamic Behavior of a 2 MW Grid-Tied DFIG in Case of Asymmetrical Voltage Dips

It is well known that the generator is almost considered as the heart of the wind turbine; thus, in case of grid integration, the deep knowledge of this component in terms of its behavior during dynamical grid conditions such as faults and disturbances has attracted the attention of researchers in order to safe operate the wind turbine while enhancing its degree of protection and its grid fault ride-through capability. This paper presents a case analysis study validated by numerical simulation through MATLAB/Simulink environment of the dynamic behavior of a typical 2 MVA grid-tied doubly fed induction generator under an asymmetrical grid voltage dip scenario.
