Abstract :
This paper presents a ride-through simulation study of a 2-MW wind-power doubly fed induction generator (DFIG) under a short-term unsymmetrical network disturbance. The DFIG is represented by an analytical two-axis model with constant lumped parameters and by a finite element method (FEM)-based model. The model of the DFIG is coupled with the model of the active crowbar protected and direct torque controlled (DTC) frequency converter, the model of the main transformer, and a simple model of the grid. The simulation results show the ride-through capability of the studied doubly fed wind-power generator. The results obtained by means of an analytical model and FEM model are compared in order to reveal the influence of the different modeling approaches on the short-term transient simulation accuracy
