This paper establishes a simulation model for a doubly fed induction generator (DFIG) connected with a power grid by using the vector control scheme. The model consists of a wind turbine, a doubly fed generator, power converters and a vector control strategy. The simulation model is built by using PSCAD/EMTDC. We also investigate the operating characteristics of a grid with the DFIG by considering respective wind speed fluctuation and short-circuit fault in the grid. Experiment results verify the correctness of the simulation model and the relative stability in the operating process of the simulated grid. This work provides a useful simulation platform for further studying the transient stability of the DFIG connected with power grid and more effective control strategies

The paper presents a decoupled direct power-controlled (DPC) of a doubly fed induction generator (DFIG) connected to an unbalanced power grid, executed in an orthogonal stationary reference frame related to the stator side. The control allows to maintain constant electromagnetic torque despite stator connection to the unbalanced power grid and to achieve controllable low-voltage ride through (LVRT) capability. The control does not require any signal decomposition into positive and negative sequence order, which allows to reduce its complexity and computational requirements. Then, the paper presents positive influence of rotor current feedback in the stator-controlled reference frame on control performance. It facilitates significant transient reduction and minor steady state control improvement. All the mentioned functionalities were validated both in simulation and in laboratory conditions and the obtained results are described in the paper.
