Summary: | The fast development of grid-integrated wind power introduces new requirements for the operation and control of power networks. In order to maintain the reliability of a host power grid, it is preferred that the grid-connected wind turbine should restore its normal operation with minimized power losses in events of grid fault. This paper presents the results for the transient performance of a 2MW doubly-fed induction generator (DFIG), a type of variable-speed wind turbine. The paper concentrates on transient performance of the said generator technology under open-switch grid faults. The simulation was performed using MATLAB - Simulink software. The results obtained have shown that the control schemes employed for the DFIG wind turbines played an effective role in the restoration of the normal operation for the wind turbine in response to grid faults. The results for both during and after the grid fault will be discussed in this paper. |
