This paper proposes a low voltage ride through (LVRT) scheme of doubly fed induction generator (DFIG) based on the supercapacitors energy storage. The novel control strategy of the bi-directional converter and the grid side converter is established. Simulation model of the DFIG system is developed. Simulation results show that the presented scheme can efficiently reduce the DC-link overvoltage, supply reactive power to the power system through grid side converter, and help grid recovery under system fault, improving the LVRT capability of the system.

As the number of doubly fed induction generator (DFIG)- based wind-turbine systems continues to increase, wind turbines are required to provide Low Voltage Ride-Through (LVRT) capability, especially under the condition of grid voltage dips. This paper, depending on the operating characteristics of doubly-fed induction generator during grid faults ,deals with a protection and control strategy on rotor-side converter (RSC) to enhance the low voltage ride through capability of a wind turbine driven doubly fed induction generator (DFIG). The simulation and experiment studies demonstrate the correctness of the developed model and the effectiveness of the control strategy for DFIG-based wind-turbine systems under such adverse grid conditions.

Grid Side Converter

A mathematic model of the grid-side PWM converter based on Doubly-Fed Induction Generator (DFIG) has been investigated to analyze their operating characteristics. The control scheme to the grid-side PWM converter was presented. And the simulation model of the grid-side converter (GSC) based on DFIG energy generation system was built in Matlab / simulink software. The results show the feasibility and correctness of the control strategy.
