Abstract

Doubly-fed wind generator is highly sensitive to voltage variations of the grid, which poses limitations for wind power plants during the grid integrated operation. This paper proposes a new control strategy for rotor side converter of doubly-fed induction generator (DFIG) using energy-based control method based on Port-Control Hamiltonian (PCH) theory and L2 disturbance attenuation. The proposed ride-through approach limits the peak values of the rotor inrush current, needs a lower rotor voltage and suppresses DFIG transient response at the times of occurrence and clearing the fault. The simulation results show that the proposed scheme has a good performance.
