Abstract

The wind turbine (WT) based on a Doubly Fed Induction Generator (DFIG) has experienced a fast evolution in the world, which leads to an increasing insertion of this type of generators in WTs connected to the electrical networks. When a voltage dips appears on the grid, the aero-generator can lose its operation, the voltage drop produces high peaks currents on the generator winding, without protection, the power converters will suffer also from over-current limit, as a consequence, it may be damaged and the DFIG be destroyed. In this chapter a new Direct Power Control (DPC) approach was applied, to improve the aero-generator operation under the network faults. The DPC approach was designed using the nonlinear Back-Stepping Controller (BSC) to ensure the robustness of the system. A comparison study was investigated to verify the performances of the DPC-based-BSC to that of the vector control (VC) based Proportional-Integral (PI). All were simulated using the Matlab/Simulink® environment. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
