High penetration of wind power into the grid necessitates the coordinated action of wind energy conversion systems and the grid. A suitable generation control is required to fulfill the grid integration requirements, especially during faults. A system using a pair of voltage source converters with a squirrel cage induction generator coupled to a wind turbine is proposed to provide fault ride-through during grid faults. A threefold action is used for providing the effective fault ride-through via coordinated action of the machine side and the grid side converter. The entire wind energy conversion system is controlled such that the wind turbine remains connected even during the faults. To implement the threefold action: (i) A decoupled current controller is placed in the grid side converter, which separately controls the positive and negative sequence currents arising during faults. The grid side converter controller is capable of eliminating the double frequency oscillations at the dc-link voltage and, hence, real power, which arises during the unsymmetrical faults; (ii) Reactive power injection is additionally provided by the grid side converter for better grid support; and (iii) The vector control technique is used in machine side converter along with the droop control to adjust the generator speed and the torque resulting in actuation of the pitch control mechanism to limit power generation without shutdown of the turbine.

Under such circumstances, the WECS is expected to remain intact to the grid so that blackout is avoided.…”

“…Operating the system as per new grid codes may increase the cost. 18 A nonlinear controller design has been presented for power electronics device-based WECS that is capable of maintaining current levels within its design limits, even at significantly decreased voltage level during fault condition. The existing FRT control strategies consider only positive (+Ve) sequence currents, but during unsymmetrical fault, negative (−Ve) sequence components appear in the machine current.…”

Summary In this paper, an indirect vector control (IVC) technique for the stand‐alone self‐excited induction generator (SASEIG)‐based wind energy conversion system (WECS) is proposed to independently control torque, active power, reactive power, and DC voltage for variable wind speed operation without fault and constant wind speed operation with single line‐to‐ground (LG) fault condition. This independent control of the WECS is obtained by using two‐level back to back converter, ie, machine side converter (MSC) and load side converter (LSC). To improve the dynamic response of the system during wind speed changes and fault operation, the PI controller in IVC is replaced with fuzzy logic controller (FLC). IVC of SEIG‐based WECS has been simulated in MATLAB/SIMULINK software, and prototype model of the proposed WECS is designed to experimentally validate the performance using dSPACE DS‐1104 R&D controller board. The results demonstrate that the performance of the proposed FLC‐based IVC controller is better than that the conventional PI controller–based IVC during variable speed and LG fault operations.
