Grid disturbances, especially grid faults, have very unfavorable effect on the performance of wind turbine based Doubly Fed Induction Generator (DFIG). In this study active and reactive powers control of DFIG with STATCOM has been carried out to improve Fault Ride Through (FRT) capability of a wind turbine. In order to excel improvement of the DFIG behavior under grid fault disturbances, an opt...

Aiming at the problems of DC fault isolation and power surplus in HVDC system with large-scale wind farm (WF) integration after single-pole grounding fault, this article designs a modified current transfer modular multilevel converter (M-CT-MMC) topology dissipation functions. The can be isolated through coordination each branch M-CT-MMC. In terms consumption, control mode switching strategy M-...

In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...

Grid-feeding inverters require much better operation monitoring and improved performance for their safe efficient integration into the power system. Specifically, these must participate in grid stability enhancement under faulty conditions without any disconnection. In this regard, a fault ride-through capability is proposed an inductive filtered grid-feeding inverter, which controlled both pos...

-Doubly Fed Induction Generators (DFIGs)find a great deal of application among variable speed wind turbines because of their advantages like operation at variable speed, ability to produce active and reactive power in all the four quadrants, higher efficiency, and extracting maximum electric power at different velocities of wind with the help of speed variation of the rotor and the usage of con...
