Enhancing the Performance of DFIG Wind Turbines Considering Excitation Parameters of the Insulated Gate Bipolar Transistors and a New PLL Scheme

The major aim for achieving the successful synchronization of a wind turbine system to grid is mitigate electrical and mechanical stresses on generator. During transient state, gearbox, shaft, rotor generator could be damaged due stress. stator windings generator, including its insulation, affected. This paper undertakes an extensive analysis effects excitation parameters power converter Insulated Gate Bipolar Transistors (IGBTs), state performance Doubly Fed Induction Generator (DFIG), considering different scenarios. optimal IGBTs were used further new Phase-Locked-Loop (PLL) scheme. PLL computes phase displacement required achieve orientation control. Consequently, it helps in preventing distortion stator-grid interphase. proposes approach that integrates control strategy Series Dynamic Braking Resistor (SDBR) augment fault ride through capability variable speed DFIG-based. SDBR post recovery Simulations run Power System Computer Aided Design Electromagnetic Transient Including DC (PSCAD/EMTDC) examine severe conditions, test robustness controllers employed. results show proposed hybrid aids fast DFIG variables during conditions.
