| dc.description.abstract | The use of renewable energy sources, especially wind energy, has grown in popularity since the turn of the twenty-first century. The objectives of the study was aimed to enhance the model parameters' development for wind energy production. The variable speed operations of the doubly fed induction generator (DFIG) have led to its widespread application in wind turbines. There are many advantages to DFIG, including its the effectiveness of costs, increased reliability and efficiency, and its capacity to function both independently and along with the grid. Their sensitivity to grid disturbances and low reactive power capabilities when the system is coupled to a weak grid are among their drawbacks. The entire system uses the vector control technique for electrical equipment. Using the MATLAB/Simulink framework, the whole system which is made up of models and submodels is integrated and simulated. Moreover, control strategy design is required to get the wind turbine model to produce its maximum output power. This comprises grid side converter (GSC), indirect speed control, proportional-integral (PI), and rotor side converter (RSC) control. The current loops in the PI controller have been adjusted until the target value is reached, and the current components are designed to follow their references. The RSC regulates active and reactive power, torque, and flux. The RSC control designs the indirect speed control, which is utilized to push the torque to follow the maximum power curve. No matter the operating area, the purpose of GSC control is to keep the DC bus voltage constant. It does this by running at a unit power factor. A wind turbine-based DFIG's most typical magnitudes, performance, and control have been shown. It also includes simulation results and steady-state analytical findings that validate the DFIG system's functionality and control. Research has been done on the dynamic study of current loop behavior in a DFIG based on a wind turbine Additionally, the analysis includes the system's behavior under several grid failure scenarios, including symmetrical (balanced) and asymmetrical (unbalanced) voltage dips with crowbar protection. Key Words: Crowbar Protection, Symmetrical, Asymmetrical, Wind Turbine, Doubly Fed Induction Generator, Indirect Speed Control, Analysis of Dynamics. | en_US |
