A wind gust can cause severe dynamic conditions that affect the operational behavior of the whole doubly fed induction generator (DFIG) wind energy conversion system and, as a result, the quality of power exchanged with the grid. In addition, it can cause great disturbances to critical system's variables with possible damages to the system's construction—to mechanical or electrical part. The knowledge...
In this paper an investigation of the Doubly-Fed Induction Generator's start-up procedure, using zero crossing method for the grid voltage's angle's calculation, is carried out in the environment of Matlab/ Simulink. Moreover, the significance of the phase displacement and the amplitude deviation of the stator voltage in the system's synchronization procedure is highlighted via simulation.
The main objective of this paper is to investigate the behaviour of Doubly-Fed Induction Generator (DFIG) under various grid disturbances. In order to study the dynamic response of DFIG, to emerge the faults' consequences, a model has been simulated in Matlab/Simulink. In addition, FFT analysis has been done to achieve fault diagnosis and identification. The disturbances that have been investigated...
In this paper, the wind energy conversion system that uses the “Cascade technology” especially the structure of Doubly-Fed Induction Generator (DFIG) is presented and analyzed. Moreover, a simulation of this wind energy conversion system in MATLAB/SIMULINK under different wind speeds is done and the results are presented and evaluated. Furthermore, a simulation under faulty conditions is held. More...
In this paper, the wind energy conversion system that uses the structure of Doubly-Fed Induction Generator (DFIG) under fault condition is presented. Moreover, a simulation of this wind energy conversion system under fault conditions in MATLAB/ SIMULINK is done and the results are evaluated. Two typical cases of fault, open-circuit faults in two IGBTs in Rotor Side Converter and in one diode in Grid...
In this paper, a wind energy conversion system that uses the “Cascade technology” especially the structure of Doubly-Fed Induction Generator (DFIG) is presented and analyzed. Moreover, a simulation of this wind energy conversion system under fault conditions in MATLAB/ SIMULINK is done and the results are evaluated. Open-circuit faults in one IGBT or in two IGBTs are studied.
