This paper presents the complete modeling and real-time simulation of wind turbine driven doubly-fed induction generator (DFIG) which feeds ac power to the utility grid. For that, two pulse width modulated voltage source converters are connected back to back between the rotor terminals and utility grid via common dc link. It is found that there are so many limitations in the conventional contro...

Abstract— The doubly-fed induction machine used as a wind turbine generator has recently received a great attention from the industrial and scientific communities. The reason is twofold: first, this machine easily produces a fixed frequency voltage from the stator windings when the rotor is driven at variable speed; second, the excitation power electronics converter feeding the rotor windings n...

Abstract The presented paper gives a detailed observation of the PQ related problems for WE based on EFIG or DFIG (Extra Doubly Fed Induction Generator. Fundamental Frequency Components are most typical reasons disruption power quality. On other hand, wind loading conditions also disrupt Numerous modes removing these were studied to get rid fundamental frequency components WES (Wind Energy Syst...

Wind is one of the most widely used nonconventional sources of energy. A back-to-back PWM converter is used as the excitation power supply for the doubly fed induction generator (DFIG) wind power generation of variable speed constant frequency (VSCF).The Simulink model and control strategy of converter which is connected between rotor and grid is analyzed. Stator-flux oriented vector control ap...

Variable speed operation of a wind turbine generator improves its energy capturing capability. Up to the present, the machines employed have been induction machines, conventional synchronous machines or DC machines. The major drawback of these machines is that a complicated arrangement of slip rings or commutators with brushes, and a full-rating power converter are required. Reliability and cos...

Wind energy today, has attracted widespread interest from among a variety of sources of renewable energy in the world. Owing to the increasing demand for production of electrical energy for electricity networks by using wind power, it is essential that wind power plants are actively incorporated in the network’s performance using an appropriate control system. In general, these wind power p...

The rapid depletion of conventional sources for power generation necessitates the need of renewable energy power plants. Renewable sources primarily wind and solar are available free of cost and counts for cleaner source of energy thereby reducing environmental concern. The potential of wind energy needs to be harnessed effectively for optimum power generation. Present research aims at comparis...

The power generation with non-renewable energy sources has very harmful effects on the environment as well as these sources are depleting. On the other side the renewable energy sources are quite unpredictable source of power. The best trade-off is to use the combination of both kind of sources to make a hybrid system so that their individual power generation constraints can be overcome. The hy...
