Voltage dips are brief but frequent disturbances that can be defined as the most important problem affecting all electrical grids, it cannot completely avoided and represent main priority for industry. This study remains part of monitoring quality energy’s field. Its aim is to apply two approaches signals improving failure recognition in wind turbine conversion chain. One based on combination s...

Saat ini berbagai cara untuk memanfaatkan sumber energi terbarukan seperti angin, matahari, pasangsurut, hidro, dan lain-lain menggantikan fosil menjadi perhatian khusus. Energi anginmerupakan yang paling umum digunakan. Karena Doubly-Fed Induction Generator (DFIG) mengubahtegangan dari AC ke DC lalu diubah kembali dengan menggunakan Rotor Side Converter(RSC) Grid Converter (GSC) mana saat kece...

As one of the most promising Distributed Generation (DG) sources, wind power technology has been widely developed in recent years. Doubly fed induction generator (DFIG) is currently employed as one of the most common topologies for wind turbine generators (WTGs). This generator operates as a synchronous/asynchronous hybrid generators. Therefore, it is necessary to power engineers find understan...

This paper discusses a control system for the converter of doubly fed induction generator (DFIG) driven by wind energy. The DFIG consists two main parts; rotor side (RSC) and grid (GSC). Two advanced methods GSC are presented here in this paper; vector strategy based on pulse width modulation (PWM) direct power (DPC). DPC is switching table voltage selection. In addition to position, quadrature...

The demand for electricity from renewable sources continues to rise, and with it, the need for more efficient wind energy conversion systems. Wind turbines equipped with a wound-rotor induction machine can be operated in a more efficient configuration than currently popular, with little to no change in system hardware. By coupling the machine to the grid inversely to the norm, losses in the sys...

This paper presents results of a study concerning the dynamic behaviour of a wind energy system powered by a doubly fed induction generator with the rotor connected to the electric network through an AC-AC converter. A tendency to put up more and more wind turbines can be observed all over the world. Also, there is awareness in taking into account the requirements of a clean environment, due to...

Wind energy is often installed in rural, remote areas characterized by weak, unbalanced power transmission grids. In induction wind generators, unbalanced three phase stator voltages cause a number of problems, including overheating and stress on the mechanical components from torque pulsations. Therefore, beyond a certain amount of unbalance (for example 6%), induction wind generators are swit...
