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...

The paper deals with a Doubly Fed Induction Machine (DFIM). It presents a study of an active power distribution law between stator and rotor sides. The DFIM is supplied by two voltages PWM inverters in stator and rotor. The power distribution law imposes a relation between rotoric and statoric pulsations. Due to this relation, a new variation structure of the DFIM speed control is presented. Th...

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...

VFT (variable frequency transformer) has been recently used as an alternative to HVDC (high voltage direct current) to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster initial transient recovery, and has better natural damping capability. VFT is simply a DFIM (doubly-fed induction machine) where the machine torqu...

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...
