چکیده

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 kecepatan berubah secara signifikan akanmenyebabkan masalah jatuh tegangan, timbulnya distorsi harmonik, tegangan tidak stabil, danlain-lain. Dengan filter pasif dapat mengurangi harmonisa sekecil mungkin hinggabentuk gelombangnya semakin mendekati sinusoidal. Pada penelitian harmonisayang timbul pada sistem DFIG jenis passive single tuned (LC). Menunjukankondisi lebih baik setelah tipe tuned. Analisa besar total harmonic distortion (THD) dilakukan 5 skema penggunaan angin berbeda-beda denganrata-rata THD meningkat sebelum tipesingle 15.35% THDi, sesudah 1.40% THDi.Besar rata-rata eliminasi menghasilkan 11.63%.

Introduction to Doubly-Fed Induction Generator for Wind Power Applications

This chapter introduces the operation and control of a Doubly-fed Induction Generator (DFIG) system. The DFIG is currently the system of choice for multi-MW wind turbines. The aerodynamic system must be capable of operating over a wide wind speed range in order to achieve optimum aerodynamic efficiency by tracking the optimum tip-speed ratio. Therefore, the generator’s rotor must be able to ope...
