Double Fed Induction Generator

Pada zaman di mana energi terbarukan sudah mulai banyak digunakan, pembangkit listrik pun juga mulai beralih ke pembangkit dengan sumber energi yang terbarukan dan lebih ramah lingkungan. Salah satu sumber energi terbarukan yang biasa digunakan pada pembangkit listrik adalah angin. Doubly Fed Induction Generator (DFIG) merupakan sistem pembangkit tenaga angin yang dapat mengubah tenaga kinetik menjadi tenaga listrik. Pada penerapan DFIG permasalahan yang ditemui adalah tegangan keluaran tidak stabil dikarenakan kecepatan angin yang selalu berubah-ubah. Hal ini sangat merugikan konsumen sehingga ketidakstabilan tegangan akan mengakibatkan ketidakseimbangan sistem, bahkan akan mengakibatkan life time peralatan listrik menjadi pendek. Dengan control grid side yang dilengkapi dengan Fuzzy Logic sebagai upaya pembangkit listrik dapat menghasilkan tegangan stabil sesuai yang diinginkan pada setiap kondisi kecepatan angin yang berubah- ubah. Sehingga kestabilan tegangan DC tetap terjaga. Hasil simulasi pengujian ini menunujukkan jika pengontrol fuzzy logic dapat menjaga kestabilan tegangan DC yang diinginkan yaitu 1100V.

<span lang="EN-US">The following article presents the control of the power generated by the Doubly Fed Induction Generator, integrated into the wind system, whose rotor is linked to the power converters (Rotor Side Convert (RSC) and Grid Side Converter (GSC)) interfaced by the DC-BUS and connected to the grid via a filter (Rf, Lf) in order to obtain an optimal power to the grid and to ensure system stability. The objective of this study is to understand and to make the comparison between Sliding mode Control technique and the Flux Oriented Control in order to control the Doubly Fed Induction Generator powers exchanged with the grid, it also aims at maintaining the DC-BUS voltage constant and a unit power factor at the grid connection point.The results of simulation show the performance of the Sliding mode Control in terms of monitoring, and robustness with regard to the parametric variations, compared to the Flux Oriented Control. The performance of the systems was tested and compared with the use of MATLAB/Simulink software.</span>

Grid Side Converter

A mathematic model of the grid-side PWM converter based on Doubly-Fed Induction Generator (DFIG) has been investigated to analyze their operating characteristics. The control scheme to the grid-side PWM converter was presented. And the simulation model of the grid-side converter (GSC) based on DFIG energy generation system was built in Matlab / simulink software. The results show the feasibility and correctness of the control strategy.
