ABSTRAK

Pengembangan pembangkit tenaga angin semakin mendapat perhatian dari kalangan pengusaha serta ilmuwan dikarenakan dalam ketersediaan energinya bersih dapat diperbarui dan dapat didistribusikan secara luas. Sementara sifat energi angin itu sendiri adalah memiliki kecepatan yang acak sehingga untuk itu pada pembangkit tenaga angin ini digunakan generator induksi yang bersifat fleksibilitas dari karakteristik kecepatan rotornya sehingga dapat mengurangi slip yang terjadi akibat kecepatan angin yang berubah ubah. DFIG merupakan salah satu jenis dari generator induksi yang mampu mengekstraksi energi angin untuk dikonversi ke energi listrik meskipun kecepatan turbin di bawah kecepatan sinkron. Pada sistem kerja DFIG sebelumnya dilakukan kontrol pada torsi dan blade pitch. Sinyal output dari torsi dan blade pitch ini merupakan hasil output dengan kontrol PI sebagai logika kontrol dan dibandingkan dengan data referensinya. Selanjutnya pada percobaan selanjutnya untuk model DFIG yang sama dilakukan pengontrolan pada torsinya menggunakan logika fuzzy logika ini menghasilkan output kontrol yang handal tanpa memerlukan suatu model matematis yang detail dari sistem. Input dari logika ini berdasarkan fungsi keanggotaannya dalam hal ini fungsi keanggotaannya diambil dari kecepatan angular rotor dan kecepatan angular rotor referensi. Sedangkan data angin yang digunakan pada percobaan ini mengambil data angin dari jembatan Suramadu dengan rata rata kecepatan angin terendahnya pada 863 ms. Tujuan akhir dari percobaan ini menghasilkan kesimpulan tentang analisis penerapan kontrol dengan logika fuzzy pada DFIG berdasarkan analisis pada output torsi elektromagnetik kecepatan angular rotor daya aktif dan daya reaktif menggunakan kontrol fuzzy dibandingkan dengan kontrol PI.


ABSTRACT

Development of wind power generating growing came to the attention of entrepreneur community and scientist because of in its energy availability clean renewable and can be distributed widely. Meanwhile characteristic of energy of itself wind is haves random speed until for that at this wind power generating used induction generator that have the character of flexibility from its rotor speedcharacteristic so it can less in slip that happened consequence of variable wind speed. DFIG is one of type from induction generator that can extract wind energy for converted to electrics energy though turbine speed under synchronize speed. At carier system DFIG previously conducted control at torsion and blade pitch. Output Signal from torsion and blade this pitch is output result by control PI as logical control and compared to its reference data. At experiment hereinafter to model DFIG in common conducted control at its torsion use fuzzy logic this logic produces reliable control output not requiring a mathematical model that detail from system. Input from this logic base its membership function in this case its membership function is taken away from speed angular rotor and speed angular reference rotor. Whereas wind data that used at this experiment take wind data from bridge Suramadu average of lowest wind speed at 863 ms. Final purpose from this experiment to make conclusion about analysis of control applying with fuzzy logic at DFIG based analysis on elektromagnetik torque angular speed active power and reactive power output using fuzzy control compared with PI control.



KeywordsInduction Generator, DFIG, torsion, blade pitch, control PI, control fuzzy, and speed angular rotor.
