Abstract

Desain wind turbine konvensional tanpa adanya system kontrol dapat menyebabkan kerja wind turbine kurang optimal. Hal ini karena energi yang ditangkap sangat bergantung pada naik turunnya kecepatan angin. Dalam tugas akhir ini dirancang sebuah sistem kontrol pada wind turbine dengan metode blade pitch angle control system yang mengadopsi sistem control berbasis classic-fuzzy. Tujuannya adalah untuk menjaga kecepatan putar shaft agar tetap pada range operasi generator, yang dianalogikan dengan sebuah nilai set point tertentu yang akan dipertahankan oleh kontroler. Variabel inputnya adalah kecepatan sudut shaft yang disensor menggunakan rotary encoder. Berdasarkan kecepatan sudut shaft, sistem kontrol mengendalikan sudut kemiringan dari blade (angle of attack). Perubaban sudut serang ini akan secara signifikan mempengaruhi kecepatan putar shaft. Pada pengujiannya diterapkan dua sistem Kontrol Logika Fuzzy (KLF) dengan perbedaan fungsi keanggotaan output. Kontroler pertama dinilai gagal melakukan aksi kontrol karena nilai eror steady state diatas 5%. Sedangkan kontroler kedua yang merupakan pembabaruan terhadap kontroler pertama dapat bekerja dengan baik dalam mempertabankan set point. lni membuktikan babwa penerapan blade pitch angle control system pada wind turbin dinilai efektif

Conventional wind turbine designs without a control system can cause the wind turbine to work less than optimally. This is because the energy captured is very dependent on the rise and fall of wind speed. In this final project, a control system for a wind turbine is designed using the blade pitch angle control system method which adopts a classic-fuzzy based control system. The aim is to maintain the shaft rotation speed to remain within the generator operating range, which is analogous to a certain set point value that will be maintained by the controller. The input variable is the angular speed of the shaft which is sensored using a rotary encoder. Based on the angular speed of the shaft, the control system controls the inclination angle of the blade (angle of attack). Changing the angle of attack will significantly affect the shaft rotation speed. In the test, two Fuzzy Logic Control (KLF) systems were applied with different output membership functions. The first controller was deemed to have failed to carry out control actions because the steady state error value was above 5%. Meanwhile, the second controller which is an update to the first controller can work well in fixing the set point. This proves that the application of the blade pitch angle control system in wind turbines is considered effective
