Abstract
Variasi kecepatan angin mengakibatkan daya listrik yang dihasilkan turbin juga bervariasi. untuk memperoleh daya maksimum maka kecepatan rotor turbin harus berada dinilai optimalnya. Kecepatan rotor dapat dikendalikan dengan cara memanipulasi torsi dari generator, metode ini disebut Torque Control. Dalam hal itu, dibutuhkan DC-DC converter sebagai aktuator pengendaliannya. Pada penelitian ini dilakukan perancangan supervisory control berbasis buck converter pada turbin angin HAWT. Supervisory control tersusun dari dua buah loop kontrol yang tersusun secara cascade serta algoritma reference formula sebagai supervisory level. Primary loop menggunakan mode kontrol proportional dengan proportional gain sebesar 0,3. sedangkan pada secondary loop menggunakan mode kontrol proportional integral dengan proportional gain sebesar 5,2 dan integral gain sebesar 0,1. Supervisory control berbasis buck converter mampu melakukan kontrol kecepatan turbin dengan performansi kontroller dengan nilai error steady state kurang dari 5%,peaktime sebesar 19 detik, risetime sebesar 17 detik,setling time sebesar 31,5 detik serta maximum overshoot sebesar 2,35. Adapun Supervisory control yang telah dilakukan berhasil diimplementasikan dan menghasilkan rata-rata peningkatan daya turbin sebesar 4,1% pada kecepatan angin 5 m/s dan 10,58% pada kecepatan angin 6 m/s serta 11,65% pada kecepan angin 7 m/s, dibandingkan dengan sistem turbin angin tanpa kontrol kecepatan.

The variation of wind speed causes electric power produced by the turbine to be unstable and not maximum due to the rotational speed of the rotor which is not in its optimal area. Rotor speed can be controlled by manipulating torque of the generator, this method is called Torque Control. Therefore, a DC-DC converter is needed as control actuator. This research design supervisory control based on buck converter on HAWT wind turbines. Supervisory control is consists of cascade control and extremum seeking algorithm as supervisory level. Primary loop uses proportional control mode with a proportional gain of 0.3. while the secondary loop uses proportional integral control mode with a proportional gain of 5.2 and an integral gain of 0.1. Buck converter-based supervisory control is able to control turbine speed with. with a error steady state value of less than 5%,peak time of 19 seconds, a rise time of 17 seconds, a setling time of 31.5 seconds and a maximum overshoot of 2.35. The Supervisory control that has been carried out was successfully implemented and resulted in an average increase in turbine power of 4.1% at wind speeds of 5 m / s and 10.58% at wind speeds of 6 m / s and 11.65% at a wind speed of 7 m / s, compared to wind turbine systems without speed control.
