Abstract

Level air didalam steam drum perlu dijaga konstan pada titik tertentu. Oleh karena itu, diperlukan pengendalian untuk laju aliran air feedwater yang masuk agar menyesuaikan terhadap gangguan laju aliran uap yang keluar. Besar kecilnya laju aliran uap yang keluar bergantung pada permintaan beban. Jika permintaan beban tinggi dan fluktuasi, maka untuk memperahankan level air di dalam steam drum akan semakin sulit. Kontroler logika fuzzy tipe PID dengan skema robust self-tuning akan diimplementasikan pada sistem pengaturan level air dalam steam drum. Pada skema three-element control, ketika diberikan beban tinggi 700 MW sistem tersebut menghasilkan simpangan eror sebesar 15,69 mm peak terhadap set point-nya. Nilai tersebut lebih kecil dari pada skema single-element control dengan menghasilkan simpangan eror sebesar 18,5 mm terhadap set point-nya. Namun, ketika diberikan perubahan set point sebesar 40 mm skema three-element control menghasilkan respons 16,82 mm peak simpangan eror terhadap set point-nya. Nilai tersebut jauh lebih besar dari pada respons sistem dengan skema single-element control yang hanya menghasilkan simpangan eror 3,91 mm peak terhadap set point-nya. ================================================================================================ The water level in the steam drum needs to be kept constant at a certain point. Therefore, control is needed for the flow rate of incoming water feedwater to adjust to the disruption of the steam flow rate that comes out. The size of the steam flow rate that comes out depends on the load demand. If the demand for loads is high and fluctuations, then the water level in the steam drum will be more difficult. The PID type fuzzy logic controller with a robust self-tuning scheme will be implemented in the water level regulation system in the steam drum. In the three-element control scheme, when given a high load of 700 MW the system produces an error deviation of 15.69 mm peak against the set point. This value is smaller than the single-element control scheme by producing an error deviation of 18.5 mm against the set point. However, when given a set point change of 40 mm the three-element control scheme produced a response of 16.82 mm peak error error to the set point. This value is far greater than the system response with the single-element control scheme which only produces an error deviation of 3.91 mm peak against the set point.
