Abstract

Pada PLTU terdapat perangkat yang sangat sentral yakni boiler, Di dalam boiler terdapat komponen penting yakni steam drum sebagai tempat akumulasi air dan uap dalam sistem boiler. Ketinggian air pada steam drum merupakan indeks utama, sehingga diperlukan pengendalian level air tetap pada set point. Proses pengendalian level air pada steam drum memiliki ketidakstabilan yang kuat, menyebabkan penurunan kinerja kontroler yang mengakibatkan terjadinya integral windup. Sehingga pada tugas akhir ini dilakukan perancangan sistem PID Anti Windup yang mampu mengkompensasi ketidakstabilan yang bisa terjadi dan mempertahankan performansi sistem. Langkah awal yang dilakukan adalah pemodelan pada steam drum, selanjutnya dilakukan perancangan sistem PID Anti Windup. Uji performansi yang diberikan berupa uji validasi, uji close loop, dan uji Anti Windup dengan perubahan set point. Dari hasil simulasi menunjukkan bahwa sistem PID Anti Windup memiliki performansi jauh lebih baik dalam mengatasi fenomena windup dibandingkan dengan kontrol PID Konvensional. Pada sistem PID Anti Windup diperoleh nilai makximum overshoot 1.1% dan settling time 1039 detik. Sedangkan sistem PID Konvensional diperoleh nilai makximum overshoot 2.5 %, settling time 1145 detik.

In the PLTU there is a very central device, namely the boiler. Inside the boiler there is an important component, namely the steam drum as a place to accumulate air and steam in the boiler system. The air level in the steam drum is the main index, so it is necessary to control the air level to remain at the set point. The process of controlling the air level in the steam drum has strong instability, causing a decrease in controller performance which results in integral Windup. So that in this final assignment, the design of the Anti Windup PID system is carried out which can compensate for the instability that can occur and maintain system performance. The initial step taken is modeling on the steam drum, then the design of the Anti Windup PID system is carried out. The performance test given is in the form of a validation test, a close loop test, and an Anti Windup test with changes in the set point. The simulation results show that the Anti Windup PID system has a much better performance in overcoming the windup phenomenon compared to the Conventional PID control. In the Anti Windup PID system, the maximum overshoot value is 1.1% and the settling time is 1039 seconds. While the conventional PID system obtains a maximum overshoot value of 2.5%, settling time 1145 seconds.
