Abstract

Pada Test Separator milik Total E&P Indonesie digunakan untuk memisahkan hydrocarbon berdasarkan masa jenis kedalam tiga fasa berupa minyak, air dan gas. Level minyak harus dijaga pada ketinggian 50%, karena jika melebihi atau kurang dari set point akan mengganggu proses pemisahan serta dapat mengaktifkan Level Alarm yang mengakibatkan shutdown system. Level diatur menggunakan kontroler Proportional Integral Derivative (PID). Namun karena penentuan parameter kontroler menggunakan metode trial and error. Respon data dari real plant yang didapat memiliki error steady state, overshoot dan time constant yang besar. Beberapa metode kontroler PID dapat digunakan yaitu Ziegler-Nichols, Cohen-Coon dan Analitik, dengan terlebih dahulu mendapatkan model matematis menggunakan identifikasi dinamis bentuk Auto Regressive Moving Average (ARMA) melalui metode Pendekatan Penyelesaian Persamaan Linier Simultan Parameter Total (P3LS-PT) dan ditentukan nilai Integral Absolute Error (IAE) terkecil dari beberapa model yang didapat. Hasil model yang didapat digunakan juga untuk training simulator Human Machine Interface (HMI). Hasil simulasi pengujian kontroler, didapatkan bahwa dari metode Analitik t*=t dengan parameter Kp=19.23076 dan ti=302.18 s memiliki respons terbaik dan memenuhi spesifikasi desain dengan 0% error steady state, 0% overshoot dan time constant 300.73 s, respons dengan gangguan memiliki error steady state 5% dan memiliki time constant 304.73 s, serta sinyal kontrol memiliki nilai fluktuatif terkecil sebesar 10.0323%. Hasil parameter kontroler dan simulator HMI akan menjadi rekomendasi serta media training bagi operator di Total E&P Indonesie. ================================================================================== In Test Separator belongs to Total E & P Indonesie used to separate hydrocarbon-based specify gravity into three phases types such as oil, water and gas. Oil level should be maintained at a height of 50%, because if it exceeds or is less than the set point will disrupt the process of separation and can activate the alarm level that will make shutdown system. The level is set using the controller Proportional Integral Derivative (PID). However, because the determination of the controller parameters using the trial and error method. Response data from real plant that has gained steady state error, the overshoot and the big time constant. Several methods of PID controllers can be used is the Ziegler- Nichols, Cohen-Coon and Analytical, by first obtaining a mathematical model using dynamic identification form Auto Regressive Moving Average (ARMA) through the method of Simultaneous Linear Equations Total Parameter Approach (P3LS-PT) and determined value Integral Absolute Error (IAE), The smallest of the models obtained. Results obtained model was also used for Human Machine Interface (HMI) training simulators. The simulation results of testing the controller, it was found that of the Analytical method t*=t parameters Kp = 19.23076 and ti = 302.18 s has the best response and meet design specifications with 0% error steady state, 0% overshoot and the time constant 300.73 s, the response with disturbance has a 5% error steady state and has a time constant 304.73 s, as well as the control signal having the smallest fluctuation value of 10.0323%. Results parameter controller and HMI simulator will be a recommendation as well as media training for operators at Total E & P Indonesie.
