Abstract

Sistem pemompaan fluida memiliki peran krusial dalam berbagai sektor industri, terutama pada bidang minyak, gas, dan energi. Dalam kegiatan operasional pada fasilitas kilang penyimpanan, tekanan discharge merupakan parameter penting dalam menentukan kestabilan proses pemindahan minyak mentah (crude oil). Saat ini, pengendalian tekanan discharge pada fasilitas tersebut masih menggunakan mekanisme bukaan valve manual. Data historis mencatat terjadinya lonjakan tekanan hingga 397,5 psig akibat keterlambatan bukaan valve saat kecepatan putaran pompa dinaikkan. Penelitian ini bertujuan memodelkan sistem kendali tekanan fluida menggunakan PID untuk mengotomatisasi bukaan valve discharge. Arsitektur Software-in-the-Loop (SIL) dibangun dengan mengintegrasikan MATLAB/Simulink sebagai pemodelan Virtual Plant, PLC Emulator, Komunikasi OPC UA, serta HMI untuk monitoring. Tuning PID dilakukan dengan metode Ziegler-Nichols 1 untuk mempertahankan setpoint operasional 220 psig dan menjaga overshoot di bawah 230 psig (4,55%) saat terjadi perubahan kecepatan pompa. Hasil pengujian sistem terhadap data disturbance aktual membuktikan bahwa kontroler PID mampu mencegah lonjakan tekanan dengan overshoot maksimum sebesar 2,79%.

Fluid pumping systems play a crucial role in various industrial sectors, particularly in the oil, gas, and energy fields. In operational activities at storage refinery facilities, discharge pressure is a key parameter in determining the stability of the crude oil transfer process. Currently, discharge pressure control at the facility still utilizes a manual valve opening mechanism. Historical data recorded a pressure surge reaching up to 397,5 psig due to delayed valve opening when the pump rotational speed was increased. This research aims to model a fluid pressure control system using PID to automate the discharge valve opening. The Software-in-the-Loop (SIL) architecture is built by integrating MATLAB/Simulink as the Virtual Plant model, a PLC Emulator, OPC UA Communication, and an HMI for monitoring. PID tuning is conducted using the Ziegler-Nichols 1 method to maintain the 220 psig operational setpoint and keep the overshoot below 230 psig (4,55%) when pump speed changes occur. System testing results against actual disturbance data prove that the PID controller can prevent pressure surges with a maximum overshoot of 2,79%.
