RANCANG BANGUN LOCAL CONTROL UNIT LCU FLOW PADA DISTRIBUTED CONTROL SYSTEMS DCS MINIPLANT WORKSHOP INSTRUMENTASI

DESIGNING AND DEVELOPING LOCAL CONTROL UNIT LCU FLOW AT INSTRUMENTATION WORKSHOP MINIPLANTS DISTRIBUTED CONTROL SYSTEMS DCS

Author :
RIFKI, MUHAMAD 




ABSTRAK

Penggunaan Distributed Control System DCS sebagai sistem kontrol sudah sangat umum pada plant yang berukuran besar dan kompleks. Pada proses yang menggunakan sistem kontrol ini fungsi kontrol proses didistribusikan pada beberapa controller individual yang menangani loop yang berbeda-beda. Miniplant workshop instrumentasi terdapat dua buah variabel pengendalian yaitu level dan flow dimana keduanya terdapat dalam satu aliran plant. Pada penelitian sebelumnya sudah dikembangkan sistem kontrol namun belum terintegrasi antara dua variabel secara bersamaan dan real time atau dengan kata lain fungsi DCS belum terpenuhi. Pada perancangan DCS miniplant workshop instrumentasi dua variabel kontrol masing-masing ditangani oleh local control unit yang dapat dikendalikan dari workstation server maupun client dan keseluruhan sistem terintegrasi dalam sebuah sistem DCS secara online dan real time. Perancangan sistem ini juga meliputi perancangan sensor DP dengan menggunakan pressure gauge dimana sudah dapat memenuhi prinsip kerja DP transmitter secara umum dengan sensitivitas 0.48 Volt.


ABSTRACT

The use of Distributed Control System as a control system usually for plant which size is very big and complicated. In process which use this sistem control is handled by some individual controllers which stand for many different loops. There are two control variable in miniplant instrumentation workshop they are flow and level. Two of them located at the same stream of process. There was a control system developed in previous final project but only for one variable. Or the other word the DCS system not implemented yet. In system that we made each control variable is handled by one local control unit which also we able to control and maintain from workstation server or workstation client in the same time and all of them integrated into one system called distributed control system . The project also include the making of differential pressure sensor use a pair of modified pressure gauges. Characteristic of sensor are same with the general DP transmitters characteristic. The sensitivity of sensor is 0.48 volt.
