Application of SCADA System by Using (Fuzzy Logic Controller) on the Cathodic Protection System for Oil Pipelines.
Keywords:Impressed Current Cathodic Protection, (FLC), Pipeline, SCADA”.
This study is dedicated to design and execute Supervisory Control and Data Acquisition system
(SCADA) to monitor and control the corrosion of a pipeline buried under ground. A
microcontroller equipped with many sensors and communication system used to control and
monitor the process of an impressed current cathodic protection ICCP process for pipeline. The
combination of the hardware, was built with LabVIEW and personal computer (PC) interface
presents a “SCADA” system for two methods: Fuzzy Logic Controller (FLC) presents closed
loop, and a conventional for open loop system. Hence, under temperature of 30°C, an
assessment and comparison were carried out for two methods of controls examined at low
moisture of soil (50%) and high moisture of soil (80 %) for measuring the potential between
pipeline and anode, current, and power. It was found a decrease of (39.7%) in consumed power
when the moisture of soil changing from the low to the high level. It was attained that the close
loop (FLC) was the best method of performance, and consumption of the power.
