摘要

Impressed current cathodic protection system is used for protecting the undergroundlong distance pipelines from corrosion. In this cathodic protection (CP) system directcurrent is applied to the pipeline which is of sufficient magnitude so as to polarize allthe anodic area. Transformer rectifier unit (TRU) /Cathodic protection power supplymodule (CPPSM) units acts as a source for the direct current (DC) power supply. Thepower supplied by the TRU/CPPSM unit will attenuate after a certain distance so thepower is supplied from either ends of all sections of the pipeline. So there will becurrent overlap in all sections of the pipeline to ensure complete protection. Theobjective of this project is to detect the amount of current overlap in each section ofthe pipeline and to develop a simulation model for determining the current overlap ineach section of pipeline. Calculations has been carried out for determining the amountof current overlap at present in three sections of the pipeline under observation andvoltage values has been suggested for reducing current overlap in the selected sectionto minimum. A power saving of about 50KW of DC power will be then achieved forremaining life of pipeline.
