    • Abstract
  • To analyze and improve the compatibility of regional cathodic protection system and copper grounding system in oil/gas stations, numerical simulation was used to calculate the cathodic protection (CP) effect in different anodic forms, and the effects were compared in different treatment measures. The results showed that the copper grounding near buried pipeline was the main cause of cathodic protection incompatibility. Patial or entire isolation of horizontal grounding electrodes could improve the CP effectiveness. Moreover, using electronegative materials like zinc as grounding material was an alternative option.
