- Abstract
The cathodic protection method is the most commonly used method for pipeline anticorrosion. A current is applied to the protected structure, and the potential is negatively shifted to the protective potential range by cathodic polarization, thereby the electrochemical corrosion of the structure is suppressed. In the cathodic protection system, small distance between the anode and the structure, high resistivity of the environment medium , and high requirement for the protection current, may result in uneven potential distribution on the structure. Aiming at this problem, the parameter optimization of the system is studied by boundary element method (BEM), radial integration method (RIM) and particle swarm optimization (PSO) based on the cathodic protection potential distribution model. Then, establish a cathodic protection optimization model that meets the cathodic protection requirements and has a uniform potential distribution by optimizing the anode position and the current density.
