Parameter Optimization of Pipeline Cathodic Protection System Based on SSA Algo-rithm
The traditional cathodic protection system parameter design has certain experience and ran-domness,which has limitations in anode location,electropotentiometer selection,and cathodic pro-tection control.To solve the above problems,the optimal protection potential of the pipeline is deter-mined on the basis of testing the electrochemical impedance spectrum,and the influencing factors of the cathodic protection potential distribution are determined by using the secondary current distribution model in COMSOL software.The objective function of the potential distribution is determined by the uniformity and protection effect,and the iterative solution of the objective function is realized by using the Sparrow Search Algorithm(SSA).The results show that the optimal cathodic protection potential has more reference value than the protection potential interval,which can be used to improve the effect of cathodic protection.As the number of anodes increases and the applied current decreases,a stronger uniformity of the protection potential is observed.With increasing the radial distance between the anode and pipe,the positive potential shift becomes more serious,and the potential becomes more uniform.Different modification schemes are optimized according to the example,which can slow down or avoid pipeline corrosion,and proves the effectiveness and scientific nature of the algorithm.
