MATHEMATICAL MODELS OF DISTRIBUTION OF THE PROTECTIVE POTENTIAL OF UNDERGROUND MAIN PIPELINE

Аннотация

The theoretical results of research for the development of an information-analytical system for monitoring and control of electrochemical protection against corrosion of main pipelines, carried out within the framework of the grant project of the Ministry of Education and Science of the Republic of Kazakhstan AP 09261098, are presented. There are a large number of publications on the problems of electrochemical protection of underground steel structures, including main pipelines. So, in a popular form, using numerical examples, the regularities of the processes of electrochemical protection and the problems of electrochemical protection are considered as problems of currents in the ground for complex pipeline systems with inhomogeneous parameters.This article proposes stochastic models and methods for solving the problem of operational planning of operating modes of cathodic protection stations for pipelines under conditions of incomplete information when solving the problem of minimizing the cost of operating an electrochemical protection system. As a result of experimental studies of solving the problem of operational planning of the operating mode of the electrochemical protection system, the optimal values of the current strength of the cathodic protection station were obtained, under conditions of incomplete information about the resistance of the pipeline insulation coating and the resistivity of the soil, and the effectiveness of the developed models for solving this problem was shown.
