FIELD: electricity.
SUBSTANCE: invention relates to a system for adaptive control of cathodic protection stations along the laying of an underground metal pipeline. System contains controlled power modules, adjustable setters of protective potential value, comparison electrodes, comparison units, load sensors, communication lines, cathodic protection stations control module, potential data collection units, cathodic protection stations load collection, cathodic protection stations adaptive control, cathodic protection stations load setting unit, potential and load display units along the underground metal pipeline, a potential memory unit, a timer, a data sampling unit, units of adaptive correction of protective potentials, switches and comparators of excess loads of cathodic protection stations. Outputs of the communication line of the module for controlling cathodic protection stations from additional comparison electrodes of remote and controlled points of the pipeline through the communication line of the cathodic protection station are connected to inputs of the data collection unit of potentials of remote and controlled points of the pipeline.
EFFECT: increased efficiency of protection against corrosion by means of uniform maintenance of value of protective potential and load of cathodic protection stations along length of underground metal pipeline.
