Abstract: Introduction was made to a new type port coastal power system for the ships and analysis was made to IT system insulation monitoring method of neutral conductor. Combined with the system insulation resistance measurement method based on the DC signal injection, this paper raised the method that carried out merging and judgment to the system monitoring data by applying selforganizing mapping network (SOM). Actually measured data simulation and engineering application of the test system proves the feasibility of application of SOM network insulation fault monitoring method in IT system.
         Key words: IT system; self-organizing mapping network; fault detection; neutral conductor
