Abstract
The monitoring of electrical insulation resistance is one of the most important parameters characterizing the reliability of the on-board electric-power system and the safety of its operation. A significant part of the faults and failures inherent in elements of the shipboard power system is associated with reducing insulation electric resistance with respect to the ship hull caused by exposure to high humidity and temperature, as well as mechanical damage to the insulating layer, electrical cables, wires, and electrical devices. The rules of technical operation establish the lowest values of insulation resistance of the elements of the onboard electric-power system with respect to the ship hull. At the same time, the presence of highly branched electrical networks on the ship complicates the problem of centralized and localized insulation resistance monitoring. In addition, the increase in the number of power plants and possible changes in the number of concurrent consumers within the power system, as well as an increase in the contribution of high-voltage electrical onboard equipment, requires a more reliable control system for electrical insulation resistance. The author concludes that, to provide more reliable insulation resistance monitoring of the elements of an onboard power system, it seems relevant to additionally use novel principles and methods for controlling the measurement information in the monitoring system and processing this information, which differ from those traditionally used in the construction of such systems. For this purpose, as well as to improve the characteristics of the insulation resistance monitoring of the electric-power system, it has been proposed to apply the queuing theory with the assessment of its parameters. The onboard presence of a system for the continuous automatic monitoring of insulation resistance is an important component that provides the reliability and safety of ship operation by its crew.
