Reliability Design and Analysis of a Low Voltage DC Network Intelligent Management System

Micro automation platform technology was applied to the naval vessel＇s electric network control system, optimizing the low voltage DC network configuration. Aiming to improve the reliability of the equipment, a series of feasible measures were taken, such as simplifying the circuit, reducing the number of components and specifications, derating design and screening of components, and devices thermal design. These measures have solved a number of deficiencies in active vessels related equipment. In order to analyze and study the reliability of the low voltage DC network intelligent management system, the block diagram and mathematical expressions of the dependencies between various parts of the device were estab- lished. And in determining the main system module components, the quantitative indicators of reliability have been allocated based on the performance.
