Fault Diagnosis of Static Eccentricity in Marine Diesel Generators Using 2D Short-Time Fourier Transform of Three-Phase Currents [PDF]

Sensors
Static eccentricity is an important early-stage fault in marine diesel generators, as small air-gap deviations caused by misalignment or mechanical wear can escalate into bearing damage and rotor–stator contact. To address the challenge of detecting such

A Diagnostic System for Remote Real-Time Monitoring of Marine Diesel-Electric Propulsion Systems

, 2011
An innovative diesel-electric power supply and propulsion system is a highly integrated electric system consisting of power generation, power distribution, and electrical drives. Every component of this system constantly produces operating data, which is read and evaluated by several programmable logic controllers, which in turn produce control signals.
