【 摘 要 】

The paper presents an innovative method for assessing technical condition of a marine diesel engine that drives synchronous generator. It is based on the measurement and analysis of generators phase-to-phase voltage. Additionally, it requires the measurement of a pseudoperiodic signal [3] with a period equal to duration of engines working cycle. The basis for developing method was the assumption that rotational speed fluctuations of an engines crankshaft (and also the generator) depend on a course of a working process carried out in it. The generators phase-to-phase voltage is directly dependent on a rotational speed fluctuation of its rotor. It must therefore be possible to assess a course of a working process of an engine based on a voltage waveform of a synchronous generator that cooperates ogether.
