FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electric engineering, in particular to technical diagnostics, and can be used for determination of inoperative generating unit (GU) in ship power plants. Technical result is achieved due to the fact that loading of each operating GU is measured, arithmetic mean value of working GU loading is calculated, determining the GU, loading of which decreases, determining deviation value of loading of this GU from the arithmetic mean value of loadings and at the moment when this value begins to increase and exceed the allowable value, the diagnosed GU is identified as inoperative.
EFFECT: reduced time for diagnosing the unit.
