Problems of Improving the Diagnostic Systems of Marine Diesel Generator Sets

The problem of transition from marine diesel-generator sets operation by the assigned useful life to that by their technical condition is considered. This Article includes a review of control and diagnostic systems of marine diesel-generator sets, establishes their features, analyzes the methods of trend control used and shows their identified shortcomings. A regression statistical model linking the temperature conditions and the load change is offered. The trends of deviations of time series of the temperature condition recorded parameters data from the statistical model in marine diesel generator sets long operation are analyzed. It is proposed to improve the methods of trend control and analysis for use in the systems of technical diagnosing of marine diesel generator sets, in order to increase their efficiency by taking into account the natural wear-and-tear.
