Determination of the Diagnostic System Inertial Parameters for Power Generating Station Combustion Engine

This paper presented an analytical model that describes diagnostic system of combustion engine inertial parameters for power generating station. The developed mathematical model allows to investigate moment of inertia reduction and is useful for the analysis of torque while diagnosing the power generating station on a starter current basis. These studies allowed to establish that the change in the reduced moment of inertia for one crankshaft rotates within 0,8%. Considering the insignificant influence of the inertia variable component, the given moment of a system inertia can be calculated without significant accuracy losses only as a constant component.
