Abstract

Analytical studies of the results of thermal imaging control using IAS TIK together with the corresponding values of the temperature control results obtained in the standard DGS condition monitoring system were carried out within the framework of R&D for the development of an integrated automated system for thermal imaging control (IAS TIK). Approbation of IAS TIK in NPP conditions was carried out by thermography of standby diesel generator sets of NPP type 12zv40/48+S2445-12. At the same time, the parameters of the diesel engine and the generator were measured using the standard control system. The methodology is proposed that provides an analysis of the uniformity of the operation of diesel cylinders, the condition of the crankshaft bearings, the condition and quality of the generated electricity of the generator, as well as the analysis of the operation of lubrication and cooling systems. The practical application of the technique demonstrates the correspondence between the temperatures measured by the standard system and the IAS TIK. A joint analysis of the results obtained by the standard and developed systems provides an increase in the depth of the diagnostic examination and confirms the information content of the thermographic parameters and the quality of the measurement channels of the standard systems. The parameter values obtained from the analysis of the indicators of the standard control system, recorded at a steady power value, will be used in subsequent diagnostics to establish trends in these parameters
