A Gas Turbine Model for Hot Components Fault Detection Research
Fault detection in gas turbine hot components is generally conducted indirectly through thermo-couples at the turbine outlet measuring exhaust temperature.When analyzing the impact of various dis-turbances on exhaust temperature using gas turbine data,the limitations of actual data often prevent a comprehensive description of the effects of different factors on gas turbine parameters.Additionally,due to the high cost of gas turbines,destructive experiments to analyze the impact of faults on gas turbine pa-rameters are not feasible.To address these issues,a common solution is to establish a gas turbine model that allows flexible control of various variables,enabling experiments and effects that cannot be achieved with actual gas turbines,and reflecting the impact of typical component failures on gas turbine parame-ters.This paper presents a gas turbine model developed for hot components fault detection research.The model features multiple flame tubes and multi-turbine channel structures,taking into account the mixing and rotation of hot gases in the thermal channels.It reflects the impact of typical faults and various com-plex disturbances on the exhaust temperature distribution and analyzes the effects of different disturbances on gas turbine parameters based on the established model,providing a theoretical basis for subsequent re-search.
