摘要
The invention relates to the field of engineering, and more particularly to a method for assessing the remaining useful life of the first stage of a gas turbine assembly. The present invention can be used in the creation, use, control and monitoring of a variety of different systems, including complex technical systems with integrated gas turbine assemblies used in power generation, mechanical engineering, public utilities and other fields. The present invention addresses the problem of creating a method for assessing the remaining useful life of the first stage of a gas turbine assembly which would make it possible to determine the remaining useful life of the first stage of a gas turbine assembly on the basis of measurements of the actual temperature upstream of the first stage of the gas turbine, overtemperatures upstream of the first stage of the gas turbine (the difference between the actual and a theoretical temperature), bending stresses in the rotor blades of the first stage of the gas turbine, and other significant factors. By comparison with methods known to the applicants, the claimed method provides maximum universality and flexibility and makes it possible to achieve better results. In particular, it makes it possible to objectively and automatically determine the remaining useful life of the first stage of a gas turbine assembly.
