Abstract

An approach for estimating the technical state of the metal of turbines with a capacity higher than 200 MW installed at thermal power stations is described. Different methods for estimating the lifetime of turbine elements are compared with one another. A procedure for monitoring the current state and residual life of turbine main elements is proposed. A turbine decomposition procedure is carried out, and a set of parameters and technical state criteria for groups of critical elements in a turbine corresponding to these parameters are developed. Stages of estimating the current technical state of equipment are suggested. The possibility of estimating the technical state of each individual element and the turbine as a whole is revealed.
