TRANSIENT ANALYSIS OF GAS TURBINE POWER PLANTS IN DIFFERENT CASES OF DETERIORATIONS

Abstract

Most monitoring systems of gas turbine engines based on steady state operation and diag- nostic analysis have traditionally been conducted under steady state conditions. Analysis shows that the transient operational processes have significant diagnostic content. This paper describes the mathematical models of transient operational modes of gas turbine engines, presents results of transient analysis by these models at different deteriorations. Finally the diagnostic opportunities are discussed.
