Model of Gas Turbine Plant with Concentrated Parameters for Analysis of Dynamic Properties Patterns

Abstract

This article considers a model of gas turbine plants (GTPs) with concentrated parameters for analysing the regularities of the dynamic properties of transients with power changes. The main goal is to study and analyse the dynamic properties of GTPs, in particular their transients, taking into account power changes. To achieve this goal, the task is to develop a universal model based on approximation approaches using concentrated parameters. The key tasks of the article include: development of a mathematical model with concentrated parameters, which takes into account the current rated power of the GTP, investigation of the dynamic properties of the transient processes of the GTP using approximation models, obtaining an approximation dependence that shows the relationship between changes in the dynamic properties of transients and changes in the current power of the GTP. Focusing on the development of a universal model with approximation parameters provides the basis for a detailed analysis of the dynamic properties of GTPs and their behaviour at different power levels. These studies can have practical applications in improving the regulation and optimization of power systems based on gas turbine plants.
