Sažetak
The aim of this paper is to demonstrate the successful application of system dynamic simulation modelling for studying performance dynamics of the gas turbine in load conditions. This study is conducted using an example of load of synchronous generator. Gas turbine at the load of synchronous generator is a complex non-linear system, which needs to be systematically investigated as a unit consisting of a number of subsystems and elements, which are linked by cause-effect (UPV) feedback loops (KPD), both within the propulsion system and with the relevant surrounding. In this paper the authors will present an efficient application of scientific methods for the study of complex dynamic systems called qualitative and quantitative simulation System Dynamics Methodology. This methodology will allow generation and application of higher number and types of simulation models of the observed elements. Furthermore, this methodology will allow continuous computer simulation that will significantly contribute to the acquisition of new knowledge about the nonlinear characteristics of performance dynamics of turbine and generator system in the process of designing and learning. Gas turbine will be presented by a set of non-linear differential equations, after which mental-verbal structural models and flowcharts in System dynamics symbols will be produced, and the performance dynamics in load condition will be simulated in POWERSIM simulation language.
