Abstract
The aim of this paper is to present the successful application of the system dynamics simulation modelling in the research carried on the performance dynamics of the marine steam turbine in load conditions, and in this very example at load of a marine synchronous generator. The marine steam turbine at load of a synchronous generator is a complex non-linear system, which needs to be systematically researched into as a unit consisting of a number of subsystems and elements, which are linked by cause-effect (CE) feedback loops (FBL), both within the propulsion system and with the relevant environment. The authors of this paper aim at presenting the efficient application of the scientific methods used in the research of the complex dynamic systems called System dynamics qualitative and quantitative simulation methodology, which will make the production and use of a larger number and a variety of simulation models of the observed elements possible, thus enabling the continuous computer simulation, which will significantly contribute to the acquisition of new information about the non-linear character of the turbine and generator system performance dynamics in the designing and education process. The marine steam turbine will be presented by a set of non-linear differential equations, after which mental and verbal structural models and flowcharts in the System dynamics symbols [1 and 2] will be worked out, and the performance dynamics in load conditions will be simulated in the POWERSIM simulation language [5].
