System Dynamics Simulation Model of the Marine Diesel Engine Start up System

Abstract


System dynamic simulating modelling is one of the most appropriate and successful scientific dynamics modelling methods of the complex, non-linear, natural, technical and organizational systems. Investigation of behavior dynamics of the ship/s propulsion system as one of the complex, dynamic, non-linear technical systems requires application of the most efficient modelling methods. Marine Diesel engine start up system, which it is consisted of ship/s piston compressor and its driving electric motor, i.e. in this case asynchronous motor, shall be presented in the System Dynamics modelling approach in POWERSIM simulation symbolic and language. System dynamic models are essentially continuous models since the realities have been demonstrated by a set of non-linear differential equation, i.e. “equations of conditions”, however they are at the same time discrete ones because their principle time interval calculation i.e. (discretisation) sampling “DT” is determined in full compliance with (Sampling Theorem) by Shannon and Koteljnikov.
