This paper presents an approach for the dynamic stability anaiysis of marine power system. In most cases the marine auxiliaries are driven by electric motor. Recently diesel engines for generators have become compact by applying a high-super charging system. Momentary speed variations of the power system has been increased because small GD2 of the engine and generator rotor. It is nessesary to apply soft starting method on marine auxiliaries. When motor is started some proficient crew are used to utilize starter switch turned on and off periodically by thier experimental knowledge for stabilize electric power system. We denominates this technique as “Chopping-Start” that a method of electric motor soft starting techniques. It is presented the simplified simulation model of the turbo charged diesel engine driven generator and large capacity induction motor with load. The analytical model is shown in the form of blockdiagram and estimated by digital computer using CSMP language. Its found that the effect of “Chopping-Start” on a performance simulation model system has been studied speed and voltage regulation are smaller than use the method of line start on electric motor.
