Abstract :
It is obvious that hybrid propulsion ship with shaft generator system can make much better use of energy, thus with high efficiency. A novel Variable Speed Constant Frequency (VSCF) shaft generator system used on modern ship is analyzed and its structure, operational principle and control strategy are studied in this paper. The system simulation model of the shaft generator system is built in the paper and some simulation results are achieved. The simulation results show that many operation conditions of the shaft generator system, such as the synchronization, operation in parallel with the diesel generator (DG) set with good load sharing performance and splitting can be achieved successfully and stably. It is well suitable for the modern ship power system with a variety of requirements.
