Abstract Among the various methods for generating electricity on a ship, a shaft generator system is characterized by the highest energy and economic efficiency. The use of a Permanent Magnet Synchronous Generator (PMSG) in these systems, in comparison to classic synchronous generators, improves the ship’s propulsion efficiency and the system’s reliability. The problem of adjusting the PMSG’s excitation and changing the speed of the generator’s shaft can be solved by the use of modern power and electronic systems. This article presents a method for controlling the mechatronic system of a shaft generator with a PMSG, which enables stable operation to be achieved when changing the rotational speed of the shaft. Analytical and simulation studies were carried out and have enabled the boundaries of the area in which the PMSG can operate to be determined, while maintaining the required electrical power. The results have shown that the use of a PMSG instead of an EESG can increase the energy efficiency of the shaft generator system and increases the system’s reliability.
