A shaft generator system is widely used in a ship to provide sufficient power for the electric apparatus by using a part of the power produced by the main engine. We have already analyzed the steady-state characteristics and open-loop transient performances of the system. In this system, the output voltage and frequency should be kept constant. Hence, the closed-loop control systems for constant voltage and frequency of the system need to be investigated.<br>In this paper, transient performances of the shaft generator system for the case with closed-loop control system are analyzed first. The effects of the duplex reactor for eliminating the output voltage distortion and the controller constants of the system on the transient performances are clarified. Also, experimental transient responses are compared with simulated results. In order to give generality to the results, average constants of the shaft generator system are used in the investigation and the transient responses of the system with these constants are simulated. It is clarified that although the transient responses become oscillatory for the case with basic closed-control system, the responses are improved remarkably when the current minor-loops are incorporated into the system.
