For reducing the operating cost of ships, the turbo generator is an effective measure for utilizing the waste heat energy contained in the exhaust gas of the main engine, which generates the electrical power required on board the ship. The parallel operation of the turbo generator and the shaft generator/motor is applied to utilize this waste heat energy of the main engine to the fullest possible extent. By applying this system, the following merits are obtained. (1) Using the waste heat energy of main engine as much as possible. (2) Operating the shaft generator/motor as the shaft motor, reduce the fuel consumption of the main engine. (3) Operating the shaft generator/motor as the shaft generator, compensate for the shortage electrical power. The energy saving shaft generator/motor control system introduced in this paper is characterized by stepless operation of the shaft generator/motor by means of the steam control valve lift, making it possible to recover the waste heat energy as much as possible.
