PROBLEM TO BE SOLVED: To provide an electric propulsion ship control device, an electric propulsion ship control system, and an electric propulsion ship capable of changing a ship speed without using an inverter or a variable pitch propeller, and starting an induction motor without particularly excessively increasing a start current.SOLUTION: An electric propulsion ship control device includes: synchronous generators 20a and 20b driven by motors 10a and 10b, respectively, the numbers of revolutions of which can be regulated by number-of-revolutions control means; excitation regulators 62a and 62b regulating excitation voltages and/or excitation currents applied to the respective synchronous generators 20a and 20b; and induction motors 30a and 30b to which propellers 40a and 40b driven by electric power generated by the synchronous generators 20a and 20b are connected, respectively. A first generation control mode for controlling generation voltages of the synchronous generators 20a and 20b by causing the number-of-revolutions control means to regulate the numbers of revolutions of the motors 10a and 10b, respectively, and a second power generation control mode for controlling the generation voltages of the synchronous generators 20a and 20b only by causing the excitation regulators 62a and 62b to regulate the excitation voltages and/or the excitation currents, respectively are executed to be linked with each other.
