1. A power supply system configured to couple to a power distribution bus of a marine vessel and to power a plurality of electric motors coupled to the power distribution bus, the power supply system comprising:
a generator configured to generate electric power and to provide, in operation, an output voltage at an output of the generator, the output voltage being an AC voltage; and a control system coupled to the generator and configured to control the output voltage of the generator based on a voltage setpoint, wherein the voltage setpoint, in operation, is set to an operating voltage setpoint; wherein the control system comprises:
a measuring unit configured to measure a parameter of the electric power generated by the generator, wherein a fault in a component coupled to the power supply system that results in a drop in voltage of the output of the generator is determinable based on the measured parameter; and a control unit configured to control the voltage setpoint for the output voltage of the generator based on the measured parameter, such that if a value of the parameter falls below a threshold, the voltage setpoint is reduced;
wherein the control unit is further configured to gradually increase the voltage setpoint back to the operating voltage setpoint after the fault is electrically isolated from the power supply system, thereby limiting voltage overshoot and preventing tripping of electrical components coupled to the power distribution bus of the marine vessel. |
