Claims

[Scope of utility model registration request]

In a marine power generation system that supplies electric power generated by a marine generator to a group of loads on a ship consisting of non-important loads and other loads, a circuit that detects the amount of power supplied by the marine generator (=amount of onboard power consumption). a setter for setting the amount of power generation that can be shared by the marine generator; a comparator for comparing the magnitude relationship between the amount of power generation set by the setter and the amount of power supplied by the circuit; Based on the comparison result of the comparator, when the amount of power supplied is greater than the amount of power generated, a command is output to sequentially stop the operation of the non-important loads by the amount equivalent to the load corresponding to the amount of power generated, and the amount of power generated is equal to or less than the amount of power supplied. A false load protection device for a marine generator, comprising: a control circuit that outputs a command to sequentially restart the non-important loads by the amount corresponding to the amount of load corresponding to the amount of surplus electricity when the .
