A method for preventing the power failure of a power station with shaft generator by side thrust capacity reduction, first receiving the tripping signal of any one generator through the switchboard, and quickly sending the power limiting signal to the side thrust frequency converter to reduce the capacity. After receiving the capacity reduction signal, the side thrust frequency converter quickly reduces the speed. The side thrust frequency converter also monitors the DC voltage of its busbar. If the voltage drop is too large, it will also quickly reduce the speed. The specific speed reduction is triggered by the faster of the two commands. After speed reduction, the capacity is slowly increased to maintain the side thrust function to avoid affecting the safety of ship navigation. During the capacity increase process, the switchboard sends the remaining power signal of the power station. The side thrust receives the signal, gradually increases the capacity of the side thrust, and controls it within the remaining power of the power station. At the same time, the side thrust sends the side thrust power signal to the switchboard, so that the power station can accept the side thrust power in real time and update the remaining capacity of the power station, thereby ensuring the accuracy of the control.
