Abstract  With the development of the ship's integrated power system, the power supply of low-voltage equipment can be guaranteed through connecting the inverter and the auxiliary generator of the ship by the ship power dispatching center. In order to ensure the stability of low-voltage power grid during the power supply switching process, the inverter and alternator of the ship's integrated power system are connected to the grid. Combined with the control strategy, the inverter and generator are controlled through the energy management system, which solves the problem of stable control and power distribution in the process of connecting the marine inverter with the auxiliary generator. Through the 11 prototype physical experiment, the effectiveness and reliability of the control strategy are verified.
