Abstract

In response to the problem of poor stability of load supply in ship power supply systems when connected to the grid, this paper proposes a pre synchronization based on virtual impedance secondary control (PS-VISC) controller. The designed controller can make the transmission line equivalent to inductive characteristics to decouple power, and then suppress the impact of grid connection on ship load. In the design of the controller, secondary control and pre synchronization control are added. Compared with traditional virtual impedance controllers, this controller not only achieves power decoupling, but also solves the defect of the system output bus voltage drop caused by the addition of virtual impedance, and the shaft belt power generation system cannot smoothly switch with the ship's main network. Finally, the reliability and effectiveness of the PS-VISC controller during the grid connection process of the ship's power grid were verified through Simulink Simulation.
