| Abstract (English): |
In order to guarantee the stability of the ship grid，this paper studies the working principle of the Z source inverter and the control strategy of the ship shaft generator grid-connected system. A Z-source inverter was studied and it was applied to the grid-connected system of the ship shaft generator. This Zsource inverter provided features that cannot be obtained in the traditional inverter. It effectively solved the defects of the traditional topological circuit structure. At the same time LCL filter was used in the power grid side. To avoid the use of the new current sensor，the active damping was obtained by the lead-lag network to suppress the resonance of LCL filter. The grid-connected current was fast tracked and the reliability of ship power system was greatly increased. Finally the correctness is verified by the simulation and experimental analysis.
