The invention belongs to the technical field of ship power systems, and discloses a simple pure battery power ship system and a working mode conversion method thereof.The power system comprises two sets of main circuit topologies of the same structure, and each set of main circuit topology comprises a direct-current busbar, a battery system, a propelling system and a daily system; the battery system is respectively connected with the propulsion system and the daily system through a direct current busbar, and the two groups of main circuit topologies are electrically connected through a bus coupler; wherein a battery cluster in the battery system adopts single-cluster power formed by large-electric-quantity monomers, a three-winding transformer is adopted in the daily system, and AC 400V and AC 230V AC busbars are not segmented, so that the continuity of power supply during AC grid-connected power supply and off-grid independent power supply mode switching of two daily DC/AC is ensured. The structure of a power system is simplified, the production cost is greatly reduced, three working modes of single-machine dragging and multi-machine cross dragging can be set, and the power supply safety of the propulsion system is guaranteed.

    本发明属于船舶动力系统技术领域,公开了一种简约型纯电池动力船舶系统及其工作模式转换方法,该动力系统包括两组结构相同的主电路拓扑,每组主电路拓扑包括直流母排、电池系统、推进系统和日用系统,电池系统通过直流母排分别与推进系统和日用系统连接,且两组主电路拓扑之间通过母联电操连接;其中,电池系统中的电池簇采用大电量单体形成的单簇动力,日用系统中采用三绕组变压器,且AC400V、AC230V交流母排均不分段,保证2台日用DC/AC进行交流并网供电、离网独立供电模式切换时供电的连续性。本发明简化了动力系统结构,大幅降低了生产成本,且可设置单机、多机交叉拖动三种工作模式,保证了推进系统供电的安全性。
