摘要
针对船舶中压直流综合电力系统,分析系统的结构和特性。给出船舶中压直流综合电力系统的机理模型,包括原动机、发电机、推进电机和四象限负载等。在PLECS软件中建立船舶中压直流综合电力系统的仿真模型,实现了系统起动、加速和突然倒车等正常和极端工况的数字仿真,仿真结果验证了本文所进行的数字仿真研究的正确性,能够为系统的早期设计提供仿真工具。
Aiming at shipboard medium voltage DCMVDC integrated power system, the structure and characteristic of the system is analyzed in this paper. The mathematical model of the system, including prime-mover, generator, propulsion motor and four-quadrant propeller load is proposed. Then the simulation model of MVDC shipboard integrated power system is established in PLECS simulation software, and the numeric simulation of the normal and emergency operating conditions such as start, speed up and crash back is carried out. The simulation of the normal and emergency conditions for the whole system is then achieved. The simulation results validate the research of the numerical simulation for the shipboard MVDC integrated power system, which can provide simulation tools in the early design stage for the system.
