船舶电力系统建模

分析研究船舶电力系统的安全性可以运用系统故障仿真手段，但必须对船舶电力系统精确的数学模型进行建模。从某大型集装箱船舶电力系统的工作原理出发，根据柴油发电机组的动态特性，研究了船舶电力系统模型的结构和原理，建立了船舶电力系统模型，该系统可以仿真船舶电力系统的许多运行工况。给出了发电机组正常起动过程和滑油泵、侧推器先后起动时滑油泵电缆发生三相接地故障的仿真过程，对电力系统的参数整定和安全策略的选取有一定的参考价值。

Modeling of Marine Electric Power System

The simulation of electric power system failure can be used to analyze and investigate safety of marine electric power system, but it has to be based on an accurate mathematical model of marine electric power system. According to the working principles of marine electric power system in a large container ship and the dynamic characteristics of diesel generator, the structure and principle of this model is studied and the model is established. This system can simulate many operating conditions of marine electric power system such as the process of diesel generator set starting, the process of three-phase ground failure when lubrication oil pump starting and after that side-thruster starting. These simulation results are useful for parameter setting and safety strategy selecting of electric power system.
