航天测量船电力系统稳定性的仿真研究

Simulation and Study on Stability of TT&C Ship Power System

以某航天测量船为例,分析了其电力系统的结构和组成,基于MATLAB/Simulink软件建立了柴油发电机组和不同类型负载的仿真模型,进而构建了该船的电力系统仿真模型。利用模型仿真分析了海上航行工况下负载顺序启动对电力系统稳定性的影响,得到了柴油发电机组和负载的运行波形。仿真结果表明,不同负载类型对稳定性的影响是不同的,负载功率越大对稳定性的影响也越大。利用该模型可以对其他工况下电力系统稳定性进行分析,也可以为测量船电力系统的分析和设计提供参考。

This paper analyzes the structure and composition of a TTC ship power system. Based on MATLAB/Simulink software, the models of the diesel generator set and different types of loads are created before the simulation model of the whole ship power system is constructed. The impacts on power system stability caused by loads startup are simulated under the sailing condition. The running waveforms of the diesel generator set and the loads are given by the simulation model. The results show that different kinds of loads cause different impacts on the stability, and the impacts increase with the load power. The model can be used for analyzing the stability under other conditions, and also provides a reference for analyzing and designing the TTC ship power system.
