摘要
船舶电力系统是一个非线性系统,为了对系统的过渡过程进行分析,文中建立了船舶电站柴油发电机组的非线性数学模型,该模型准确地反映了转速和电压的相互作用和相互影响的关系,体现了船舶电力系统的变量耦合性质.对一个实际的船舶电站柴油发电机组控制系统进行了计算机仿真研究,分别给出了系统在突加静负荷和起动大功率异步电动机时的动态特性曲线.计算机仿真结果表明,提出的数学模型是合理的、可行的,反映了船舶电力系统转速和电压的变化规律.
The stability of a ship＇s power system is determined by the speed and voltage response cnaracterlstic of the ship＇s diesel-generator set. A ship＇s power system is nonlinear, so to analyze the system＇s transition process, a nonlinear mathematical model of a ship＇s diesel-generator set was built. Reflected in the model was the relationship of interaction and mutual influence between speed and voltage, and the character of variables coupling in a ship＇s power system. Computer simulation was made using an actual diesel-generator set control system of a ship＇s power station, giving the dynamic characteristic curves of a system suddenly applying dead load and starting a high-power asynchronous motor respectively. The simulation results show that the mathematical model presented is reasonable and feasible, reflecting the variation law of speed and voltage of a ship＇ s power system.
