船舶电站同步发电机调压系统的数学模型

船舶电站电压的稳定性主要取决于同步发电机调压系统的动态特性．为了对同步发电机调压系统的过渡过程进行分析，分别建立可控相复励装置、无刷励磁同步发电机和船舶电站同步发电机调压系统的数学模型，并在此基础上分析调压系统的动态特性和同步发电机电压的变化规律．对一个实际的船舶电站同步发电机调压系统进行了计算机仿真研究，分别给出了系统在突加、突减静负荷以及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，反映了船舶电站电压的变化规律．

Mathematical model of synchronous generator voltage regulation system on ship power station

The voltage stability of a ship power station is decided by the dynamic characteristic of its synchronous generator voltage regulation system. In order to analyze the transition process of the synchronous generator voltage regulation system, the mathematical model of a controlled phase-compounding excitation unit, brushless excitation synchronous generator and synchronous generator voltage regulation system on ship power station was built.The dynamic characteristic of the voltage regulation system and the variation law of voltage can be analyzed on the basis of this. The computer simulation was made on a real synchronous generator voltage regulation system of a ship power station, giving the dynamic characteristic curves of system on suddenly applying dead load, suddenly removing dead load and starting high-power asynchronous motor respectively. The simulation results show that the mathematical model presented is reasonable and feasible, reflecting the variation law of voltage on ship power station.
