摘要
船舶电站频率的稳定性主要取决于柴油机调速系统的转速响应特性。为了提高柴油机调速系统的动态精度 ,本文采用了双脉冲调速器 ,建立了柴油机双脉冲调速系统的数学模型 ,并对其进行了计算机仿真研究。计算机仿真实验结果表明 ,双脉冲调速器能够有效地提高调速系统精度和抑制负荷扰动的能力。
The frequency stability of a shipboard power station is decided by the speed response characteristics of its diesel engine speed governing system.In order to improve the dynamic speed governing precision,double-pulse speed governor is generally used.In the paper,a mathematical model of a diesel engine double-pulse speed-governing system is established and computer-simulated.The simulation results show that the double-pulse speed governor improves precision of the system and its ability to depress load disturbance.
