摘要
为改善船舶电力系统的稳定性能,提出了在具有自动电压调节器的船舶发电机励磁系统的基础上,加入电力系统稳定器的新方法。电力系统稳定器是通过进一步控制发电机励磁系统提高电力系统稳定性能。电力系统稳定器的信号输入采用了转速、频率或电功率,从而提高了系统的阻尼,这是一种提高小信号稳定性能行之有效的方法。通过对具有电力系统稳定器的船舶发电机励磁系统稳定性的分析和仿真,得到了比较满意的效果。
To improve the stability performance of marine power system,a power system stabilizer（PSS） is introduced into the traditional marine generator excitation system with automatic voltage regulator（AVR）.The PSS uses auxiliary stabilizing signals to control the generator excitation system so as to improve the stability of the power system.Signals to the power system stabilizer are put in through shaft,terminal frequency and power,the stability of the power system is then improved by the damping of system oscillations.This proves to be a very effective method of enhancing small signal stability performance.By analyzing and simulating the stability to marine generator excitation system with PSS,better stability performance is achieved.
