To improve the stability performance of marine power system, a power system stabilizer (PSS) is intro-duced 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 sys-tem. 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 excita-tion system with PSS, better stability performance is achieved.
