| Abstract: | The verified method and results of the excitation system model of 600 MW generator in Jiaxing Power Plant were presented. The parameters of power system stabilizer (PSS) for the excitation system were set by using online frequency response analysis method. The test results show that the post-setting parameters of PSS possess good adaptability, and the PSS can effectively suppress the low frequency oscillation within the frequency range from 0.2 Hz to 2.5 Hz, and possess good damping action. Then, Prony analysis was also carried out to prove that the PSS is effective to improve the damping of local oscillation mode. |
