| Abstract: | A PSS(Power System Stabilizer) parameter optimization method is proposed,which determines the time constants of PSS phase compensation to meet the requirement of unit compensated phase characteristics in low frequency band and tunes the PSS control gain based on critical margin method to obtain the minimum oscillation of unit electromagnetic power.The maximum-minimum ant system is used to solve the optimization model.It is based on the unit uncompensated phase characteristics measured on site.The PSS parameters of some units in Southern China Power Grid are checked and tuned by the proposed method,which verifies its effectiveness. |
