A damping analysis method for power system stabilizer (PSS) based on transient circuit is proposed. The transient equivalent circuit of sixth order generator model and its energy function is obtained According to circuit theory, the damping of excitation system is analyzed. Based on the analysis, a PSS damping evaluation method is proposed. The simulation results of a single machine infinite bus system show that the proposed method can accurately evaluate the damping of PSS.
