Austria VATECH ELIN's THYNE6 excitation PSS model widely applied in pumped storage power station in China and IEEE Std 421-PSS 2A's PSS model are compared and analyzed. Introduction, analysis and computation are done for Zhaoshi power plant #1 generator and Heimifeng power plant #4 generator. These include PSS parameter setting test process, reactive compensation test data, simulation angle and frequency data and setting of generator PSS test wave diagram. Contrast computation is conducted for computation parameter selection of a/p PSS simulation computation software and the damping ratio of generatiors before and after Heimifeng #4 generator simulation. The simulation computation software is developed successfully, which provides powerful means for PSS on site parameter setting test
