**5.3 Conventional-PSS**

The Conventional PSS (CPSS) was designed at the nominal operating condition using the phase compensation method. The phase lag of the system was first obtained, which was found to be 20o, thus only a single lead-lag block was used for the PSS. After obtaining the phase lag, a PSS with a phase lead was designed using the phase compensation technique. The final phase lead obtained was approximately 18o, thus giving the system a slight phase lag of 2o. Once the phase lag is improved, then the damping needed to be improved as well by varying the gain *KS*. The parameters of the CPSS are given in *Table A.*1 of Appendix 8.2.3.
