삼랑진 양수 1호기 PSS 정수튜닝 및 현장 성능시험

This paper deals with the parameter tuning of the PSS for a 335 MVA pumped storage power plant in KEPCO system and its validation in field test. In the paper, the selection of parameters such as lead-lag time constants for phase compensation, system gain was selected by using linear & eigenvalue analyses. Then, they were verified through the time-domain transient stability analysis. In the next step, the performance of PSS was finally verified by the generator's on-line field test.
