Tuning of Dual-input PSS and Its Application to 612 MVA Thermal Plant: Part 2-Field Testing and Performance Verification

다중입력 PSS 튜닝 방법과 612 MVA 화력기 적용: Part 2-현장 튜닝시험 및 성능검증

  • Published : 2009.04.01


The second paper, Part 2, describes the field testing of IEEE type PSS2A EX2000 excitation in the Dangjin 612 MVA T/P #4. The final PSS gain, $K_s$, was determined by inputting 2%-step signals into AVR at a loading of 500MW and increasing $K_s$, from 0 to 15 in increments of 3. After the field testing, the measured data was also analyzed by Discrete Fourier Transformation(DFT) analysis, and the model parameters of generation system were verified by replicating the measured data with the transient stability program.
