Abstract

Metode Dekomposisi Frekuensi yang didasarkan pada konsep analisis respon frekuensi dan peningkatan torsi damping akan digunakan untuk penalaan PSS pada sistem multi mesin. Dengan menganalisis respon frekuensi pada sistem multi mesin akan diperoleh diagram bode yang menggambarkan hubungan besaran dan fungsi transfer terhadap frekuensi osilasi generator dari sistem tersebut. Dari analisis tersebut akan diketahui frekuensi osilasi elektromagnetik antara generator yang terinterkoneksi. Dari frekuensi tersebut dapat diketahui (didekomposisi) frekuensi-frekuensi yang menyebabkan torsi redaman negative. Dengan demikian penalaan PSS dalam multi mesin dapat dilakukan seperti halnya penalaan pada mesin tunggal. Metode ini lebih efektif dibandingkan dengan metode lainnya seperti metoda reduksi matrik admitansi yang berdasarkan pada dominasi elemen diagonal. Untuk menunjang metoda dekomposisi frekuensi, model mesin tunggal two axis dimodifikasi untuk memenuhi kepentingan multi mesin tersebut.

Frequency Decomposition Method based on a concept of frequency response analysis and improvement of damping torque will be used for PSS tuning at multi machines system. Frequency response analysis of multi machines system can obtain the bode diagram that show the relation of magnitude and transfer function of frequency oscillation of generator from the system. Electromagnetic oscillation frequency between interconnected generators can obtained from this analysis. The decomposition of frequency will show the frequencies that causing the negative damping torque. Thereby PSS tuning in multi machine can be done as same as in single machine. This method is more effective compared with other methods like matrix admittance reduction method based on diagonal element domination. The model two axis of single machine will modified to multi machine to support frequency decomposition method.
