        abstract = {Osilasi sistem tenaga merupakan permasalahan kestabilan sistem tenaga dinamis.
Kestabilan sistem tenaga dinamis yang tidak diantisipasi secara dini dapat
menyebabkan terjadinya blackout. Metode Complex Morlet Wavelet Transform
digunakan untuk mendeteksi kestabilan sistem dinamis karena memiliki
kemampuan untuk melokalisir informasi waktu dan frekuensi secara bersamaan.
Pengujian metode Complex Morlet Wavelet Transform dilakukan terhadap sinyal
sistesis dengan parameter yang sudah diketahui. Hasil estimasi metode Complex
Morlet Wavelet Transform juga dibandingkan terhadap hasil perhitungan dengan
metode nilai eigen pada model Two Area Four Machine System untuk memvalidasi
metode yang digunakan.
Metode Complex Morlet Wavelet Transform digunakan untuk mendeteksi moda
interarea oscillation dan estimasi damping ratio pada sistem interkoneksi JawaBali. Dari hasil estimasi, sistem interkoneksi Jawa-Bali memiliki moda interarea
oscillation sekitar 0.5 Hz dan 0.83 Hz serta memiliki damping ratio terendah hingga
di bawah 3\%.
Kata kunci : interarea oscillation, estimasi damping ratio, complex morlet wavelet,
sistem interkoneksi Jawa-Bali, kestabilan dinamis.


Power system oscillation is a problem of power system dynamic stability. Power
systems dynamic stability that is not anticipated early can cause a blackout. The
Complex Morlet Wavelet Transform method was used to detect system dynamic
stability owing to its ability to localize time and frequency information
simultaneously. The verification of the Complex Morlet Wavelet Transform
approach was performed on the synthesized signal with known parameters. The
estimation results of the technique were also compared to the results of calculations
with the eigenvalue method in the Two Area Four Machine System model to
validate the result.
The Complex Morlet Wavelet Transform approach was used to detect interarea
oscillation mode and damping ratio estimation in the Java-Bali interconnection
system. From the estimation results, the Java-Bali interconnection system has an
interarea oscillation mode of around 0.5 Hz and 0.83 Hz and has the lowest damping
of about close to 3\%.
Keywords : interarea oscillation, damping ratio estimation, complex morlet
wavelet, Jawa-Bali interconnection system, dynamic stability.}
