ABSTRAK

Stabilitas frekuensi adalah hal yang sangat penting dalam sistem tenaga listrik. Pada sistem kelistrikan skala besar Jawa-Bali stabilitas frekuensi harus dijaga beroperasi pada nilai nominal 50 Hz. Peristiwa lepas pembangkit atau pembangkit yang gagal masuk ke dalam sistem interkoneksi ketika beban puncak dapat menyebabkan penurunan frekuensi sistem tenaga listrik. Kondisi tersebut terjadi karena adanya ketidakseimbangan antara pembangkitan dan beban. Selain berpengaruh terhadap turunnya frekuensi Tegangan juga akan ikut berpengaruh sehingga dapat menyebabkan padam total. Oleh karena itu Diperlukan pola mekanisme load shedding yang tepat dan benar untuk mencegah penurunan frekuensi sistem. Pada penelitian ini memiliki tujuan untuk menentukan titik optimal dan besar efisiensi load shedding yang tepat dari sistem kelistrikan Jawa-Bali menggunakan metode sensitivitas untuk mencegah voltage collapse. Hasil penelitian menunjukkan bahwa jumlah pelepasan beban menggunakan metode sensitivitas bus 8.57 lebih sedikit dari standar yang digunakan oleh PLN.


ABSTRACT

Frequency stability is very important in power system. In the Java-Bali power system frequency stability must be maintained to operate at a nominal value of 50 Hz. Generator outage or failure of the generator which is connected to the interconnected system when peak loads can cause a decrease in the frequency of the power system. This condition occurs because of an imbalance between generation and load. Besides effect on the decrease frequency voltage will also be affected so that it can cause black out the system. Therefore the exact pattern of load shedding is needed to prevent a decrease in the frequency of the system. In this researchthe objectivesare to determine the optimal point and the efficiency of load shedding at electrical Java-Bali power system using sensitivity method to prevent voltage collapse.Research results shows that using sensitivity methodthe load shedding amountis 8.57 less than PLN standard.
