Abstract
Dengan kebutuhan akan listrik yang setiap tahunnya meningkat
khususnya di pulau jawa dan sekitarnya, pemerintah melalui PLN
merencanakan pengembangan kapasitas dan energi listrik guna mengatasi
meningkatnya kebutuhan tersebut. Sehingga pada tahun 2021 sistem
kelistrikan di Jawa-Bali menambahkan satu unit pembangkit Paiton 1000
MW. Dengan adanya pembangkit baru tersebut maka diperlukan
rekonfigurasi jaringan dan perlu dilakukan analisis ulang terhadap kinerja
sistem secara keseluruhan. Dari hasil simulasi menunjukkan bahwa untuk
kasus lepasnya generator, lepasnya satu saluran dan saluran dobel sirkit
tidak menyebabkan sistem keluar sinkronisasi. Karena ketika generator
lepas, daya supply yang hilang hanya 2% dari total pembangkitan dan
lepasnya saluran dapat di backup oleh sistem interkoneksi. Begitu juga
dengan kasus single pole auto reclosing dengan waktu CB kembali
tertutup sebesar 500 ms setelah gangguan, hasil respon sudut rotor,
frekuensi dan tegangan menunjukkan sistem masih stabil. Kemudian
untuk kasus waktu pemutusan kritis (CCT), nilai CCT pada sistem berada
pada kisaran 300 ms – 400 ms. Sehingga dengan standart batas pemutusan
CB untuk sistem transmisi adalah 120 ms – 140 ms maka dapat dikatakan
sistem tetap stabil ketika terjadi hubung singkat tiga fasa ke tanah.
========================================================================================================================
With demand for electricity is increasing annually, especially in
Java and surrounding areas, the government through PLN planning and
capacity development of electrical energy in order to cope with the
increasing need. So that in 2021 the electricity system in the Java-Bali
add one unit of 1,000 MW Paiton power plant. With the new power
plants will require reconfiguration of the network and should be
analysis of performance of the overall system. From the simulation
results show that for the case of loss of the generator, the loss of one
circuit and double circuit does not cause the system out of
synchronization. Because when the generator is off, the power supply is
lost only 2% of the total generation and release of line can be backup by
a system interconnect. So is the case of single pole auto reclosing the
CB time of 500 ms closed again after the interruption, response results
rotor angle, frequency and voltage indicates the system is still stable.
Then for the case of critical disconnection time (CCT), the value of CCT
on the system is in the range of 300 ms - 400 ms. So with a standard
termination CB limit to the transmission system is 120 ms - 140 ms then
we can say the system remains stable when the three-phase short circuit
to ground.
