Abstract
Batas kestabilan tegangan adalah batas maksimum tegangan sebelum akhirnya tegangan jatuh secara cepat. Metode yang digunakan adalah transfer daya maksimum dengan menggunakan reduksi impendasi thevenin. Metode transfer daya maksimum ini menggunakan imepadansi thevenin sebagai batas kestabilan, batas tersebut diambil dari resistansi dan reaktansi thevenin di dalam jaringan. Karena faktor jaringan yang berbeda jauh antara reaktansi dan impedansi, maka batas cos_phi dalam kondisi tidak baik. Oleh sebab itu dilakukan perubahan dengan cos_phi menjadi lebih baik, namun masih dalam keadaan standar. Fungsi penempatan SVC adalah untuk meningkatkan batas kestabilan. Penempatan SVC perlu dioptimal kan untuk menekan harga pengadaan. Optimalisasi menggunakan pengalian daya reaktif dan aktif secara satu persatu. Dari hasil simulasi Sistem transmisi Jawa Bali 2024 didapatkan bahwa rata-rata tengangan terendah terdapat pada bus bus 9,12,16,17, dan 18 yaitu : Duri-kosambi, Gandul, Cawang-baru, Cawang, dan Bekasi . Pemasangan kapasitor bank di bus 9,12,16,dan 17 dan pemasangan SVC pada bus 18 adalah pemasangan dengan total rugi-rugi daya terendah dibandingkan pemasangan SVC dibus terendah lainnya. Pemasangan SVC pada bus 18 dengan Bc=1.6pu mampu memperbaiki tegangan terendah yaitu 0.948 menjadi 0.950. Pemasangan SVC pada bus 18 tersebut memiliki batas kestabilan tegangan yaitu 0.556pu.

The voltage stability limits are the maximum limit of voltage before the voltage drops rapidly. The method used is the maximum power transfer using thevenin impendation reduction. This maximum power transfer method uses thevenin imepadance as a stability limit, the limit is taken from thevenin resistance and reactance within the network. Due to the much different networking factor between the reactance and the impedance, the cos_phi boundary is not in good condition. Therefore, the change with cos_phi to be better, but still in the standard state. The SVC placement function is to increase the stability limit. SVC placement needs to be optimized to reduce procurement prices. Optimization uses reactive and active power reactions individually. From the simulation result of Java Bali 2024 transmission system, it is found that the lowest average of Voltage is found in bus buses 9,12,16,17, and 18 are: Duri-kosambi, Gandul, Cawang-baru, Cawang and Bekasi. Installation of bank capacitors in buses 9, 12, 16, and 17 and installation of SVCs on bus 18 is the installation with the lowest total loss of power compared to the other lowest spliced SVC installations. Installation of SVC on bus 18 with Bc = 1.6pu able to fix the lowest voltage that is 0.948 to 0.950. Installation of SVC on bus 18 has a voltage stability limit of 0.556pu.
