Abstract
Perusahaan Listrik Negara (PLN) terus melakukan pengembangan sistem kelistrikan untuk memenuhi kebutuhan beban di Indonesia. Salah satu upaya dalam pengembangannya adalah pengembangan sistem kelistrikan Sumatera Utara. Menurut RUPTL Tahun 2025, wilayah sumatera utara akan menambah pembangkit berkapasitas 1052 MW diikuti dengan penambahan beban 2360 MVA. Pengembangan sistem kelistrikan ini dapat meningkatkan terjadinya gangguan, seperti gangguan hubung singkat yang menyebabkan pemutusan saluran secara tiba-tiba melalui rele pengaman dan circuit breaker (CB). Hal ini dapat membuat suatu sistem mengalami perubahan struktural dan mengakibatkan ketidakstabilan. Namun terkadang kemampuan rele pengaman untuk mendeteksi gangguan memerlukan waktu yang lebih lama dari Critical Clearing Time (CCT). Circuit breaker ini harus dapat memutuskan saluran dan gangguan dalam waktu yang singkat, yakni kurang dari waktu pemutus kritisnya, atau biasa disebut critical clearing time. Oleh karena itu, diperlukan suatu analisa sistem tenaga listrik untuk menentukan “Critical Clearing Time” (CCT). Hasil dari simulasi menunjukkan bahwa CCT pada titik yang dicoba berada dibawah waktu pembukaan CB, yaitu 0.3 s.
============================================================
State Electricity Company (PLN) continues to develop electrical systems to meet the needs of the load in Indonesia. One of the efforts in the development is the development of North Sumatra electricity system. According to RUPTL Year 2025, the northern region of Sumatra will add to the 1052 MW power plant followed by the addition of 2360 MVA load. The development of this electrical system may increase the occurrence of interference, such as short-circuit interference that causes abrupt disconnection through the safety and circuit breaker (CB). This can make a system undergo a structural change and lead to instability. Sometimes, however, the ability of the safety relay to detect the interference takes longer than Critical Clearing Time (CCT). This circuit breaker should be able to break the channel and interruption in a short time, ie less than the critical breaker time, or commonly called critical clearing time. Therefore, a power system analysis is required to determine "Critical Clearing Time" (CCT). The results of the simulation show that the CCT at the point tried are below the time of opening of the CB, ie 0.3 s.
