Abstract

The reliability of the electric power distribution system can be seen from the SAIDI number (System Average Interruption Duration Index) or long extinguished in one period and SAIFI (Sytem Average Interruption Frequency Index) or outages in one period. PT PLN (Persero) Balikpapan Area is currently trying to improve service used reliability improvement methods, namely by maneuvering the radial system network load into a loop system network and installing reclosers. Penyulang Industri 5 (I.5) for 2017 has SAIDI realization value of 7.741 hours / year, and SAIFI is 5.03 times / year. It can be interpreted that SAIDI-SAIFI 5 industrial feeders are relatively few of the value of the revised targets. This shows that industrial feeder 5 has a high level of reliability. But it still does not meet the IEEE Std standard. 1366-2000 with a SAIDI score of 2.30 hours / year and a SAIFI value of 1.45 times / year. After the improvement is obtained the value of SAIDI is almost close to the IEEE Std standard value. 1366-2000 which is 2,365 hours / year.Keywords : Reliability, SAIDI/SAIFI, Load Manuver, Recloser.

Abstract

Deaerator merupakan peralatan yang sangat penting pada pembangkit listrik tenaga uap. Deaerator berfungsi untuk menghilangkan gas-gas terlarut yang terkandung dalam air pengisi (feed wate). Level deaerator adalah parameter yang sangat penting untuk dijaga saat proses deaerari (pembuangan gas-gas terlarut). Jika level deaerator terlalu rendah, dapat mengakibatkan rusaknya boiler feed pump dan menngganggu pasokan air ke boiler, namun jika level terlalu tinggi, kandungan gas-gas terlarut seperti karbondioksida (CO2) dan Oksigen (O2) akan tinggi. Pengaturan level deaerator pada PLTU Teluk Balikpapan harus memperhatikan condensate pump discharge pressure. Pengaturan level deaerator dan condensate pump discharge pressure pada PLTU Teluk Balikpapan dilakukan dengan mengatur bukaan deaerator level control valve dan condenser recycle control valve. Penelitian ini akan memodelkan sistem kontrol self-tuning fuzzy PID controller yang disimulasikan menggunakan software MATLA-Simulink. Berdasarkan 3 pengujian yang dilakukan menggunakan 3 karakteristik gangguan yang berbeda, self-tuning fuzzy PID controller memberikan respon yang memuaskan karena berhasil menjaga level deaerator dan condensate pump discharge pressure sesuai dengan batasan operasi kedua parameter tersebut. Dari hasil 3 pengujian yang telah dilakukan, didapatkan nilai error maksimum level sebesar 6,6288 % dan Root Mean Square Error (RMSE) sebesar 20 mm sedangkan untuk error maksimum tekanan sebesaar 21 % dan Root Mean Square Error (RMSE) sebesar 0,035 Mpa.

Abstract

Abstract— PT Bukaka Teknik Utama is currently building a fairly spacious workshop building with a length of 60m, a height of 15m and a width of 20m which almost the entire building is made of steel. Considering that thunder days in the city of Balikpapan are quite high, which is as high as 227 per year, the building is vulnerable to lightning strikes. Therefore, to avoid the impact of the lightning strike effect, an external lightning protection system is needed. The method to be used in determining lightning protection is the rolling ball method. Because the shape of the building has a horse gable type the protection level is at level IV with a protection radius of 100.9m and is able to protect lightning currents up to 234.89 kA. After simulation using Sparkta software, the standard rolling ball method NFPA 780 and BS 7430 obtained detailed risk assessment calculation results which are quite safe.
