Keandalan sistem tenaga listrik merupakan salah satu isu utama dalam penyaluran energi listrik. Gangguan berulang pada jaringan distribusi energi listrik sangat mempengaruhi keandalan sistem distribusi. Tujuan dari studi ini adalah meningkatkan keandalan sistem distribusi tenaga listrik dengan melakukukan pemasangan recloser pada jaringan distribusi. Recloser merupakan pengaman yang berfungsi untuk memisahkan daerah yang terganggu sehingga dapat memperkecil daerah yang terdampak gangguan. Pada Penyulang Olak Alen terdapat 2 buah recloser yang terpasang pada bus 5 dan 6 dengan indeks keandalan SAIDI 6,0544 jam/tahun dan SAIFI sebesar 1,8724 gangguan/tahun berdasarkan data pada tahun 2019. Pada penelitian ini posisi recloser dioptimalkan dengan algoritma differential evolution (DE) agar keandalan sistem distribusi lebih baik. Berdasarkan simulasi, penempatan recloser untuk 2 buah recloser terletak pada bus 5 dan 13 dengan indeks keandalan SAIDI 4,5461 jam/tahun dan SAIFI 1,3904 gangguan/tahun. Penempatan posisi recloser saat 3 buah terletak pada bus 8, 13 dan 21 dengan indeks keandalan SAIDI 4,0095 jam/tahun dan SAIFI 1,2272 gangguan/tahun. Dari hasil studi tersebut disimpulkan bahwa penempatan recloser menggunakan algoritma DE lebih optimal dibandingkan cara konvensional. Kemudian, semakin banyak recloser yang dipasang, maka keandalan sistem distribusi akan semakin meningkat.

“…Conducting a comprehensive examination of both symmetrical and unsymmetrical faults is essential to ascertain the quantity of fault currents and determine the fault Kilovolt Ampere (KVA) or Megavolt Ampere (MVA) for each type of fault. Such analysis aids in establishing appropriate ratings for circuit breakers utilized within the power system [2]. This research aims to investigate the fault MVA resulting from symmetrical or unsymmetrical faults at any specified place of interest.…”

This research paper investigates the major issue of power transmission line faults in electrical engineering. Through advanced simulation tools such as MATLAB and ETAP, the study aims to comprehensively analyze various fault circumstances, including symmetrical and unsymmetrical faults, to determine fault Kilovolt Ampere (KVA) or Megavolt Ampere (MVA). Through detailed fault analysis, insights are sought into improving the reliability and efficiency of power transmission networks, consequently minimizing risks of property damage, casualties, and economic disruptions.

Reliability performance, especially the lower confidence limit of reliability, plays an important role in system risk and safety assessment. A good estimator of the lower confidence limit of system reliability can help engineers to make the right decisions. Based on the lifetime of the key component in a typical satellite intelligent power distribution system, the generalized fiducial method is adopted to estimate the lower confidence limit of the system reliability in this paper. First, the generalized pivotal quantity and the lower confidence limit of reliability for the key component are derived for the lifetimes of the exponential-type and Weibull-type components. Simulations show that the sample median is more appropriate than the sample mean when the lower confidence limit of reliability is estimated. Moreover, the lower confidence limit of reliability is obtained for the typical satellite intelligent power distribution system through the pseudo-lifetime data of the metallic oxide semiconductor field effect transistor. The lower confidence limit of reliability for this power distribution system at 15 years is 0.998, which meets the factory’s reliability requirement. Finally, through the comparison, a hot standby subsystem can be substituted with a cold standby subsystem to increase the lower confidence limit of the system reliability.
