“…However the mentioned approach is suggested to reduce the PL, the voltage profile improvement cannot reach a satisfactory level at the tail end due to conductor physical limitations. Another solution is proposed to convert the LV system in DN to an MV system, including transformers and lines [27]. This approach is applicable to conventional DN and does not require updating the control of the power grid.…”

Usually, rural areas can be electrified via three-phase distribution transformers with relatively large capacities. In such areas, low voltage lines are used for long distances, which cause power losses and voltage drop for different types of consumers. Reducing losses and improving voltage profiles in rural distribution networks are significant challenges for electricity distribution companies. However different solutions were proposed in the literature to overcome these challenges, most of them face difficulties when applied in the conventional distribution network. To address the above issues, an applicable solution is proposed in this paper by installing a number of small-capacity distribution transformers instead of every single large-capacity transformer in rural areas. The proposed approach is implemented in the branch network of Al-Hoqool village, which belongs to the Nineveh distribution network. The network has been inspected on-site, drawn, and analyzed using the electrical systems analysis program (ETAP). The analysis showed that using the single-phase pole-mounted transformers can improve the voltage in the network's end by 29% and enhance the voltage profile for all consumers. The analysis has also demonstrated that the modification can reduce the total power losses by 78% compared to the existing network. Concerning the economic aspect, the payback period for the proposed network is assigned to be 20 months.

“…Cara yang dapat dilakukan untuk mengurangi rugi-rugi daya ini dapat dilakukan rekonfigurasi jaringan diantaranya dengan merubah diameter penghantar, memasang transformator sisip dan memasang kapasitor bank menggunakan bantuan perangkat lunak ETAP [10][11][12][13]. Analisis aliran daya dalam mengetahui rugi-rugi daya yang terjadi dapat dilakukan dengan menggunakan beberapa metode yaitu metode Gauss-Seidel, Metode Newton-Raphson dan Metode Fast Decouple [14][15][16].…”

Gardu induk merupakan salah satu bagian penting dalam sistem transmisi menjadikan gardu induk ini harus sangat diperhatikan karena jika terjadi kegagalan operasi pada gardu induk maka akan terjadi pemadaman bagi konsumen. Banyak cara yang dilakukan agar keandalan penyaluran tenaga listrik tetap terjaga. Berdasarkan hal tersebut pada sistem distribusi, efisiensi dapat dilakukan salah satunya dengan meminimalisir jatuh tegangan (drop voltage) pada saluran dan mengurangi daya reaktif yang terjadi. Tujuan penelitian ini untuk mengetahui aliran daya yang dibutuhkan trafo daya untuk mensuplai penyulang dengan rugi-rugi daya yang diperbolehkan. Serta mengetahui berapa besar rugi-rugi daya yang terjadi dan perubahan rugi-rugi daya sebelum dan sesudah perbaikan. Metode Newton-Raphson akan digunakan untuk menganalisis aliran daya pada sisi penyulang Gardu Induk Denai. Hasil pengukuran rata rata Arus beban puncak pada sisi penyulang trafo daya I dan trafo daya II adalah 1159 A dan 644 A. Cara yang dilakukan untuk mengurangi rugi-rugi daya pada sisi penyulang Gardu Induk Denai dengan mengerubah luas penampang penghantar yang di bantu perangkat lunak ETAP. Hasil penelitian rugi-rugi daya pada saluran penyulang trafo daya I dan Trafo daya II Gardu Induk Denai adalah sebesar 51,58 kW dan 25.381 kW. Setelah dilakukan perbaikan maka rugi-rugi daya yang dikurangi sebesar 30,89 kW. Perbaikan luas penampang kabel merupakan salah satu acara yang efisien untuk mengurangi rugi-rugi daya pada saluran.
