Abstract
Kebutuhan energi listrik terus meningkat seiring dengan kemajuan teknologi dan bertambahnya populasi manusia. Energi listrik banyak dibutuhkan masyarakat yang tinggal di daerah maupun di kota. Penggunaan energi listrik untuk kebutuhan fasilitas sumber listrik baik skala kecil maupun skala menengah keatas, sumber energi listrik yang ada di Pulau Lombok ini terus meningkat terutama suplai dari aliran listrik melalui pembangkit dan disalurkan melalui jaringan transmisi dan didistribusikan melalui saluran distribusi sehingga listrik sampai ke pelanggan. Penelitian analisis aliran daya adalah untuk memperoleh informasi mengenai aliran daya atau tegangan pada suatu jaringan sistem tenaga listrik. manfaat dari analisa aliran daya listrik adalah untuk mengetahui kondisi keseluruhan dari suatu sistem tenaga listrik apakah masih memenuhi batas-batas yang telah ditentukan serta untuk mengetahui besar losses yang ada. Dan analisis hubung singkat bertujuan untuk mengetahui berapa besar arus kontribusi tiap cabang saat gangguan hubung singkat. Dengan analisis hubung singkat ini, dapat dijadikan dasar untuk penentuan rating circuit breaker yang akan digunakan sebagai pengaman dan dapat juga digunakan untuk penentuan setting relay. Hasil simulasi menunjukan nilai profil tegangan sistem diatas nominal tegangan dan masih dalam batas range Standar PLN No 1 Tahun 1995 dimana sebesar -10% dan +5% dari nominal tegangan, dan losses sistem yang didapatkan semakin meningkat dengan bertambahnya beban pada sistem. Kemudian untuk arus hubung singkat didapat nilai arus lebih besar seiring bertambahnya juga jumlah beban pada sistem dan arus masih dalam batas aman dikarenakan masih dibawah 40 kA.

The need for electrical energy continues to increase along with technological advances and the increasing human population. Electrical energy is much needed by people who live in regions and cities. The use of electrical energy for the needs of electricity source facilities both small scale and medium scale to the top, the source of electrical energy on the island of Lombok continues to increase, especially the supply of electricity through the power plant and channeled through the transmission network and distributed through distribution channels so that electricity reaches customers. Load flow analysis research is to obtain information about the flow of power or voltage on an electric power system network. The benefit of power flow analysis is to find out the overall condition of an electric power system whether it still meets the predetermined limits and to find out the amount of losses that exist. And short circuit analysis aims to find out how much the contribution current of each branch during a short circuit fault. With this short circuit analysis, it can be used as a basis for determining the circuit breaker rating that will be used as a safety and can also be used for determining relay settings. The simulation results show the value of the system voltage profile above the nominal voltage and is still within the range of PLN Standard No. 1 of 1995 which is -10% and +5% of the nominal voltage, and the system losses obtained are increasing with increasing load on the system. Then for the short circuit current, the current value is obtained greater as the number of loads on the system increases and the current is still within safe limits because it is still below 40 kA.
