Abstract

YSP PUSRI Senior High School  is a school under the auspices of the Yayasan Sosial Pendidikan Pupuk Sriwijaya. The average students of this school come from the upper middle class. Therefore, most of the students are very familiar with all the ease of activities and comfort because they supported by a variety of electronic equipment. In addition, as a Adiwiyata winning school in the province of South Sumatra, this school implements a Green Ecology policy by using solar cells as an energy source for lighting. On the other hand, students' awareness of the importance of saving electricity is still low. For them, saving electricity is synonymous with reducing their comfort and pleasure. Therefore, with this condition it is deemed necessary to conduct extension activities in order to provide knowledge to students, about how to use and maintain safe and economical electrical equipment and how to apply energy solar cells as an effort to maintain the sustainability of electrical energy in Indonesia

Abstract

Voltage instability is considered one of the primary sources of insecurity in power systems. Voltage instability is the phenomenon in which the voltage on the receiver's side is dropping far below the normal value and does not return even after establishing a voltage recovery mechanism, or continue to oscillate due to lack of attenuation. In this study, there will be a voltage stability analysis on the power system in several phases by conducting a power flow analysis, static voltage stability analysis using continuous power flow method, and dynamic voltage stability analysis using the time-domain analysis. The power system tested on this research is the IEEE 6 bus system from Wood Wollenberg, with the software used for the simulation, which is PSAT. The results show that voltage stability analysis using Continuous Power Flow and Time Domain Analysis can provide a more comprehensive overview of a power system stability level.  The highest decrease in voltage with a value of 1.5% appears in Bus 5 which is also suffering the lowest stability level. The system has a load margin (λ) value of 1.6130 a clearing time of under 0.4 seconds

Abstract

Jaringan SUTM seringkali mengalami gangguan petir tak langsung berupa sambaran induksi . Hal ini disebabkan tingkat ketahanan impuls isolasi V50% dari isolator SUTM relative rendah. Untuk itu kawat ditempatkan pada jaringan untuk perlindungan. Efektifitas perlindungan kawat tanah dinyatakan sebagai faktor perisaian yang didefinisikan sebagai hasil bagi tegangan induksi dengan kawat tanah dan tegangan induksi tanpa kawat tanah.Tujuan penelitian ini adalah untuk mengetahui tingkat efektifitas kawat tanah dalam melindungi kawat saluran pada SUTM 20 kV di Gardu Induk Boom Baru. Dari hasil perhitungan dan analisa bahwa nilai faktor perisaian kawat tanah di Gardu Induk Boom Baru sudah cukup efektif, karena mampu mengurangi jumlah gangguan petir induksi sebesar 35,50 gangguan per 100 km per tahun
