Abstract

Peralatan sistem tenaga seperti transformator daya memiliki umur desain yang ditentukan oleh oleh perusahaan manufaktur sehingga dapat beroperasi dalam kurun waktu tertentu. Namun sejalan dengan pemakaiannya dilapangan, umur transformator daya tersebut dapat berkurang atau bertambah dari umur desainnya. Paper ini mempaparkan perhitungan sisa umur transformator tua (aging) menggunakan pendekatan Arrhenius yang didasari oleh temperatur saat pemeriksaan lapangan dari beberapa kali inspeksi pada tahun 1982, 2013, dan 2014. Transformator yang diukur dalam studi ini memiliki rating 30 MVA dan digunakan pada lingkungan kilang gas alam cair. Berdasarkan perhitungan yang telah dilakukan, diketahui bahwa transformator tersebut masih layak untuk dioperasikan hingga 17,8 tahun lagi dengan mengikuti syarat dan ketentuan yang berlaku. Sebagai pendukung keputusan, pemeriksaan eksternal secara visual dan pengukuran earth grounding juga dilakukan. Kata kunci:

Abstract

This paper provides survey results of an electricity system that has been carried out from isolated village of Alue Keujrun, South Aceh, Indonesia. The village has a central photovoltaic power plant and a micro hydro power plant. Various problems in the field such as operation errors, lack of maintenance of the electric power system, low voltage and frequency have been found. Power plant operators have also never received any formal training from any institution. The village is located next to the Kluet river which has a very large potential to become a hydrokinetic power plant energy source. Therefore the Kluet river flow velocity was also measured during the survey and described within this paper. Based on the interviews results with local operators, the village power plant does not have an operating permit. Thus, we consider that it is important to review the types of permits required to establish a power plant in Indonesia, including small-scale power plants.

Abstract

Hydrokinetic power plants are able to produce energy only by harnessing the kinetic energy of flowing water. Compared to dam-based hydroelectric power plants, hydrokinetic power plants have minimal impact on several issues e.g. environmental, health, social and political conflict. Similar to wind turbines in a wind farms, hydrokinetic turbines in tidal farms also generate a wake effect, which results in less kinetic energy on downstream turbines compared to upstream turbines. This article shows the simulation results of three hydrokinetic power generation systems installed in series on the same water stream such as river or aqueduct. The upstream turbine generates wake effect and resulting a velocity deficit both in the two downstream turbines. Bastankhah Porté-Agel model for wake effect was used in this study. The simulation results show that the downstream turbine cannot maintain the given voltage reference and loses the stability of the power control if the water velocity decreases. Several recommendations regarding series configuration of the hydrokinetic system are also presented in order to support the control stability.

Abstract

The introductory electrical energy course is one of the courses that applies learning using practical methods. In the introductory electrical energy course, there is material about electrical power. Based on observations, it is known that students need more learning media in the form of modules in the electrical power practicum, which causes a lack of interest and low understanding of student learning. Based on these problems, a learning medium in the form of a practicum module was developed to complement practicum learning and is expected to increase students' interest in and understanding of learning. The electrical power practicum module was developed using research and development methods. The researcher's research instrument was a media expert and material expert validation sheet to test the feasibility of the practicum module to be applied in the Electrical Power Practicum. The validation results of media and material experts prove that the electrical power practicum module is very feasible regarding media and material. Based on the percentage of scores obtained from media experts, namely 81.66%, material experts obtained a score of 88.57%, which is included in the very suitable category to be applied in the Basic Electrical Energy course.
