Abstract

This research examines how load variations affect the performance of a pico-hydro power system, specifically focusing on voltage, current, frequency, and generator speed. Experiments were carried out through direct measurement under different load conditions. The findings reveal that as the load increases, the output voltage decreases due to higher circuit resistance, while the output current rises significantly. The generator frequency remains relatively stable under light loads but starts to fluctuate near full capacity, indicating the need for improved regulation. Similarly, the generator’s rotational speed declines with higher loads, signaling a performance limit. These results highlight the critical relationship between load changes and system performance, providing valuable insights to enhance the efficiency and stability of pico-hydro systems, especially for renewable energy applications in remote areas.

Abstract

This article discusses the performance analysis of solar power plants for public facilities reviewed from a techno-economic perspective using the Homer application. The research location in this article is the public facility of Surau Nur Jannah in the Puncak Labuang Limau Manis Tourism Area, Padang City. Based on field visits, the community conveyed the limited resources related to the development of the tourism area, one of which is the availability of electrical energy. Based on the problems conveyed by the community, Padang State Polytechnic through the Department of Electrical Engineering provides a solution to the problem of limited electrical energy sources, by offering the concept of Renewable Energy. The initial stage of providing electrical energy sources is to build an Off-Grid Solar Power Plant with a capacity of 240 WP. In order to support the construction of the Solar Power Plant at the specified location, it is necessary to conduct a performance and economic analysis of the development. This location has a fairly large potential for solar resources, on average in one year this place receives solar radiation of 4.91 kWh/m3/Day. The most optimal configuration from the simulation results is a combined system, two units of 1 kW Generic Photovoltaic, Converter, Storage / Battery. The production of electrical energy with this configuration obtains 39.6 kWh/year of electricity with a total consumption in one year of 29.2 kWh/year. The results of the analysis of the power plant's performance from a techno-economic aspect provide positive results, with a Cost Of Energy (COE) of Rp. 1,095.34/kWh. This article aims to provide an understanding of the construction of small-scale power plants for public facilities with minimum costs

Abstract

Community service program for lecturers in the Department of Electrical Engineering, in order to fulfill the Tridharma of the Padang State Polytechnic College (PNP) for the 2024 fiscal year. The activity carried out is the installation of an Off Grid Solar Power Plant (PLTS) at Surau Nur Jannah in the Puncak Labuang tourist area Sweet Limau Padang City. Based on the Limau Manis sub-district planning analysis document for the next five years, one of the potentials that will be developed to improve the community's economy is to make the Puncak Labuang area a glamping/camping ground tourism area, farming education with an environmentally friendly concept. Currently, the development of this tourist area is carried out independently by the community by working together, such as building a prayer room. Based on the results of field visits and meetings between the PNP thematic service team and the community, on that occasion the community expressed complaints about limited human resources related to the development of the Puncak Labuang tourist area. Some of the issues raised include graphic design, spatial planning, governance, the need for clean water and the availability of electrical energy. PNP, through its community service activities, helps find solutions to solve problems in the Puncak Labuang tourist area by involving all departments in the PNP so that the Puncak Labuang tourist area can be known and visited by tourists.

Abstract

Pembangkit Listrik Tenaga Mikrohidro (PLTMH) merupakan salah satu solusi energi terbarukan yang banyak diterapkan di daerah terpencil. Namun, sistem ini memiliki kelemahan berupa fluktuasi tegangan akibat perubahan beban konsumen secara tiba-tiba. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem pengatur beban otomatis berbasis mikrokontroler dengan kontrol Proportional Integral Derivative (PID) untuk menjaga kestabilan tegangan keluaran generator mikrohidro. Perubahan tegangan keluaran sebuah generator dipengaruhi oleh salah satu faktor yaitu pengaturan penggunaan beban. Dalam penelitian ini dibuat suatu sistem pengatur beban otomatis (ELC/Electronic Load Controller) pada generator sinkron 1 fasa untuk menjaga kestabilan tegangan generator sesuai ratingnya sebesar 220 Volt. Mengimplentasikan kontroler PID untuk menstabilkan tegangan terminal pada generator sinkron 1 fasa. Hasil pengujian menunjukkan bahwa sistem dengan kontrol PID mampu menstabilkan tegangan keluaran pada nilai 220 V ± 1%. Dibandingkan dengan sistem tanpa control ELC, selisih tegangan berkurang hingga 80%. Berdasarkan hasil tersebut, kontrol PID terbukti efektif dalam menjaga kestabilan tegangan pada PLTMH skala kecil, serta berpotensi diterapkan pada sistem pembangkit terbarukan lainnya.
