Abstract

The need for electrical energy is a necessity that can not be ditawar–tawar anymore for a life worthy of every person in this day. Generally, remote rural areas located in mountainous areas have a large potential of water energy, so that the hydroelectric power plant is one of the energy sources that can be developed. Jambi is an area covered with Batanghari River flows. This research aims to know how the work process of Microhydro power plant.  Components of the essential components of miniature microhydro power plants are reservoirs, rapid pipes, turbines, generators where these components are not loose bias, interrelated to one another. Round of Tubin obtained from the experiment is 400 rpm with water discharge 0.0016 m3/s. The maximum voltage generated by the generator is 18 volts. Voltage generated from the generator to charging the Batrai used inverter of 13.1 volts. The load will remain on even though the main energy source is the generator stop in the same, because the energy of the second is Batrai.

Abstract

Variable speed drives and the importance of controlling the speed of existing motors have attracted much attention with the advent of new electrical devices and magnetic materials. This paper is a comprehensive review of the application of VFD in energy saving electric motors. The aim is to identify energy saving opportunities and apply variable speed drives to existing electric motor applications. In this paper the authors hope to provide useful information for future variable speed drive applications such as fans, pumps, coolers, ventilators and as electric car propulsion. In this study, a series of frequency changes has been tested as an induction motor speed regulation (VFD), which in the results of this frequency change research can regulate the speed of the induction motor. In this study, the frequency change is still regulated analogously by changing the resistor size on the PWM signal generator IC for the MOSFET driver. For that the next research is expected to change the frequency can be done digitally

Abstract

Boost Converter adalah perangkat catu daya listrik untuk menaikan tegangan DC (Direct Current), teknologi Boost Converter ini berdasarkan pada mode pensaklaran menggunakan pembangkitan sinyal PWM (Pulse Width Modulation )yang diperuntukan  kepada komponen saklar daya  pada rangkaian Boost Converter, sinyal PWM ini mempunyai duty cycle untuk memberikan kendali pada kenaikan keluaran tegangan. Pada penelitian ini pengaturan duty cycle menggunakan LDR (Light Dependent Resistor), yang mana pada fungsinya LDR akan mempunyai nilai hambatan yang besar dalam keadaan gelap dan mempunyai nilai hambatan yang kecil dalam keadaan terang. Hasil pengujian yang dilakukan LDR mampu memberikan perubahan  duty cycle terhadap perubahan intensitas matahari sehingga perancangan Boost Converter pada penelitian ini mampu menaikan besar tegangan keluaran pada panel surya

Abstract

The adapter / power supply is a DC voltage source that is used to provide voltage or power to various electronic circuits that require DC voltage to operate. The main circuit of the power supply is  a rectifier, which is a circuit that converts an alternating signal (AC) into a direct signal (DC). The conversion process starts from rectification by the diode. In this paper, the Ripple Voltage Filter is carried out using a passive filter and the average voltage drop of the filter is 64%, the regulation (regulation) by the regulator circuit, the provision of this DC electrical energy source is to provide a unidirectional variable voltage ( DC) which aims to provide practical tools in Batanghari University electric laboratories while the benefits obtained from the research results are as a tool for practical activities in the electrical engineering laboratory of Batanghari University, Jambi.

Abstract

Sistem tenga listrik dapat dikatakan memiliki keandalan yang tinggi apabila sistem tersebut menyediakan pasoka energi listrik yang dibutuhkan konsumen secara kontinyu, pada kenyataannya permasalahan yang dihadapi penyaluran sistem tenaga listrik adalah gangguan kedip tegangan (voltage sags) yang diakibatkan gangguan hubung singkat pada sisi penyulang,  Penelitian ini menganalisa kedip tegangan yang terjadi pada Saluran Udara Tegangan Menengah (SUTM) 20 KV akibat gangguan hubung singkat tiga phasa berdasarkan jenis konduktor yang digunakan pada sisi penyulang, kajian dilakukan dengan asumsi sistem penyaluran tanpa gardu hubung dan menggunakan  konduktor  AAC dan AAAC. Hasil penelitian menunjukan besar magnitud arus ganggan hubung singkat tiga phasa pada kedua konduktor menyerupai disepanjang penyulang, sedangkan besar kedip tegangan yang terjadi disepanjang penyulang menyerupai jika terjadi gangguan dititik 0% - 10% panjang penyulang dan terdapat perbedaan besar kedip tegangan apabila gangguan terjadi diatas 25% panjang penyulang. Hasil dari penelitian ini dapat digunakan untuk keperluan penyetelan proteksi pada sisi penyulang dalam menjaga keamanan dari penyaluran energi listrik.

Abstract

This study aims to plan a solar power plant with an off grid system that will be used for electricity needs in Hamlet Kunangan Jaya 2 RT.28 which is one of the Hamllet in Bungku Village. Bungku Village is included in the 3T area, which is left behind, foremost, and outermost.Hamle Kunangan Jaya 2 RT.28have not enjoyed electricity from PLN due to difficult access and far from urban areas.The research was conducted with a descriptive research method. The selection of this type of method is used on the basis of the consideration that the nature of the research describes a plan carried out to meet the electricity needs of public facilities. Studies field were carried out to determine the electricity needs of public facilities: Mosques, Polides, and Elementary Schools, find out the number of panels needed, measure solar radiation and measure the area of the building. Calculation of electricity requirements is carried out in order to find out how much electricity is needed in public facilities, carry out design plans and calculate a budget plan to describe the planned installation. The results of solar data measurement for Optimal Global Irradiation in Bungku Village are 4,549kWh/m2 per day, the required amount of solar cell power is 6,000WP, three 40A Solar Charger Controllers, 2,800Ah batteries and 8000Watt Inverters. The total load required for mosques, polides, and elementary schools is 25,126Wh. The total RAB for PLTS development using an off-grid system requires a cost of IDR 138,647,000.
