Abstract

Distribution Network is one of the parts in a power system that has an important role because it deals directly with users, especially the users of medium and low voltage level. Therefore it needs a protection system against abnormal condition to maintain the reliability of the system. The protective equipment analyzed in this article is the overcurrent relay (OCR) and ground fault relay (GFR). The aim of the article is to determine the settings of OCR and GFR protection devices. By calculating the short circuit, the current and time settings of OCR and GFR can be determined. The short circuit current was simulated by using DigSILENT PowerFactory. It has been found from the results that time setting is influenced by value of short circuit current. The higher the fault current the the faster the trip time of the protection devices. Keywords: Short Circuit, Protection, Relay Setting, DigSILENT

Abstract

Solar energy in the form of light emitted (radiation) to the earth can be used as the main source to produce electrical energy directly by using the solar photovoltaic function (SPV) or also called the photovoltaic effect. The electrical energy generated from this SPV is in the form of a DC voltage. The energy produced by SPV needs to be researched to understand the characteristics of SPV in different places and conditions. The research conducted was to observe the SPV characteristics for weather conditions in Pekanbaru. Sunlight that radiates on the SPV was placed at an angle of zero degrees horizontally with the surface of the earth. The method that used to obtain SPV characteristics is stand alone solar photovoltaic testing by installing a rheostat (variable resistor) at the SPV output. it's value is 0-100 Ohms which will then be shifted from the largest value to the smallest rheostat value. From the tests conducted will produce SPV characteristic parameter data and can form curves I - V and P – V. The results of real-time measurements produce data to form a characteristic curve, ISC of polycrystalline solar photovoltaic type was 1.0232 V while monocrystalline solar photovoltaic ISC was 0.92912 V. The open circuit voltage (VOC) in both types of solar photovoltaics had the same value which was 20.41 Volts. Keywords: solar energy, solar photovoltaik, rheostat, curves, stand alone

Abstract

The continuous demand for electrical energy by industries and domestic users have stressed the electricity consumption to a high level. Because most components of domestic and industrial systems are made of power electronics devices in their designs. In addition, modern electrical power distribution networks (DNs) are subjected to major disturbances. Consequently, today’s power system is laden with power quality problems such as excessive energy losses, voltage deviations, poor power factor (PF), voltage instability and reliability issues to mentioned just a few. To forestall these disturbances, Distribution Engineers have introduced the use of Custom Power Devices (CPDs) in order to reduce power losses so as improve power quality. Amongst CPDs, Distribution Static Compensator (D-STATCOM) proves most promising in minimizing power quality issues because it generates minimal harmonics, waste less power, has small size, high regulatory capability and cost effective. Researchers in recent years have focused on methodologies required for identifying the most suitable location and rating of D- STATCOM device based on divergent views. However, to date, only one author has so far reviewed a paper on this aspect of study. This paper discusses the latest study on appropriate installation and rating of D-STATCOM techniques for balanced and unbalanced radial distribution networks (UBRDNs). The paper has also provided a comprehensive literature study on the location of DSTATCOM in RDNs for power loss reduction and power quality enhancement. Comparative analyses of various techniques for development of DSTATCOM Objective functions and constraints; Merits and Demerits are presented.

Abstract

An aerator is a device that utilized to produce dissolved oxygen in water through a diffusion process. Generally, the aerators employed by farmers are operated manually by an operator. The design and utilization of a smart device such as the Zelio Smart Relay is one of the objectives of this article. With the use of smart relays, it is expected that the presence of operator can be eliminated and able to reduce operational cost. The type of aerator discussed in this article is a dual turbine aerator. Each turbine has 6 blades. In order to have the smart relay to operate properly, at least 2 (two) sensors are needed as inputs, namely the light intensity and the temperature sensor. Furthermore, dissolved oxygen levels in water are categorized as high (30 mg / L) if the light intensity is higher than 100,000 lux and the temperature lower than 350 C. It shows in the results that the implementation of aerator has the capabilty to increase dissolved oxygen from 8 mg / L - 14.4 mg / L in 45 minutes, therefore the quantity and the quality of dissolved oxygen required by shrimp farming can be fulfilled properly.BAHASA INDONESIA ABSTRACT: Aerator adalah salah satu alat bantu yang berfungsi untuk memproduksi oksigen terlarut dalam air melalui proses difusi. Sampai saat ini, aerator yang dimanfaatkan oleh para petani pada umumnya masih bersifat manual dengan cara dioperasikan dan dikendalikan oleh tanaga operator (manusia). Perancangan dan pemanfaatan teknologi cerdas seperti Zelio Smart Relay merupakan salah satu bahasan pada artikel ini. Dengan adanya pemanfaatan smart relay tersebut diharapkan pekerjaan operator pada pertanian tambak udang dapat dipermudah dan mampu menekan biaya operasional. Jenis aerator yang dibahas pada artikel ini adalah aerator turbine ganda yang memiliki 6 buah sudu di tiap tiap kincirnya. Agar sistem kendali yang dirancang pada smart relay beroperasi dengan baik, maka diperlukan sedikitnya 2 (dua) buah sensor yaitu sensor intensitas cahaya dan sensor suhu yang terukur pada kolam (air). Selanjutnya kadar oksigen terlarut dalam air dikategorikan tinggi (30 mg/L) apabila intensitas cahaya > 100.000 lux dan untuk suhu < 350 C. Dari hasil penerapan aerator di kolam dapat diketahui bahwa aerator dengan penambahan Zelio Smart Relay ini dapat bekerja sesuai dengan perancangan, yaitu dapat meningkatkan oksigen terlarut dari 8 mg/L – 14.4 mg/L dalam 45 menit, dengan demikian kuantitas oksigen terlarut yang dibutuhkan oleh pertanian udang dapat dipenuhi dengan baik.

Abstract

Ketersediaan air yang cukup dan terus menerus merupakan salah satu faktor penting yang mempengaruhi keberhasilan usaha di bidang pertanian dan perikanan. Selama ini usaha pertanian dan perikanan masih bergantung terhadap air hujang yang terjadi pada musin tertentu. Karena musim hujan tidak terjadi sepanjang tahun, maka usaha pertanian dan perikan di lokasi studi kasus (Desa Batu Bersurat Kabupaten Kampar) tidak dapat berlangsung secara berkesinambungan dalam satu tahun penuh. Oleh karena itu, tujuan utama artikel ini adalah membahas tentang penerapan pompa hydraulic ram pump (hydram) untuk memenuhi kebutuhan air di lokasi studi kasus mitra pertanian dan mitra perikanan tersebut. Pemilihan pompa hydram untuk menjamin ketersediaan air adalah bahwa teknik ini tidak membutuhkan sumber tenaga listrik sehingga dalam pengoperasiannya akan memberikan penghematan biaya operasional dan ramah terhadap lingkungan. Selain itu, artikel ini juga menganalisis tahapan demi tahapan pembangunan poma hydram hingga dapat beroperasi sesuai dengan rancangan yang telah dibuat. Dari hasil pengukuran yang diperoleh didapatkan kinerja pompa hydram adalah 0,5 L/menit sehingga untuk mengisi 2 buah tanki air dengan kapasitas total 2.100 L dibutuhkan waktu pengisian selama 35 jam.
