ANALISIS KALIBRASI SENSOR BH1750 UNTUK MENGUKUR RADIASI MATAHARI DI PEKANBARU

Solar irradiance is one of significant parameter to describe to available potential of solar energy in a particular location. Measuring solar irradiance can be implemented by using different types of sensors, namely: pyranometer, pyrheliometer, light dependent resistor, photodioda and phototransistor. However, when implementing these sensors for solar energy potential measurement, a number of factors must be considered such as: sensor’s price and measurement capability. Therefore, the aim of this article is to analyze the used of low price solar irradiance sensor as part of automatic solar station for measuring solar energy potential in a particular site. BH1750 was used in this article where it has been found that it has limitations such as maximum capability is up to 55.000 lux. A method was introduced to increase measurement capability by putting a cover on the sensor. With this additional cover, specific calibrations need to be carried out to overcome sensor’s accuracy

PENERAPAN HYDRAULIC RAM PUMP (HYDRAM) UNTUK PERTANIAN DAN PERIKANAN DI BATU BERSURAT

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

Speed Control of Three Phase Induction Motor using Space Vector Width Modulation (SVPWM) Technique with PI Controller

This article aimed to design and simulated the speed control of a three-phase induction motor using a PI controller with Space Vector Pulse width modulation technique. The induction motor  used in this article is was designed at the Electrical Energy Conversion Laboratory, Riau University, with a power of 1.1 kW, 380 V, 2-pole. Meanwhile, the PI controller constants used in designing this induction motor were determined using the Fine Tunning method to obtain KP and KI values of 3.539 and 9.526, respectively. The tests were carried out by running simulations in three conditions, namely no load, full load, and variable load at a speed of 2800 rpm. The test results showed that the use of a PI controller can improve the speed response of induction motors by eliminating the steady state error. This is in addition to increasing the rise time response of the motor speed by 0.012s and 0.046s at no load and full load, respectively, when the rise time analysis is at the same value. It can also accelerate the motor to reach a peak speed of 0.247 s and 0.166s at no load and full load. In addition, SPVWM with PI controller can maintain speed setting even though there is a load change during operation, which can be verified with load testing

A Review on Optimal Siting and Sizing of DSTATCOM

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
