Abstract

Wireless power transmission technology can eliminate the use of cables, thereby increasing the mobility, convenience and security of electronic devices for all users. The wireless photovoltaic power transfer system will be modeled using Mathlab Simulink software built by a PV module, half-bridge inverter, transmitter and receiver coils. The distance between the transmitter and receiver coils is changed from 1 m to 10 m. PVWPT (Photovoltaic Wireless Power Transfer) is a system that combines photovoltaic (PV) technology and wireless power transfer to transfer electrical energy from a PV module to a receiving device or system without using physical cables. By using PVWPT, electrical energy can be generated from sunlight by PV modules and wirelessly transferred to receiving devices that require power. The farther the distance, the less voltage will be sent. And the error percentage is 5%.

Abstract

Transfer daya nirkabel (WPT) adalah sebuah konsep untuk mentransfer daya listrik dari kumparan pengirim ke kumparan penerima tanpa kawat. Para peneliti sebelumnya telah mempelajari tentang WPT menggunakan implementasinya dalam pemodelan simulasi, tetapi itu sedikit pendukung yang berhubungan dengan matematika perumusan, terutama dalam jarak antara pengiriman dan kumparan penerima. Makalah ini menyajikan pemodelan simulasi Sistem WPT menggunakan MATLAB SIMULINK berdasarkan formulasi matematis yang berkaitan dengan induktansi induktor dari koil pengirim dan penerima, putar nomor koil dan induktansi timbal balik sebagai wakil dari jarak antara kumparan pengirim dan penerima. Hasil simulasi menunjukkan bahwa gelombang pulsa 5 kHz dihasilkan oleh generator pulsa menggerakkan terminal gerbang MOSFET yang mengubah DC menjadi tegangan AC 5 kHz pada koil pengirim menjadi setengahnya rangkaian inverter jembatan. Koil pengirim menghasilkan AC rms-nya tegangan 837,92 V untuk jarak 10 m dan juga AC tegangan diinduksikan pada kumparan penerima dengan tegangan rms nya, arus dan daya adalah 8,22 V, 14,17 A.

Abstract

Wireless power transfer (WPT) is a concept for transferring electrical power from a sending coil to a receiving coil without a wire. Researchers have previously studied WPT using its implementation in simulation modeling, but it supports little in terms of the mathematics of the formulation, especially in terms of the distance between the sending and receiving coils. This paper presents simulation modeling of the WPT System using MATLAB SIMULINK based on mathematical formulations relating to the inductance of the sending and receiving coils, coil turn number and mutual inductance as a representative of the distance between the sending and receiving coils. The simulation results show that the 5 kHz pulse wave generated by the pulse generator drives the MOSFET gate terminal which converts DC to 5 kHz AC voltage at the sending coil to half the bridge inverter circuit. The sending coil produces an AC rms voltage of 837.92 V for a distance of 10 cm and also an AC voltage is induced in the receiving coil with its rms voltage, current and power are 8.22 V, 14.17 A.

Abstract

Background: Thalassemia is an inherited autosomal recessive disease resulting from mutations in the α- and β-globin gene clusters on chromosome 16 and chromosome 11, respectively. The aim of this study to show about prevalence, management and outcome of thalassemia in children. Methods: By the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, this study was able to show that it met all of the requirements. Result: Eight publications were found to be directly related to our ongoing systematic examination after a rigorous three-level screening approach. Subsequently, a comprehensive analysis of the complete text was conducted, and additional scrutiny was given to these articles. Conclusion: The prevalence and gene mutation spectrum of thalassemia display obviously heterogeneity among children. The findings provide the valuable information for premarital and pre-pregnancy screening, prenatal diagnostic services, and designing appropriate prevention programs to control thalassemia for future.

Abstract

The grounding system in substations generally uses electrode rods, because electrodes can affect the effectiveness of fault current conduction, so the equipment will be safer. Considering the importance of the grounding system, the installed grounding system must be considered and maintained properly. One of them is the grounding found in Glugur. The main objective of this research is to comprehensively evaluate the substation grounding system by modeling the grounding system at the Glugur Substation using MATLAB graphical user interface (GUI). The grounding resistance follows a grid system with an area of 20×15=300 m² with specific resistance being clay using 100 rod electrodes. From the results of ground resistance simulation modeling using MATLAB GUI, it can be concluded as follows: for a certain resistance value, the number of electrodes for 100 Ωm is 3.55 Ω, for ground resistance with a constant depth and a varying number of 100 electrodes, it is 3.45 Ω, and for. The grounding resistance with a constant and varying number of 1,000 rods is obtained at 2.65 Ω. From these results, the modeling carried out is in accordance with the standards of electricity regulations in Indonesia.

Abstract

The use of renewable energy is increasingly important to meet energy needs and reduce the negative impacts of fossil fuel use. Universiti Malaysia Perlis (UniMAP) plays an active role in the socialization of renewable energy through educational programs and grants of related books aimed at increasing public understanding of the benefits of sustainable energy. Collaboration with Universitas Medan Area and Al-Azhar University will expand the reach of this socialization and enable the exchange of knowledge and experiences in the field of renewable energy. These books cover a variety of topics on renewable energy and green technology, and will be distributed in seminars and workshops involving academics and local communities from the three institutions. With this effort, it is hoped that awareness of the importance of the transition to clean energy will increase, encourage sustainable practices, and strengthen research in the field of renewable energy at UniMAP and partner institutions, making it a model for other institutions in promoting sustainable practices in the community.

Abstract

A photovoltaic direct current (DC) power can be changed into AC power using an inverter. The inverter must be connected to an alternating current (AC) load using wire, which has drawbacks in terms of air space, wire cost, and an unattractive view of the sky. It is appropriate to suggest a wireless power transfer (WPT) system concept to replace the use of wires in the transfer of electrical power. The WPT system has been conducted by the previous researchers, but it is still in the frequency system of hundred, kilo, mega or gigahertz, thus it can only be applied on DC load after rectifying it, but cannot be applied for a normal AC load, also its distance is relative near. The modelling of wireless photovoltaic power transfer (WPVPT) with a 50 Hz system frequency is presented in this work. The four modelling components that create the WPVPT system are models of the PV module, the transmitter circuit, the magnetic relay, and the receiver circuit. The findings indicate that the efficiency of the proposed WPVPT system is 71.27% without a magnetic relay and 72.82% with a magnetic relay. It suggests that the use of magnetic relay can improve the WPVPT system's efficiency.
