    PERFORMANCE COMPARISON OF TWO PLANAR MONOPOLE ANTENNA FOR ULTRA-WIDEBAND APPLICATIONS
    (Department of Electrical Engineering, Ahmadu Bello University, Zaria, 2020-03) Jabire, Adamu Halilu; Saminu, Sani; Goje, Ahmad Daiyibu; Ochonu, Agidike Lawrence; Wesley, Dansarki Nanly
    In this communication, two distinct compact planar monopoles are designed and constructed. Two composition (circular and rectangular shaped radiating elements) are presented. The slots and step-shaped are integrated in the radiating elements to improve the impedance matching characteristics of the antennas. Two feeding techniques (microstrip and coplanar waveguide feeds) are performed to couple the electromagnetic waves. Both the two antennas shows promising performance for UWB applications. Numerical and exploratory strategies are performed to exhibit and discuss about the proposed designs. The results of CPW-fed receiving wire uncover preferable execution over the transmission line fed reception apparatus

    A Review on Optimal Siting and Sizing of D-STATCOM
    (Faculty of Engineering Universitas Riau, Pekanbaru, Indonesia, 2022-02) Wesley, Dansarki Nanly; Abdulkarim, Abubakar; Okorie, Patrick Ubeh; Jabire, Adamu Halilu; Saminu, Sani; Faruk, Nasir; Oloyode, Abdulkarim; Madugu, Ibrahim Sani; Lawan, A. U.; Rosma, Iswadi Hasyim
    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.
