Design of a 1 kva PV system for electrical laboratory in faculty of engineering, University of Uyo, Nigeria

Abstract

One of the most challenging issues in most developing countries of the world today remains access to electricity. In areas where there is access to electricity, the epileptic nature of the supply and the inconsistency of the generated voltage and over loading pose a serious threat to the safety of electricity consumers equipment. In Nigeria, just like most developing countries, the situation is not different, hence the need for this study. In this work, a 1 KVA Photovoltaic (PV) system was designed and implemented for use in the electrical engineering laboratory of University of Uyo, Nigeria. A 12 V 100 Ah storage system was integrated into the design to support laboratory emergency load of up to 6.5 hours off peak and 1.5 hours peak loads. The designed PV system was used during laboratory sessions and was seen to be effective and provided the needed solution to sudden power failure which is a predominant occurrence experienced during laboratory sessions.

Design and Dynamic Modelling of a Hybrid Power System for a House in Nigeria

“…Individuals and researchers across Nigeria have over the years taken advantage of the availability of abundant solar resources and its ease of use to design photovoltaic (PV) systems to meet their private energy needs. Udoakah et al [5] designed a 1 kVA PV system for electrical laboratory in the Faculty of Engineering at the University of Uyo to solve the problem of sudden power failures during laboratory sessions. The major components of their off-grid PV system design include two 150 W solar panels connected in parallel (PV module), an inverter unit, one 12 V, 100 AH deep cycle battery, charge controller unit, and an automatic control unit to automatically switch from the inverter to the public power supply whenever the public power was available and vice versa.…”

Performance Evaluation of a Micro Off-Grid Solar Energy Generator for Islandic Agricultural Farm Operations Using HOMER

“…In most cases, building a small PV system to meet the pumping requirements of the land is the sensible solution [12]. Effective sizing of the components is also important to ensure a reliable, adequate, and economical design [13][14][15][16][17].…”

Investigate the optimal power system by using hybrid optimization of multiple energy resources software

“…For example, the study of [21] analyzes the discrete micro-grid installed on the island of Kythnos, Greece, and in particular the technical and economic aspects of the replacement of diesel generators by fuel cells, electrolyte and traditional hydrogen storage. Udoakah et al [22] also analyzes two implemented micro-grids, independent and interconnected, both located by the sea side Athens, Greece [23]. Most of the articles above estimate the energy needs of hybrid/photovoltaic system by calculating the electrical power quantities needs for each household appliance by numerical calculating the optimum output power of the system [24].…”
