This paper introduces a groundbreaking approach to revolutionize traditional farming practices by introducing a decision model-based agricultural electrical automation control system. The system integrates cutting-edge technologies, including artificial intelligence (AI), machine learning (ML), and sensor networks, with the goal of enhancing the efficiency and productivity of agricultural processes. By automating key tasks such as irrigation, fertilization, pest control, and harvesting, the s...

A Fault Detection and Protection Scheme for a 200 MVA Transformer using Fuzzy Logic

ABSTRACT Condition monitoring of Electrical power equipment has attracted considerable attention for years. The aim of this work is to use Fuzzy logic (FL) Tool Box in building a simulation system that will diagnose all kinds of incipient faults, phase to phase fault and overloading in a transformer and monitor its conditions. Current and rate of change of current with time have been identified as the input variables, duly represented in the programme as “Error” and “Error-Dot”. Thes...

Comparative Analysis of Distributed Power Control Algorithms in Cellular Network

ABSTRACT Wireless Communication is one of the most active areas of technological development of our time. It covers a very wide array of applications that lead to an ever growing demand on the limited radio resources. Consequently, the need for efficient management of the limited radio resources has become imperatively a global issue. The complexity of the cellular system and the propagation channel resulted in the interference issues that degrade the system performance. Transmit power otherw...

Multi‑time Scale Coordinated Optimization of New Energy High Permeability Power System Considering Flexibility Requirements

The high proportion of grid-connected intermittent energy such as wind power and photovoltaic makes the demand for power system flexibility increase sharply. In order to improve the overall flexibility of new energy high permeability system and enhance the economy of power system, promote the new energy consumption of system. This paper presents a multi- time scale Coordinated optimization strategy for the new energy high permeability power system considering flexibility requirement (MTS...

Robotic Soil Instrument

Soybeans are an important crop for global food security. Every year, soybean yields are reduced by numerous soybean diseases, particularly the soybean cyst nematode (SCN). It is difficult to visually identify the presence of SCN in the field, let alone its population densities or numbers, as there are no obvious aboveground disease symptoms. The only definitive way to assess SCN population densities is to directly extract the SCN cysts from soil and then extract the eggs from cysts and count ...

Wearable Devices and Connected Worker Solutions

The effects of the workplace on the safety, health, and productivity of personnel can be seen at various levels. To protect and boost general worker health, innovative hardware and software tools have been developed for the detection, elimination, substitution, and regulation of occupational hazards. Wearable technologies make it possible for constant tracking of workers and their environment, whereas connected worker solutions provide contextual information and support for decision-making. H...

A Pulse Width Modulated Voltage-Fed Inverter Vector-Controlled Permanent Magnet Synchronous Motor Drive

ABSTRACT  A Pulsewidth Modulated Voltage-Fed Inverter Vector-Controlled Permanent Magnet Synchronous Motor (PMSM) Drive based on Hysteresis Current Control (HCC) is presented in this work. A detailed conceptual dq modelling of the PMSM was undertaken in the rotor reference 26 frame for open loop studies, thereby setting the pace for the variable speed drive (VSD) of the PMSM which, inherently, is not capable of variable speed operation. Subsequently, vector control by Field Orientation Contr...

Design and build an electric car charger station with a renewable source of energy at IUK

Abstract Construction and use of electric cars have increased dramatically in recent years. It's totally silent, productive, wasteful to a minimum, and needs zero care. Although electric vehicles might help cut down on carbon dioxide emissions, the charging stations required to keep their batteries at an adequate level would put a significant strain on the country's electrical grid. Renewable energy sources, such as solar power, have the potential to lessen the burden on the power system. Ass...

Influence of Saliency Ratio (Xd, Xq) on the Performance of Three-Phase Synchronous Reluctance Generators.

ABSTRACT  In the study of the influence of saliency ratio (L /L ) on the performance of a synchronous reluctance generator (SRG), this project investigates two typical generator rotor designs: Generator with cage and without cage otherwise known as cage and cageless rotor respectively. A special attention had been paid to the possible rotor geometries of synchronous reluctance machine, SRM. This ratio can directly influence our insight into the machine’s potential abilities. From the studi...

Modeling and Simulation of a Standalone Photovoltaic System

ABSTRACT  The increase in hazardous gaseous emission from the conventional source of energy has motivated many scientists to research on the alternate sources of energy which is cleaner. The chief source of renewable energy is the solar energy. The cleanness of this form of energy source motivated this research work. In this work, Modeling and Simulation of a Standalone Photovoltaic System aimed at increasing the efficiency of solar array system was developed. This work was undertaken to dev...

An Improved Model for Key Performance Indicators Analysis for Mobile Number Portability Scheme for GSM Subscribers in Nigeria

ABSTRACT  In Nigeria today it been observed that when changing from one GSM network operators to the other, customers has to give up their old numbers and adopt a new one. As a result, they face switching costs associated with informing people about changing their number, printing new business cards, missing valuable calls from people that do not have the new number, etc. In this research the Key Performance Indicatiors (KPI) of network providers and the causes of poor quality service qualit...

Comparison between Proportional Integral Derivative Controller and Fuzzy Logic Controller for DC Servomotor

ABSTRACT This study presents a comparative study of two controllers for position and speed control of DC servomotor. PID controller is the most usually used for the position control in DC servomotor. However, the PID controller has some disadvantages such as: the high starting overshoot, slow response for unexpected disturbance and high sensitivity to the controller gain. So, the reasonably design PID controller with computational optimization approach method is proposed to overcome the disad...

Thermal Modelling of Induction Machine Using the Lumped Parameter Model

Abstract Temperature rise is of much concern in the short and long term operations of induction machine, the most useful industrial work icon. This work examines induction machines mean temperatures at the different core parts of the machine. The system’s thermal network is developed, the algebraic and differential equations for the proposed models are solved so as to ascertain the thermal performances of the machine under steady and transient conditions. The lumped parameter thermal method...

Policy and Regulatory Framework for Fiber Optic Backbone in Abuja

ABSTRACT The purpose of this work is to make a contribution to the “Abuja grand design” by proposing a strategy that would facilitate making Abuja feature as a “modern city”. This proposal is entitled “Policy and Regulatory Framework for Fiber Optic Backbone in Abuja”. The main import of the strategy is to network every home and business in Abuja with fiber optics. The city fiber network would serve as a broadband communication medium to provide essentially unlimited and open comm...
