ABSTRACT Oil Industry has become the most important part of Sudan Economy and is playing the main role for country incomes. White Nile Petroleum Operating Company (WNPOC) is one of the Oil Operating Companies which has been producing crude oil since 2006; one of its running fields is Mala fields which comprise the following sub fields: • Mala Main, • Mala North, • Mala East and • Mala South East. When these fields were commissioned and started-up, there appeared continuous power out...
ABSTRACT The purpose of this project is to design and implement a digital wattmeter that can measure wattage of a circuit The design is implemented using the microcontroller ATMEGA 8, based on the principle of calculating power mathematically two ATMEGA8 were used, one for measuring current while the other for measuring voltage, the multiplication of the voltage and current values gives the wattage reading. At the end of the process the LCD displays the voltage, current and wattage readin...
ABSTRACT This project presents a single phase inverter system which serves as an alternative power supply. The conversion technique used is first converting the low voltage DC power to AC power using pulse width modulation (PWM), then boosted to high AC voltage using a step up transformer for constant output voltage instead of boosting the low voltage DC power to high voltage power source using a DC- DC booster which is then convetted to AC power using pulse width modulation (PWM). It is ...
ABSTRACT An integration of Vehicular Ad-hoc Network (VANET) and cellular network, e.g. LTE is a promising architecture for future machine-to-machine applications. This integration helps vehicles to have steady internet connection through cellular network and at same time can communicate with each other. However, dead spot areas and unsuccessful handover processes, due to vehicles high speed, can disturb the implementation of this kind of architecture. In this thesis, a Simplified Cluster –...
ABSTRACT This project is about the Design and Construction of a Vehicle Tracking and Accident Alert System (VTAA) using GPS and GSM Technology. It comprises of integration between GPS receiver, microcontroller and GSM module, and of course the push button for accident alert activation. The combination of all this technology wilJ produce our VTAA system. The GPS module receive the coordinate of the point at which the system is located, controlled by the user using command interfaces thro...
Abstract In the present study, a new technology controlled Ethanol/Water mix injection method is applied to a direct injection (DI) diesel engine to show effect on engine performance and emissions under steady operation. Ethanol/water mix is injected into the inlet manifold during inlet period. The experimental test matrix included six different fuels, namely Neat Diesel fuel and five secondary Ethanol/Water mix fuel with diesel fuel. The mixed fuels contain 0.55–2.79 by volume fraction of...
Abstract One motivation of grid computing is to aggregate the power of widely distributed resources and provide non trivial services to users. To achieve this goal an efficient grid scheduling system is an essential part of the grid. The scheduling of the processes can be implemented in different ways with different scheduling algorithms. In this project we use Shortest Job First [SJF] algorithm where it assigns highest priority to shortest process. If processes are long, it suffers with a l...
ABSTRACT The design of the wireless audio and video transmitter was done in stages taking into consideration a pre-selected desired frequency. These stages are the power supply stage, the carrier frequency generation stage, the carrier frequency pre-amplification stage, the voltage controlled oscillation stage and the final stage which is the modulation and amplification stage. First, carrier frequency was generated in the oscillator circuit comprising of an NPN transistor Cl 674, a vari...
Abstract Conventional methods of system load shedding are too slow and do not effectively calculate the correct amount of load to be shed. This results in either excessive or insufficient load reduction. In recent years, load shedding systems have been repackaged using conventional underfrequency relay and/or breaker interlocks schemes integrated with Programmable Logic Controllers to give a new look to an antiquated load preservation methodology. A truly modern and intelligent load shedding...
ABSTRACT This study was carried out on River Atuwara in Ota, Ogun State, Nigeria with the aim of developing a coefficient of re-aeration model applicable to River Atuwara and other rivers in the Nigerian environment. This was achieved by sourcing for data once every month from 22 sampling locations of interest within a pre-selected segment of the river over a period covering the dry and wet seasons. The data collected include hydraulic data (depth, width, velocity and time of travel) and wat...
Abstract Control system is integral part of modern society numerous applications are all around the whorled. The rockets live and the space shuttle lifts of the orbit in splashing cooling water, a malleable part is automatically machined a self guided vehicle delivering mechanical to work station in an a era space assembly planet glides along the floor speaking it’s destination. In modern industries the maintaining and handling of disturbance has a grate significance of efficiency and cost...
ABSTRACT In the last two decades, electricity generating plants in Nigeria have been operating below their capacity with available capacity barely surpassing half the installed capacity which is short of international standards of over 95% installed capacity. Due to this low availability, other key performance indicators such as capacity factor and load factor have also been relatively low. This research work therefore aims at evaluating the performance of selected gas turbine power plants i...
ABSTRACT Power quality is a global issue due to electronic equipment becoming the backbone of the modernday economy; it affects consumers, distribution, and transmission networks. This research work focuses on evaluating and proposing improvement of the measured power quality on the distribution network in Covenant University. Electrical equipment used in Covenant University can lead to power quality problems, measurements and evaluations are to be done from time to time to monitor the distr...
ABSTRACT The emission of noxious elements from building ceiling fire is increasingly becoming a source of concern globally. Hence, there is the need to develop eco-friendly flame-retardant building ceilings from composite materials to forestall the unwanted toxic emissions. This study aims at developing a bio-degradable hybrid aluminium dross ceiling utilizing varying material percentages using the moulding process. Box-Behnken factorial design from Minitab 17 was used to analyze the effect ...
ABSTRACT Power system voltage instability often results in voltage collapse and/or system blackout which is a source of concern for power network operators and consumers. This work proposes a new line stability index that is suitable for investigating the voltage stability condition of Power System Networks (PSNs). This index, which is called the New Line Stability Index-1 (NLSI_1), is derived from first principles and shown to incorporate the Line Stability Index (Lmn) and the Fast Voltage ...
