ABSTRACT The conversion of an input AC power at a given frequency and voltage to an output power at different frequency and voltage can be obtained with static circuits called power converters, containing controllable power electronic devices. Various power converters have been developed to fulfill the requirements of the wind power generation. The most common option for the generators used in wind power generation is “asynchronous”, because support for speed variations is provided. This ...
The power system is a highly nonlinear system that operates in a constantly changing environment; loads, generator outputs, voltage controllers, transmission lines, topology, and key operating parameters change continually. The behavior and output of the generators can be affected in a transient conditions. This transient condition can change the excitation and dynamics of the rotor which in turn produces undesirable oscillations of the system frequency and voltage magnitude. When subjected t...
ABSTRACT Industrial drive applications are generally classified into constant-speed and variable-speed drives. Traditionally, AC machines have been used in constant-speed applications and DC machines were preferred for variable-speed. Induction machine with drive systems are widely used in applications such as pumps, paper and textile mills, elevators, electric vehicle, subway transportation, home appliance and wind generation. The three-phase squirrel cage induction motor is the mostly used ...
ABSTRACT This project centers on addressing the issue of the lack of research and development in Nigeria, in this case, looking into the firefighting and emergency sector. In this industry, the safety of the firefighters is of paramount importance as it is only then that they can fully carry out their duties and tasks. Of all the products that make up a complete assemble of the firefighters’ PPE, it is their personal protective tunic that was used for this project as it is the basic and mo...
This project is about the incorporation of RFID and fingerprint system's for security for a library information system. Scope Of The Study Here the fingerprint identification technique will be used for maintaining the attendance record. The record of the fingerprints of various students was maintained in a database. i. For implementing java programming language will be used. ii. The database will be maintained over MySQL. Students are supposed to enroll their fingerprint at the beginning o...
GENERATION OF ELECTRICITY USING A DOUBLE CHAMBER MICROBIAL FUEL CELL ABSTRACT The microbial fuel cells (MFCs) was used to generate electricity from waste water and fresh water, Design MFCs using different types of materials for the electrodes on the generation of electrical power from two MFCs, operated identically with a waste activated sludge feed and understand how bacteria and other living or...
Abstract Optimal capacitor placement is concerned with the optimal location of capacitors in a distribution system such that energy losses are reduced to a minimal value and the voltage profile and power factor of the system is improved. The reactive power can be controlled in order to improve the voltage profile and minimize the system loss. Generally, some load bus voltage might violate their upper or lower limits during system operation due to disturbances and/or system configuration ...
ABSTRACT A switch is an imperative constituent of any electronic or electrical circuit. It can either be mechanical, electro-mechanical or electronic. Mechanical and electro mechanical switches are prone to wear and tear with time. The introduction of semiconductors has led to the invention of electronic switches that are more efficient, fast and durable. Further development of electronic switches led to the production of touch-sensitive switches. This project is based on the design and const...
ABSTRACT Electricity companies typically possess numerous units and they need to commit unit because electricity cannot be stored in a large-scale system and demand is a random variable process fluctuating with the time of the day and the day of the week. A problem that must be frequently resolved by electricity utility is to economically determine a schedule of what units will be used to meet the forecasted demand, and satisfy operating constraints. Lagrangian multiplier method is one of the...
ABSTRACT Electronic Digital message display Board is an electronic gadget that is capable of displaying length of alphanumeric characters, symbols and any form of representation on a matrix of light emitting diodes (LED) scrolling the characters across the screen for information disemination. This project set out to solve the problem of inadequate clarity, objectiveness and degree of comprehension inherent in paper bill boards. Also, response to the information is further enhanced when th...
ABSTRACT This project “maintenance of urban infrastructures (a case study of Ilorin metropolis)” lays emphasis on the various Infrastructures such as Roads, Rail, Electricity, Water-Supply, Solid Waste Management Facilities, Drainage Facilities and Sewerage. The various magnitude and the facilities provided were looked upon; the various defects and possible remedies to some specific infrastructures were also looked at. The major data collection procedures were from the various infrastruct...
ABSTRACT This research work show cases the potentials of Itakpe Iron concentrate for Magneto-rhelogical abilities. The concentrate was first ball milled to size reduce it then subjected to low magnetic strength from magnetic bits in-situ the magnetic fluid. It was determined that temperature affected the fluid inversely, as temperature increased at the shear rates from the viscometer and Newtonian viscosity calculated reduced, giving a negative relationship between temperature and Newtonian v...
ABSTRACT Urban population is rapidly increasing in Ilorin along with attendant increased water demand. The inadequacies of water supply services has forced the populace to depend on dug wells, boreholes, water tankers, street vendors etc. for their water needs. People spend hour’s daily carrying jerry can all around to collect and queue for water at the public water tap with high opportunity cost of time and intense economic wastage. This study assess the sustainability�...
A technical report on student work experience scheme on laptop repair. The students industrial work experience scheme (SIWES) established in 1973 by decree 23 of Federal Republic of Nigeria is the accepted skills training programme involving the students,universities and the industry (employers of labor), that is a part of the approved minimum academic standards in various degree programme for all the Nigerian Universities. I worked in the Engineering and Standards Department of the D...
ABSTRACT During this research work, namely; the undrained shear behavior of soils within Nnamdi Azikiwe University, five different samples within the university compound were analyzed. Some laboratory test was carried out for classification and identification of their engineering properties, these tests include particle size distribution, Atterberg limit test, specific gravity, and free swell tests. Also, shear strength test (UU triaxial test) at different cell pressures and one-dimensional c...
