Design and Construction of a Four Way Traffic Light Control

ABSTRACTA traffic light also known as a traffic signal,  stop light and go light, robot or semaphore is a signally device positioned at four (cross) junction, pedestrian crossing or other locations in other to indicate when it is safe to drive or walk using a universal color code ( and in precise sequence for those that are color blind).Traffic light system operate on a turning mechanism that changes the light after a given interval of 7-120 seconds depending on the traffic congestion on...

Contactless Power Transfer System Using Inductive Coupling-based Wireless power transfer (WPT) Principle

Wireless power transfer (WPT) technologies have been widely used in many areas, e.g., the charging of electric toothbrush, mobile phones, and electric vehicles. This project introduces fundamental principles of three WPT technologies, i.e., inductive coupling-based WPT, magnetic resonant coupling-based WPT, and electromagnetic radiation-based WPT, together with discussions of their strengths and weaknesses. Several WPT applications are described. Open research challenges are then presented wi...

The Role of Satellite Network in future 5G wireless networks

ABSTRACTThe document outlines an investigation done in order to study Fifth Generation (5G) systems and to identify a role that satellite systems will play in contribution to the many advanced and diverse demands on existing telecommunication networks. This next generation network is a build-up and phenomenal improvement in wireless communication done by the “5GPP” on the already existing mobile generations. The evolution has seen us move from first generation which employed...

Commutation failures in HVDC Schemes

Commutation failures are very frequent dynamic events in high voltage dc (HVDC) transmission systems. Commutation failure is mostly observed at the inverter side of HVDC links, where large firing angles are used. The minimum value of the extinction angle required for the proper operation of a valve is specified by the valve manufacturer; however, at the inverter side of HVDC systems the extinction angle is regulated to a value higher than the valve specifications to allow control adjust...

The ability of AC/DC converters to generate and consume reactive power

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 provi...

Voltage Collapse in Power System

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 subje...

Variable Speed Drives for AC machines

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 mos...

Optimal Placement of Capacitors in a Distribution System

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 ch...

DESIGN CONSTRUCTION AND IMPLEMENTATION OF A TOUCH SENSITIVE SWITCH

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...

ANALYSIS OF OPTIMUM ECONOMIC LOADING IN AN ELECTRICAL POWER SYSTEM

ABSTRACTElectricity 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 ...

Construction of a Digital Display Board

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 enhance...

DESIGN AND IMPLEMENTATION OF AUTOMATIC SECURITY LIGHTING SYSTEM FOR ATBU YELWA CAMPUS.

ABSTRACTThis project work has covered the design of an automatic security lighting system for ATBU, Yelwa Campus. Requirements for illuminance, type of fittings, power dissipation and mounting height were put into consideration. An electronic model of the campus was built with the streets outlined and lamps fixed at positions along the streets according to the design. An electronic control, based on a Light Dependent Resistor (LDR) is built, which provides automatic switch on and switch off o...

DESIGN AND CONSTRUCTION OF 100W ELECTRIC POWER INVERTER

ABSTRACTNo one form of power can sustain a nation. The ever increasing demand for electrical power has arisen from our lifestyles with revolves around electric power to speed up processes of development such as manufacturing, service provision and general well being of man.The need for the provision of quick but minute energy to prevent the disruption of small but very important business or personal processes could be life saving promoting efficiency at all times.This project work goes throug...

INTEGRATION OF DISTRIBUTED GENERATION (DG) OF ELECTRIC POWER SUPPLY

Adding to the requirement and need for power supply for day to day activities, it is therefore a necessity to design the power system to maintain minimal technical losses in the network, because most of our system component lack sufficient reactive power ability, this mean that the penetration of distributed generation (DG) will give way to reduce the transmission and distribution system resources thereby increase the reliability and probably better the power quality at all time. Hence the ob...
