ALTERNATIVE CURRENT PULSE WIDTH MODULATION CONTROL FOR INDUCTION MOTOR

ABSTRACTAn induction or asynchronous motor is a type of AC motor where power is supplied to the rotor by means of electromagnetic induction, rather than by slip rings and commutators as in slip-ring AC motors. Single phase induction motor is the most familiar of all electric motors & they are similar to a 3-phase squirrel cage induction motor. It has a squirrel-cage rotor identical to a 3-phase motor and a single phase winding on the stator. There are several methods for controlling the speed...

INDUCTION MOTOR CONTROL SYSTEM

ABSTRACT The present invention relates to an improved control system for starting a three phase induction motor comprises improved power contactors configured to have a pair of three pole delta and main contactors, and a single pole star contactor for supplying AC power to star position and delta position, a timer for controlling AC power supply switching operation for star position and delta position and for adjusting a time delay of switching over from star connection to delta ...

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 ...
