DEVELOPMENT OF A FUZZY LOGIC TECHNIQUE FOR BIOGAS GENERATION OF ELECTRICAL ENERGY
AbstractProduction of biogas energy is one of the important technical solutions that contribute to the transformation of energy system from being fossil fuel dependent to renewable energy originated. Thus, comprehensive understanding of biogas energy is necessary in order to develop an accurate and robust model that will predict and control the biogas production. This research paper develops a fuzzy logic controller model for biogas generation of electrical energy. A fuzzy logic alg...

HOW TO BUILD A DRONE FROM SCRATCH
Unmanned aerial vehicles have been around for decades, but they have achieved the greatest popularity in recent years with small commercial drones. The new so-called FPV (first person view) technology gave us a unique experience of flying and the advancement of GPS systems in drones opened a whole new world for passionate individuals. Of course, drones are not the only RC flying devices on the market, but their agile multi-rotors and their capability to take amazing photos and re...
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 ...
Future SCADA System for Smart Grid
ABSTRACTTraditional power grids are now transformed into Smart Grids (SGs) in order to solve the problems of energy wastage, energy control, uni-directional flow of information, growing energy demand, reliability, measurement and security. Smart grids increase the automation, coordination and connectivity between these electricity suppliers, electricity users and networks used in local distribution tasks and long distance transmission. Smart Grids offer bi-directional energy flow between elec...
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...
