Abstract In this thesis a method based on Particle Swarm Optimization (PSO) algorithm, which represents one type of modern optimization techniques is presented to determine the optimal parameters of Power System Stabilizers (PSSs) found in Sudanese National Grid, instead of classical control approaches. In addition TCSC is implemented in the National grid to increases the performance of the system by decreasing reactance of the transmission lines and hence increases the power flow in the lin...
ABSTRACT In this research the equalization concepts in Long Term Evolution (LTE) has been discussed in theoretical and practical manners as an analysis and implementation study of channel equalization in LTE downlink. As channel equalization is achieved on the receiver side after the OFDM modulation , we proposed a complete scenario for generation of OFDM frame from random bits which symbolized and QPSK modulated to generate the OFDM frame which consist of 10 sub frame, then the frame is pass...
Abstract Picking and placing an object or products in specific place or boxes play an important part in industry process, it consumed a lot of time also need patience and accuracy and cannot handle any mistakes. Pick and place robot is a robot that can be programmed to pick product or any object and place it somewhere. these robots are popular among many automation applications and material handling system, they are especially practical in applications where repetitive and difficult tasks ne...
ABSTRACT The purpose of Maintenance is to extend equipment life time or at least the mean time to the next failure. Asset Maintenance, which is part of asset management, incurs expenditure but could result in very costly consequences if not performed or performed too little. It may not even be economical to perform it too frequently. The decision therefore, to eliminate or minimize the risk of equipment failure must not be based on trial and error as it was done in the past. In this thesis, ...
ABSTRACT This study pursuit develop solar energy systems in the light of technological advances to develop these systems, especially those moving (solar Tracking) to take advantage of sunlight for a longer period. The Objective of Thesis is to find a design of the sun Tracker with two axes follow the movement of the sun throughout the sunrise to take advantage of the rays and solve the problem of environmental factors and the alternation of night and day to produce the greatest amount of sol...
ABSTRACT Power system stabilizers and other controllers are employed to damp oscillations in power systems, thereby guaranteeing satisfactory dynamic performance following major network disturbances. However, the parameters of these controllers are often tuned based on the power system linearized model which generally is a function of the system operating point or state. These controllers suffer from poor performance when the system state changes. The aim of the research work reported in thi...
ABSTRACT This thesis presents a neuro-fuzzy controller design for speed control of Direct Current (DC) motor. The thesis scope includes the simulations and modeling of DC motor, Fuzzy Logic Controller (FLC), neuro fuzzy controller and conventional Proportional-Integral-Derivative (PID) controller as benchmark to the performance of fuzzy system. The most commonly used controller for the speed control of DC motor is the conventional PID controller. Fuzzy logic controller and neuro-fuzzy contro...
Abstract Over the past several years, the Internet environment has become more complex and untrusted. Enterprise networked systems are inevitably exposed to the increasing threats posed by hackers as well as malicious users internal to a network. IDS technology is one of the important tools used now-a-days, to counter such threats. The goal of intrusion detection is to identify unauthorized use, misuse and abuse of computer system insiders and outsiders penetrators. Various IDS techniques ha...
ABSTRACT In this study, a nonlinear dynamic model for large scale fossil fueled boiler turbine power generation units is presented. The challenge in controller design for these plants exists because they are typically nonlinear and multi-variable with multiple control objectives. This thesis presents the application of a fuzzy logic based controller for boiler turbine plant to control the drum pressure, power output and water level. Fuzzy control system have been successfully applied to a wi...
Abstract Wireless charging through inductive coupling could be one of the next technologies that carry the futures forward. In this study it has been shown that it is possible to charge low power devices wirelessly via inductive coupling. It minimizes the complexity that arises for the use of conventional wire system. In addition, the thesis also opens up new possibilities of wireless systems in other daily life uses. Much interest in the research has been conducted to determine the feasibili...
ABSTRACT Maintaining power system security of large power system is one of the challenging tasks to have secure operation point. The security assessment is an essential task as it gives the knowledge about the system state in the event of a contingency. Contingency analysis technique is being widely used to predict the effect of outages like buses, transmission lines, generators and inter-bus transformers, these may cause transmission line over loading and bus voltage limits violations. A...
Abstract Using communication signals for radar applications has been a major area of research in radar engineering. In the recent years, due to the widely available wireless signals, a new area of research called commensal radars has emerged. Commensal radars use available wireless Radio Frequency (RF) signals to detect and track targets of interest. This is achieved by placing two antennas, one towards the transmitting base station and the other towards the surveillance area. The signal rece...
ABSTRACT The main focus of this study is to evaluate whether load following operation can be performed using the existing South African nuclear power plant. Of which, knowing that will assist in determining whether the addition of load following capabilities on the planned nuclear fleet is justifiable or not. In this report the relevance of Koeberg Nuclear Power Plant to adapt to the demand is examined and the effects on plant operation simulated. The report analyses the operation of the exi...
Abstract A 3-phase Z-source inverter has been researched, designed, simulated, built and tested. The purpose of the inverter is to deliver 3-phase 400 VAC from a DC supply that can vary over a range of 20 to 70 Vdc. This is done with a Zsource inverter topology which is a single conversion method with no additional DC to DC boost converter. A novel DSP control algorithm allows the inverter to achieve the following: · Run Space Vector Pulse Width Modulation (SV-PWM) for maximum DC bus voltag...
Abstract Fractal image compression is a comparatively new technique which has gained considerable attention in the popular technical press, and inore recently in the research literature. The most significant advantages claimed are high reconstruction quality at low coding rates, rapid decoding, and "resolution independence" in the sense that an encoded image may be decoded at a higher resolution than the original. While many of the claims published in the popular technical press are cle...
