A Distributed Control System Application
No full textobjective of this project is to link and monitor the data of the two processes through a Local Area Network (LAN) using TCP/IP over Ethernet,The Second Objective is to give Server the ability to set some privileges restrictions for both Clients (processes interface),The third objective is to send some remote control commands from Server to client 2 through the network.Distributed Control Systems are systems which contain a large number of interconnected devices that exchange data through communication networks. DCS offer the advantage of centralized control, while retaining the capability of distributed or local control. True distributed control systems use localized control, which is in turn controlled by the operator located at a central location. The performance of DCS depends not only on the operation of the individual components, but also on their interaction and cooperation, mainly Integration between software and hardware. The contents of this document present a review of DCS. Moreover delivers an intro to computer networks and visual basic language as DCS success key lays between networks topology and software interfaces. Finally a DCS application is provided through VB as a software interface and Client-Server network model. Showing design methodology, Test run and results acquired as well as programming code developed
HARMONIC TREATMENT IN INDUSTRIAL POWER SYSTEM
No full textThe objective of this project is present general characteristics of the harmonics, harmonic indices and measure of the distortion of the wave.,To present the harmonics sources and explain the harmonics effects in the different components of an industrial system. , To study the methods those are used in harmonic analysis and scenarios of harmonic mitigation. , Take a case study for harmonic analysis using simulation program. If the distortion exceeds the acceptable limit mitigation must be done.Power system networks that have a distorted voltage and current waveforms are said contain harmonics. This distortion may cause a failure in customer equipments. In the modern era, the distortion can no longer be ignored due to increase in the equipment that sensitive to wave variation and devices that produced harmonics. In this project the sources of harmonics and their effects in power system equipments are illustrated with the methods that are used to analyze and mitigate it. The Sudanese- Malaysian steel factory network was investigated using ETAP simulation program as a case study. And the results of harmonic analysis were compared with IEEE limits. It was found that the total harmonic distortion limit for current in the simulated case study network exceeded the limits. The harmonic mitigation solution chosen was the passive filter and the method of the design is included in the project. The process of mitigation is successfully completed and the distortion become within IEEE limit for the Sudanese – Malaysian factory network
THEATRE LIGHTING CONTROL USING DMX512 STANDARD
No full textIn this project, a software based theatre lighting control system using DMX512 protocol was implemented. The system was simulated using two standard personal computers (PCs). One is simulating the controller and the other is simulating the intelligent lighting fixture. The software for the system was special dedicated software or this purpose.In the world of theatre, the theatre stage lighting plays an important basic role in making a better understanding of the scenes as it is establishing or altering the position in time and space, directing the audience attention to an area of the stage or distracting from another. It is also the basic tool for changing the audience mood as it is used as well to create a huge effect on the audience's senses and to evoke their emotions. For this purpose some lighting control protocols were invented so as to control intelligent lighting fixtures which can change their (colour, movement in X-axis or Y-axis, and many other parameters). In this project, a software based theatre lighting control system using DMX512 protocol was implemented. The system was simulated using two standard personal computers (PCs). One is simulating the controller and the other is simulating the intelligent lighting fixture. The software for the system was special dedicated software or this purpose. On the other hand the system was implemented successfully on a hardware intelligent lighting fixture, as it's been able to control all the available fixture parameters efficiently using a personal computer as the controller connected directly to the intelligent fixture. The actual running data was also recognized; the data packets that carrying the DMX512 data were separated. Also a general understanding of the structure of the data packets of both the controller and the receiver data packets was developed
IMPLEMENTATION AND ANALYSIS OF FORWARD ERROR CORRECTION TECHNIQUES
No full textThe aim of this project is to design and construct an encoder and decoder for RS codes. FPGA is the recommended hardware platform. Learning outcomes: Learn what the types of error correcting codes are and how they operate. Understand the parameters and limitations of error correcting codes. Gain a deep understanding of the encoding and decoding processes. Design and implement a system to achieve the encoding and decoding. Learn how to implement a system on an FPGA.In the current world, communication has got many applications such as telephonic conversations. in which the messages are encoded into the communication channel and then decoding it at the receiver end. During the transfer of message, the data might get corrupted due to occurrence of lots of disturbances in the communication channel. So it is necessary for the decoder tools to have a function of correcting the error that might occur. Reed Solomon codes are type of burst error detecting codes which has got many applications due to its burst error detection and correction nature. The aim of the project is to implement this reed Solomon codes in a Spartan 3AN FPGA Starter kit (supported with XC3S700AN). To accomplish this check one can start with calculating read Solomon code by hand and then going for simulation in XILINX writing the VHDL code. The encoder and decoder design of reed Solomon codes have got different algorithms. Based on your requirements you can use those algorithms. The difference between the algorithms is in the calculations methods used within them. The complexity of the code depends on which algorithm used. The simulation result of vhdl codes is constituted in ModelSim simulator

Electrical Power Distribution Losses in Sudan
No full textThe objective of this project is to define the main sources of electrical transmission and
distribution losses in power system especially in Sudan. And to find out proper solutions to
reduce or eliminate these losses and provide electricity in the most sufficient way.Power losses in electrical system referred to the difference between the magnitude
of power generated and power consumed. The need for reducing electrical power
losses either in transmission or distribution is came from the high cost that the
utilityincurs. There are two causes of distribution losses, technical and nontechnical.
The causes of each one of them were investigated in this project and
corresponding solutions to reduce them were adopted.
ETAP software program used as simulation program in this project to simulate the
case of technical losses which is helpful in understanding and analysis this type of
losses. In the other hand since no programs or techniques were able to determine
non-technical losses, a real data provided detailed information to give a clear
glimpse about non-technical losses.
This project objectives successfully met by obtaining the major causes of
distribution losses in Sudan and finding out the optimum solutions
Fingerprint Entering System
No full textThis project developed a fingerprint based access control system that assures the security of a door of room or building by means of limiting the access to that room or building to specific people.Fingerprint has been used as a biometric feature for security reasons for centuries. A much broader application of fingerprints is for personal authentication, for instance to access a building, a computer, a network, a bank-machine, a car, or a home. It is preferred over traditional methods and other biometrics due to the relatively low cost; it is small size, universality, high performance and ease of integration of fingerprint authentication devices. In our project we developed a fingerprint based access control system that assures the security of a door of room or building by means of limiting the access to that room or building to specific people. This target can be mainly decomposed into Enrollment stage (scanning a sample fingerprint), image preprocessing, feature extraction and feature match. The fingerprint management system represented by a simple personal computer (PC) and the program is coded by MATLAB7. The characteristics of a fingerprint image extracted by Feature Extractor (soft ware), compared to characteristics of reference fingerprints in a database by a matcher (soft ware) to determine proper identification of a person for verification (Authentication stage). If this person is authorized the matcher send signal through the parallel port to open the door lock which we simulated it by a relay, if he is unauthorized the matcher will get an alarm warning us that an intruder trying to get in. The system performance is shown by experiments conducted upon a variety of fingerprint images. Also, the experiments illustrate the key issues of fingerprint recognition that are consistent with what the available literatures say
