DC-DC Converter for Fuel Cell Application
No full textEngineering Invention & Innovation Exhibition (ENVEX) 2010 organized by Student Affairs & Alumni Department (HEPA), Universiti Malaysia Perlis (UniMAP) with collaboration Ministry of Higher Education Malaysia (MOHE) and Ministry of Science & Technology Innovation (MOSTI) , 2nd - 4th April 2010 at Khoon Aik Hall, Kangar, Perlis.Nowadays, the interest for green energy source for domestic used has increased rapidly. The source can be either renewable energy like solar and wind or alternative energy like fuel cell. Currently, the fuel cell has been used as energy source in many application such as in hybrid car, vending machines, vacuum cleaner and high road sign. Fuel cell output voltage is varied wisely and low in magnitude (<60V for a system<10KW). Therefore, the step up DC-DC converted is essential to generate DC voltage. The main purpose of this project is to develop a high efficiency DC-DC converter for fuel cell application. This converter will boost up the DC input voltage to more useful high DC voltage. This high votage can be used to power up DC devices or can be used as an input for DC-AC converter. This converter produce low ripple for output current and voltage which cause low harmonics and noise produce by the device
Development of wind-electric prime mover using roof ventilator turbine
No full textAccess is limited to UniMAP community.This project is about the development of wind electric prime mover using roof ventilator turbine. The roof ventilator used in this project is a vertical axis type of turbine and will be used as wind turbine to drive the generator rotation. Roof ventilator is basically use as the tool to help air circulation inside building or houses. The main objective of this project is to increase the ventilator ability as a turbine and it a one step further to generate
clean and renewable energy. The only weakness of the ventilator as a wind turbine is the transient speed. Basically, generator needs to be turn at high and constant speed to get enough electric power. To enhance the ability of this ventilator as a turbine, a gear system is studied and developed for this reason. The type of gearbox that has been developed in this project is increasing speed type and will be connected between the ventilator and the generator. With this gearbox, it will dramatically increase the speed and thus make the generator generate more electric even when the ventilator spins at low speed. Because of the transient speed of the ventilator, the speed at the output shaft of the gearbox is also transient. The generator still generates more electric with the gearbox help but the output is also transient when different speed is applied at the generator. Thus make the output voltage not suitable to be used. To make the generated voltage stabilize, a regulator is
needed. The regulator is use to make the output voltage always at a constant value. To
make the system more effective, the output from the generator and regulator will be not
directly use to electrical appliance. The output voltage will be used to charge a battery and the output from the battery then can be used any time when the battery is fully charge
Computer aided education on protection system
No full textComputer Aided Education (CAE) presents a host of new opportunities for institutions to improve educational outcomes. Computer aided education can be used in teaching and learning module in a whole range of ways including on protection system. This project aims is to develop a new teaching module for undergraduate students and also for those who involve directly or indirectly in power engineering system which used computer aided education (CAE) to support students’ learning. The project is designed to enhance the learning and teaching method for protection system using computer aided
education. Due to the project, the protection system will be focus on the basic equipment of the protection system on power engineering system. A protection system has three basic equipments. There are instrument transformers, relay and circuit breaker. The
develop software will assist students to understand about the equipments of the protection system interactively. The software is developing using Macromedia Flash 8.0
Impedance bus matrix formulation tutorial software
No full textAccess is limited to UniMAP community.The bus impedance matrix is an excellent network description use in the solution
of faulty networks. Unlike traditional network analysis, a bus impedance matrix usually
used simplified notation such as a one-line diagram and per-unit system, and focus on
various forms of AC power such as reactive, real, and apparent power rather than
voltage and current. Even though it is easy to use bus impedance matrix for fault
computations, the bus impedance matrix is not easy to form. One difficulty associated to
build the bus impedance matrix is the ordering of primitive elements. There exist a lot of
software implementations of power network studies. The great importance of bus
impedance matrix is analyzing faults of an existing power system network, which also
indirectly planning the future expansion of power systems as well as determining the
best operation of existing systems. The principal information obtained from bus
impedance matrix is the formulation to compute faults of a power system network. This
project is mainly concerned on Kron Reduction method, where the formulations of Kron
Reduction use to develop a program that will reduce the bus impedance matrix back to
its original pxp order in the process of finding a bus impedance formulation. In this
purpose, Visual Basic 6.0 software is used to provide graphic user interface (GUI) for
the user to enter the desired number of buses impedance data at computer. Besides, it
also shows a Zbus matrix and will produce the simplest Zbus matrix at the end of
program calculation. Through the project, it can be concluded that development of bus
impedance matrix using Visual Basic 6.0 can solve impedance matrix up to infinite
buses easily and faster

Menu driven intelligent tutoring for power system modeling
No full textLink to publisher's homepage at http://www.myiem.org.my/The Graphical User Interface (GUI) provides the user with interactive visual communication to analyse and model the power
systems. Applying the advantages of the GUI, new menu driven intelligent tutoring system was developed. The software allows
the user to draw the single line diagram representing the power system with ratings of each component. The software
calculates the corresponding per-unit values and the change of impedance of individual component referred to the common
system MVA. These per-unit values can be used to draw the reactance diagram of symmetrical components automatically.
Therefore, it becomes a convenient approach for creating an interactive tool in teaching and learning the power system. The
aim of this project is to make teaching and learning more productive and efficient by employing modern technologies. It is
hoped that this software will enhance the learning process and make it more interactive, interesting and user friendly
