Project Plan
Introduction:____________________________________
General Background
This project will consist of basic web functionality and design techniques. The userfriendly environment will provide concise information to the user. There will be a search
engine on the site that can break down the search item by different subjects, as well as by
the author and date of publication. This will provide the user with a more precise list of
search results. The stability program will be a user tool for the professional engineer. It
will not necessarily be as useful for a student because of the student’s lack of experience.
The stability program will display the results in an effective and efficient way.
Technical Problem
To accomplish this task, utilization of web design software and techniques will be
crucial. The search engine will have access to a database of books, papers, web pages,
etc. to provide the user with pertinent information relevant to subject of his or her choice.
The design of this web page will be accomplished through the use of html programming
1
in Microsoft FrontPage. All information and web design will be stored on a temporary
senior design server until ready to be commercialized.
Operating Environment
This site will be accessible from any computer that has internet access. With the evergrowing availability of the world wide web, this web page will be able to be viewed by
many people for professional and educational purposes.
Intended User(s) and Use(s)
The intended users of this site include student and professors of power engineering as
well as professional power engineers. Other electrical engineers may not have much use
for this site due to the fact that it is geared towards power system engineers. The students
who access this information will be assumed to have basic power analysis knowledge.
One use of this project will be to find information in a specific area of power system
security. The results will show where the necessary information may be obtained. These
results will include web pages, books, technical papers, magazines, and videos. The
second use of this project will be the access to a power stability program. Information
will be inputted by the user, which will be sent to the server to access the stability
program. Using this information, the program will calculate the necessary data and send
the output back to the web page for the user to analyze.
Assumptions
Because of the technical nature of this large-scale project, the user as well as the creator
must meet certain requirements in order to use this web site in an effective and efficient
manner.
· The user will have basic power analysis knowledge before using this web page.
· A server will be acquired that has adequate space to store all the web pages that will be
created, the database information that is provided and organized, and the programs to
create a web server. This web server needs to have the capability to run a database
server, HTML, Java, and other Java to FORTAN programs.
· The user will use SI units for all data that is inputted.
· The data that is outputted will also be in SI units.
Limitations
The speed of this web site will be a big factor in how efficiently it runs. In order to keep
the efficiency as high as possible, certain limitations will be set on the web site.
· The connection speed of the user will determine the speed of the software.
· The power system stability program will only be able to take in a 30-bus system.

Design Requirements:_____________________________
Design Objectives
These objectives are goals that need to be accomplished prior to starting the project. In
addition, these specific areas are discovered in greater detail while the actual project is
being designed
· Learn web-based programming languages such as Java, HTML, and FORTRAN.
· A web server that can hold information for web page, collection of information, and
web-based software.
Functional Requirements
These requirements are what define the final product. These are needed in order to test
the product so that it meets the defined requirements.
· The web page will contain the menus for information in several areas including: thermal
rating, transient stability, voltage stability, oscillating stability, frequency stability and
various power system stability areas. This will structure the collection of information
that has been compiled.
· The web-based software will display results from a simulation dealing with a wide
range of data based calculations. These can help determine under what conditions a
blackout may occur.
Design Constraints
Constraints are the bounds that need to be considered during the design of the project.
Such bounds allow the creation of a project that has a specific needed purpose.
· The amount of space on the web server that is not linked to information of other servers.
· Internet connection speed of the user to access large sized if necessary.
Measurable Milestones
Every project needs to know where it is at the current time. The following milestones
create a sense where the current project is and how much what needs to be accomplished
for the final product.
· Creating a pseudo homepage that can be applied to areas of power system stability.
· Hosting the homepage on a server so that people can access it from the Internet.
· Implementing the collection of information on the web page. This will allow users to
view data in an organized fashion.
· Adding a simulation of the web-based software so that users can view a simple
condensed version of the Java and FORTRAN programs.
3
· Perform successful test of final project.
End Product Description:__________________________
Web-based interaction over the Internet allows advanced, new generation applications
that can aid in understanding the various factors that lead to power system blackouts. The
web page involves a user-friendly graphical interface that helps users learn concepts of
power system security. The use of data files and option windows will allow the webbased software to simulate a variety of operating conditions that may lead to a system
blackout. An extensive database related to power system security will be accessible in a
way that the user can extract specific information related to a particular aspect of the
problem.
Approach and Design:____________________________
Technical Approaches
In every problem there are several solutions. To tackle the current project three ways
were investigated: write all the code from scratch ourselves, use commercial problems
and commercial software for all the code needed, or use the internet to find shareware
that will allow the project to be completed. Each way has it's own benefits and
drawbacks.
Technical Design
Below are the aspects of the project that need to be taken in consideration to accomplish
the project in a clear and concise manner.
· A search engine that will guide a local search of the information on power system
stability.
· A web page that will organize information in a user-friendly manner.
· A Java-based program that displays collected data from a power system network. This
program displays the outcome in a way based on the user’s preferences.
Testing Description
Testing the end product in an objective manner is the only way to know if the product is
user-friendly. In the early stages of development, the developers will self-test the website
for flaws in areas such as the search engine and accessibility of links to other pages. One
major user will be that of the client. The client will be asked for feedback on the web
page design and web-based software to see if they meet the client’s needs. Once the end
product is ready for public use, users will be given a chance to input their feedback via an
email link to a webmaster of the web page.

Risks and Risk Management
Problems can occur in the stage of development of the end product. Such problems
include the loss of any group member, problems in debugging code, cost of commercial
software, loss of a server, and any sort of internet related problems. To reduce these
problems, measures need to be taken in the early stages of development. We will set
goals that can be met every week and achieve them. Since there are four members, it is
likely that one member will have a solution for a given problem as long the issue is
looked at as soon as possible. These are a few ways that these problems can be reduced.
Financial Budget:________________________________
Shown below in Table 1.1 is the estimated time that each member will spend over the
next eight months in order to meet the team goal. The column of web page design
includes all aspects of designing, which range from creating to testing of the web page
itself.

Summary:______________________________________
The idea of power system stability is a complicated and difficult subject to understand.
With the help of this web page, users will be able to access various documents and
software to help them understand this topic better. The page will provide the user a tool
that will aid in analyzing many real-world systems. Because of the complexity of this
web site, this project may take longer than first anticipated. We will, however, complete
the voltage stability portion of this project, depending on the time frame, add the
additional parts of power system security after that. Most of the information needed to
make this web site has already been obtained. The task set forth to us is to organize this
information in an effective manner. Once the procedure has been set from the voltage
stability aspect, the other parts of this web page should progress more rapidly. Once
completed, this web site will help professional engineers as well as engineering students
and professors for years to come.
