The Development And Design Of A Database Driven Electrical Power Distribution Information System (PDF/DOC)
The study aims to develop a computerized electrical power distribution monitoring system. The system is designed to aid in the recording of electrical power bills of customers and to also collect their complain over the use of the power being discharged in their area. The study will also serve as a useful reference material to other researchers seeking related information on the subject. The research methodology used in the development of the system was analyzed and design methodology (OOADM) applied Object Oriented Analysis and Design in the analysis and design software engineering approach that modeled a system in the object point of view. The data used for the system development was gotten from the internet, textbooks and articles. The proposed system is such that the customers are registered and then the power distribution billings record is computed and saves to the data based.
1.0 Introduction
This chapter presents the introduction to the study. It presents that theoretical background, statement of the problem, aim and objectives of the study, significance of the study, scope of the study, organization of the research and definition of terms.
The use of computer (information technology) in electric power monitoring and control is vastly gaining organization acceptance. The monitoring system starts from data collection (meter reading). Monitoring or inspection carried out to get meter reading from customers” homes transformer status at various locations, to fault detection, such as electric cable condition and soon. These monitoring processes are either manual or partially automated, and as such associated with errors which cause inaccuracy and unreliability. The computer aided monitoring devices eliminate errors due to human limitations, preserve data effectively and alleviate complaints from aggrieved customers.
1.1 Theoretical Background
There is a glaring need for the utilization of information Technology (IT) and computing potential in revolutionizing the nation’s mode of power management and principals. This will serve as a vehicle for the drive toward a fully automated or computerized power monitoring processes. It will also provide the needed solution to most of the challenges resulting from the existing system which is potentially computerized. In this study, the design of a computerized power monitoring system is offered to foster the drive toward the full computerization or automation of the processes in the power sector fact that the full automation of processes in the power sector is the best for our economy, as it calls for the development of computer experts in the sector.
1.2 Statement of the Problem
Some problems associated with the existing partially computerized system are as follows:
Delay of bill dispatching to customers
Generation of accurate computed bills is below average.
Ineffective power monitoring
Low level of the security as files are easily misplace or taken away.
1.3 Aim and Objectives of the Study
The aim of the study is to develop a computerized electrical power distribution monitoring system. The following are the specific objectives:
To design a system to aid in the recording of electrical bill of customers.
To design a system that will be used to compute electrical power bills.
To create a system that can be used to update the bill record of customers.
1.4 Significance of the Study
The successful implementation of this research project will show a computerized system that can be used to record and compute electricity power bills. The study will also serve as a useful reference material to other researchers seeking related information on the subject.
1.5 Scope of the Study
The scope of this project will cover the development and design of a database driven electrical power distribution information system to be utilized by the operators of the different electricity distribution company (EDE) power plant grid supplying electricity to the Nigerian community.
Inasmuch as this project is intended for use in state, community in Nigeria the focus of this research will be limited only to PHCN
1.6 Organization of the Research

Chapter five focuses on the summary, constraints of the study, conclusion and recommendations are provided in this chapter based on the study carried out.
1.7 Definition of Terms
Electricity:
Electricity is the science, engineering, technology and physical phenomena associated with the presence and flow of electric charges. Electricity gives a wide variety of well-known electrical effects, such as lightning, static electricity, electromagnetic induction and the flow of electrical current in an electrical wire. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.
Electric Grid:
An electrical grid is an interconnected network for delivering electricity from suppliers to consumers. It consists of three main components:
Power stations that produce electricity from combustible fuels (coal, natural gas, biomass) or non-combustible fuels (wind, solar, nuclear, hydro power);
Transmission lines that carry electricity from power plants to demand centers; and
Transformers that reduce voltage so distribution lines carry power for final delivery.
Smart Grid:
A smart grid is an electrical grid that uses computers and other technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.
Summary, Conclusion and Recommendation
5.0 Introduction
This chapter presents the summary, conclusion, constraints of the study and offers useful recommendations.
5.1 Constraints of the Study
In carrying out the research work, some challenges were faced that limited the study such as:
Time:
The time given for the completion of the research work was too short hence the researcher had speed up the research work to meet up and this has an impact on the study.
Limited Materials:
Few materials were found pertaining to the research area and this limited the bulk of the literature review.
Finance:
The high cost of textbooks, internet browsing and transportation to different libraries to gather materials stood as a constraint to the research work.
5.2 Summary
Monitoring the distribution of power in PHCN entails a great deal of precaution and specification. It is required that for every customer that accumulates a bill within a particular period that the bills are paid off before the next period or their power is being disconnected. Computing and storing this information requires less error occurrences or there will be misrepresentations. Computerized power monitoring system is a computer-based system that aids the control of these information and stores the in a logically designed system. The system is used to compute the bills of customers and to also collect their complain over the use of the power being discharged in their area. The new system intend to replace the old manual system that consist of different errors.
5.3 Conclusion
Using an automated system should be the pursuit of any standard firm that intends to manage information in their company. An automated system constitutes different advantage that makes business today turn to its method of operation. Managing the distribution of electric power is only but one of the areas where Information technology is useful, numerous others abound. It is therefore for good that any firm should adopt this measure.
5.4 Recommendations
The following are the recommendations made for the use of the new system:
The staff of PHCN should be trained on the use of the new by a professional.
The programmer of the system or a reliable professional should be employed to maintain the system from time and to also update the system
A reliable network should be built that will ensure even distribution of the software suit to different offices in the firm.
More computer devices should be purchased and placed in the offices.
Customer should be educated on new changes that may have occurred due to the implementation of the new system.
Backup systems should be created for the database of the system to avoid unnecessary loses of important information.
