ANALYSIS OF POWER QUALITY PROBLEMS IN SOLAR POWER DISTRIBUTION SYSTEM
L (A CASE STUDY OF COMPUTER SCIENCE ND SOFTWARE LAB) CHAPTER ONE INTRODUCTION 1.1 BACKGROUND TO THE STUDY The use of renewable energy increased greatly just after the first big oil crisis in the late seventies. At that time, economic issues were the most important... Continue Reading
Abstract Electronic devices comprising of non-linear components (diodes, transistors, transformers, etc.) produce some number of harmonics in our power systems creating various voltage distortions [7]. As a result, several technical problems may arise for the device such as overheating and damage to sensitive equipment which would most likely lead... Continue Reading
CHAPTER ONE INTRODUCTION The quest to satisfy our need for stable power supply in Nigeria has driven most Nigerians into an ardent search for alternative renewable power sources. One of such major renewable power source in use is solar energy, which is energy obtained from the radiation of the sun. To obtain electrical power from the sun, four key... Continue Reading
ABSTRACT The 200W solar system was determined by load assessment, solar panel number determination, battery requirement and then inverter sizing. A complete solar panel rated at 200w was however purchased, together with 2 no. 150A solar battery, 1500W inverter and also 10A charge controller.... Continue Reading

ABSTRACT Automatic gate is one of most usefully thing to use in companies, colonies, collages, homes, and schools. There is some type to operate a gate such as a sliding on screw or on rack and pinion, piston operated, rotary. Design is available for some type of operation and it is most costly also When installation and maintenance cost is not... Continue Reading
CHAPTER ONE GENERAL INTRODUCTION 1.1 INTRODUCTION The importance of electricity in the higher institutions of learning cannot be overemphasized. However, Electrical Power Generation in many universities in Nigeria is self generated by the institutions as the... Continue Reading
ABSTRACT The basic idea deals with detecting the voltage collapse ahead of time to provide the operators a lead time for remedial actions and for possible prevention of blackouts. To detect cases of voltage collapse, pattern recognition in conjunction with power system simulator for engineering (PSSE) program was created and then ... Continue Reading
