Electrical Generation And Distribution Systems And Power Quality Disturbances PDF Download

Electricity generation is the first process in the delivery of electricity to consumers. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire, or disc of copper between the poles of a magnet. Before Michael Faraday had discovered his famous law of electromagnetic induction, battery were the only source of electric power. After that, DC generator was developed, but it could produce only a few hundred volts of electric power and naturally this low voltage power could not transmitted efficiently to a large distance. In the latter half of eighteen centuries, AC electric power generation, transmission and distribution came into the picture. In an AC system, it became possible to step up voltage of electric power to desire level for efficient transmission to a long distance. After that 3-phase induction motor was developed which was much simpler in construction. Generation, transmission and distribution of AC power were much easier than DC power; hence very fast AC power system became the most popular means of electric power. Electricity is most often generated at a power station by electromechanical generators, primarily driven by heat engines fueled by chemical combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power and electrochemical batteries. Additionally, the presence of a static converter as output interface of the generating plants introduces voltage and current harmonics into the electrical system that negatively affect system power quality. By integrating distributed power generation systems closed to the loads in the electric grid, we can eliminate the need to transfer energy over long distances through the electric grid. This book, Electrical Generation and Distribution Systems and Power Quality Disturbances, reveals the different power generation and distribution systems with an analysis of some types of existing disturbances and a study of different industrial applications such as battery charges.
