Are you fascinated by the complex web of electrical power that illuminates our modern world? Do you want to understand the intricate systems responsible for delivering electricity to our homes, businesses, and industries? Look no further than Electric Power Distribution System Engineering, Fourth Edition by renowned author Turan Gönen, revised and updated by Chee-Wooi Ten and Ali Mehrizi-Sani. This captivating book takes you on a journey through the fascinating realm of electric power distribution, offering a comprehensive yet accessible exploration of the engineering principles, technologies, and practices that underpin this vital aspect of our daily lives. Whether you're a curious non-specialist, an avid reader with a thirst for knowledge, or a librarian or bookseller seeking an invaluable resource, Gönen's masterwork will both enlighten and captivate you. An early leader in the academic market, this book provides an overview of classical planning for electric power distribution systems, which has been used for many years in designing and analyzing electric power distribution systems. The authors have taken a bold initiative to update the content, incorporating relevant aspects reflecting the advancements of today's evolving smart grid. Within its pages, readers will discover detailed discussions on the principles of power distribution, including the fundamentals of power generation, transmission, and distribution. The authors provide detailed explanations of the various components and equipment used in distribution systems, such as transformers, circuit breakers, switches, and protective devices. As part of the book, planning for the distribution network involves sizing and considering candidate geographical locations/regions in relation to the capacity of existing infrastructure, allowing for new additions to be built. For example, this includes locations either extending another feeder from distribution substations or building new distribution substations, depending on what makes more sense. Many assumptions have been made for non-existing distribution feeders to calculate ballpark figures for determining voltage profile and power losses if they were to be constructed. Readers will gain insights into how these considerations translate into net positive, net negative, or net-zero loads. All of these aspects can be gradually integrated with renewable energy sources, innovative grid technologies, and distribution automation over time. The authors involved in this book have made significant contributions to the state-of-the-art development by incorporating recent updates from the literature, thereby addressing the latest advancements. One remarkable feature of Turan Gönen's Electric Power Distribution System Engineering is its strong focus on practical applications and real-world scenarios. In addition to providing theoretical knowledge, the book also offers numerous examples that effectively bridge the gap between theory and practice. This unique approach enables readers to comprehend the intricacies of distribution system engineering and apply their newfound knowledge to solve complex problems in the field. By seamlessly blending theoretical foundations with practical insights, Gonen's book emerges as an indispensable resource for aspiring engineers, professionals, and researchers, as it offers a comprehensive understanding of electric power distribution systems and their practical implications.
