This book presents the meaning of electric basics for electric stations. It discusses the major components electric connections inside a station. The classification of connections for different types of stations is analyzed. The types of power stations and substations are classified in details and the main contents on the single line diagram of a station are illustrated. The principle of the design of stations is given where the layout design is investigated in details. The transient profile between transmission and distribution borders is deduced. The renewal energy generation and connection with networks presented with classifications. The costing and energy pricing are delivered. The transmission lines are studied well and the towers are grouped for illustration. The book is a simple tool for graduate and post graduate students. It is a useful reference for electric engineers, researchers and designers.
