Introduction to Power Systems and Electrical Equipment

Author: Liu Boqing
Publisher: Wuhan University Press
Book Description:
This book primarily covers the basic knowledge and fundamental principles of power engineering, power plants, and the electrical components of substation (distribution substation). The book is divided into 5 chapters, including an overview of power systems, the function, working principle, structure, and selection of major electrical equipment, requirements and connection forms of primary and secondary electrical circuits, as well as the layout of electrical equipment.
This book can serve as a teaching material for students in professional fields such as water conservancy engineering, hydropower engineering, hydrology and water resources, port and waterway engineering, among others, as well as for non-electrical undergraduates and graduates. It is also suitable as a reference for technicians engaged in the operation, management, and design of electrical equipment. Additionally, it can be used as a teaching material for adult education programs, including correspondence universities, television universities, evening universities, and self-study examinations. Furthermore, it can be used as a training textbook for basic knowledge for power engineering technicians.
