AC Circuits and Power Systems in Practice

Mehr zum Buch

This essential guide combines power system fundamentals with practical aspects of equipment design and operation in modern power systems. Written by an experienced power engineer, it reviews key concepts and network theorems while delving into equipment design and application. Topics covered include basic circuit theorems, phasor diagrams, per-unit quantities, symmetrical component theory, and the roles of active and reactive power in network stability and voltage issues. The book analyzes magnetic circuits, reactor and transformer design, and the operation of step voltage regulators. It also introduces earthing systems in LV and MV networks, discusses the adverse effects of harmonics on power equipment, and addresses power system protection. European and American engineering standards are integrated throughout to familiarize readers with their application. Aimed at engineering students and recent graduates, the text features over 400 illustrations and offers a broad introduction to the subject, facilitating further study. Many industry examples bridge the gap between academic learning and industrial practice, aiding the professional development of graduates. The material is accessible, incorporating both mathematical and visual representations, with problems at the end of most chapters to reinforce practical applications of the theory.
