The book starts from the existed problems in fault analysis of the lumped-parameter circuit model. It firstly introduces the basic electromagnetic phenomenon, uniform transmission line guided electromagnetic waves, multi-conductor system guided electromagnetic waves, fault generated travelling waves; then it introduces series of the traveling waves based protections, which includes principle, technology and application in practical power grid; it also discusses the travelling waves based fault location and the travelling waves based fault feeder selector in China. It systemically reveals the essential features of the fault traveling wave and concludes the analytical solutions of the transient fault traveling waves and the modulus maxima representation of the dyadic wavelet transform of fault traveling waves. Finally, the book analyzes the acquisition of traveling waves and the sensor’s characteristics. A unique fault travelling wave test device has been invented based on the theories of the book and will be applied in real systems.

System protection is laid between the defenses for power system protective relaying and the emergency control. Under the premise of ensuring the safety of electrical equipment, it strives to ensure the safety of the system, block the chain of occurrence and growth of cascading faults, and effectively avoid the occurrence of large-scale blackout catastrophes. This book systematically elaborates on the dealing technology of a special type of fault, the “cascading fault”, in the AC-DC hybrid large-scale power grid. The main contents include immunization distance protection for accident overload; distance protection that is immune to oscillation; inverter control technology to prevent long-term or continuous commutation failure; DC participation emergency power flow control technology used to share the accident transfer overload caused by inverter lockout; and overhead transmission line adaptive overload protection.The basis of English translation of this book from its Chinese original manuscript was done with the help of artificial intelligence (machine translation by the service provider DeepL.com). A subsequent human revision of the content was done by the author.
