Electric power systems have become much more complex in the past years, owed e.g. to distributed generation and the intermittency of renewables. This complexity makes it potentially more vulnerable. However, use of information technology also helps detecting errors and problems, and preventing and correcting them.
This is the second edition to the comprehensive introduction to protection of electrical power systems using computer-based methods (i.e. digital relays). The treatment is logically structured, covering mathematics and principles for the development and implementation of the major algorithms underlying different protection techniques. They can be applied to protection of generator transformers, lines, switchgear and cable circuits: the main components of transmission and distribution systems.
The new edition offers revised and updated chapters, and comprehensive additional material including wavelet and S-transformation, recursive least square technique, system identification techniques, travelling wave-based protective scheme, and protection of networks with integrated renewables.
