Protective Relaying For Power Generation Systems

Reimert (a registered professional engineer) describes the major electrical protection schemes associated with synchronous generators and induction motors. He presents basic principles and criteria alongside more detailed derivations of complex system interaction that provide a basis for understanding the rule-of-thumb criteria and are often also useful for post-incident analysis. The discussion also includes analysis of the damage and damaging mechanisms related to each protective function. Chapters cover generator normal operations, generator short circuit calculations, generator differential relay, backup fault protection, generator ground fault protection, unbalanced current protection, motoring protection, field winding protection, overexcitation, abnormal frequency protection, minimum excitation limiter, loss of synchronism, loss of field protection, synchronization protection, accidental energization protection, and motor protection.
