1977 Stability Considerations for Industrial Power Systems

Transient stability is assuming increasing importance in the design and operation of industrial power systems as trends toward large synchronous process drives and in-plant generation continue. Stability is the ability of a power system with multiple synchronous machines to survive disturbances such as faults, switching, and impact loading without losing synchronism. The stability of a system under specified disturbances can be examined by computerized transient stability studies, and various methods exist to improve stability levels if necessary.
