Dynamic properties of bulk power interconnections

摘要

The paper describes changes in dynamic properties of the present-day bulk electric power systems (EPS) in the course of their development, on the basis of operating experience and numerous studies. The character, reasons and consequences of these changes are analysed. The dynamic properties of EPS are becoming worse leading to a decrease in the reliability of consumer supply. Consideration is given to the emergency control measures that reduce the negative consequences for consumers in such systems.
