Cj. Melhorn et al., VOLTAGE SAGS - THEIR IMPACT ON THE UTILITY AND INDUSTRIAL CUSTOMERS, IEEE transactions on industry applications, 34(3), 1998, pp. 549-558
This paper describes the impact of voltage Sags on the utility and ind
ustrial customers. Several utility measures are presented to minimize
the customer's exposure to voltage sags. These measures cannot complet
ely eliminate the impact of voltage sags on sensitive equipment, howev
er. A case study is presented in this paper that includes measurement
results that were used to characterize the voltage sags experienced on
the utility system and in the industrial facility, Simulation results
used to develop ''area-of-vulnerability curves'' for the industrial f
acility, mitigation equipment that was employed to improve the sensiti
ve equipment's ridethrough capability, and the lessons learned from th
e systems approach analysis are presented.
