摘要：
This paper presents the main results of a work aimed at resolving voltage sags in customer substation, by measuring and analyzing the power quality problem. The work is based on a power quality monitoring system built in the customer substation. A large number of power quality events are recorded to pick up the voltage sag performance, the voltage sag characteristics and the number of sags is summarized. SARFI-curve method according to IEEE P1546 is used to analyze the sag influence on customer's sensitive electrical equipment. Combined with the specific situation, a set of solution to voltage sag problem is proposed to improve power conditioning for sensitive loads and reduce economy losses.
