Present State Analysis of Customers' Effect in Power Distribution System by Momentary Voltage Variation |
| Abstract |
This paper analyzes the present state of customers" effect in distribution system by momentary voltage variation. Customers are becoming increasingly concerned about the quality of electric power. Most of all, the voltage magnitude quality is very important because it can have a direct effect on customers. Especially, according to the development of automatic process, momentary voltage variations result in the shutdown of sensitive loads such as electronic equipment, computer and magnetic contactor, and so on. To analyze the shutdown rate of customers" equipments by the momentary voltage variation, we present the OBEMA curve and the cumulative OBEMA curve of each load type through the experiment for the customers" sensitive equipments. Also, we have surveyed customers" opinion by the questionnaire as "Survey of Power Quality" and then the results are reported. |
