A METHOD TO DETERMINE THE RELATIVE LOCATION OF VOLTAGE SAG SOURCE FOR POWER QUALITY DIAGNOSIS

Abstract Event source locating is very important to improve the power quality level. And it is a helpful way to find the location of the power quality event source to determine the direction of event at each monitor. This paper presents a method to determine the relative location of the source of voltage sag. For this, the relative location of the source is defined first. Then, the main causes of voltage sag are classified and their characteristics are discussed, respectively. From these investigations, the rules to determine the relative location of event source for each cause are proposed and the overall algorithm to identify the relative location and the kind of event source is organized. Finally, the proposed method is applied to the IEEE 13bus test system and it is verified that the method can be helpful to pinpoint the accurate location of the event source.
