Voltage Sag Source Location Based on Instantaneous Energy Detection

Voltage sag is a major power quality problem, which could disrupt the operation of voltage-sensitive equipment. This paper presents the method based on variation components-based instantaneous energy for voltage sag source detection. Simulations have been performed to provide the thorough analysis for system with distributed generation units. The studies show that the presented method can effectively detect the location of voltage sag source.
