| Summary: | This paper presents a method to determine an area of vulnerability in power system using voltage sag analysis. The voltage sags and momentary power interruptions are among the most important power quality problems affecting industrial and large commercial customers. It may cause sensitive equipment to trip. Voltage sag analysis was used to determine the voltage sag characteristic, such as the level of the voltage sag and area of vulnerability. In this study, the fault position method is used to determine the area of vulnerability in terms of voltage sag. This report present ah area of vulnerability due analysis of the voltage sag which takes consideration of apply the fault at a bus and chance in the load buses. For this analysis, power system analysis toolbox (PSAT) software was used to evaluate the voltage sag. Also fort this analysis, time domain simulation is used to obtain the results. |
