主　　题：Area of vulnerability(AOV) false position method(FPM) fault location detection(FLD) power quality voltage sag monitor(VSM). 

摘      要：The increase in the number of sensitive loads in power systems has made power quality,particularly voltage sag,a prominent problem due to its effects on consumers from both the utility and customer ***,to evaluate the effects of voltage sag caused by short circuits,it is necessary to determine the areas of vulnerability(AOVs).In this paper,a new method is proposed for the AOV determination that is applicable to large-scale *** false position method(FPM)is proposed for the precise calculation of the critical points of the system ***,a new method is proposed for the voltage sag monitor(VSM)placement to detect the fault locations.A systematic placement scheme is used to provide the highest fault location detection(FLD)index at buses and lines for various short-circuit fault *** assess the efficiency of the proposed methods for AOV determination and VSM placement,simulations are conducted in IEEE standard *** results demonstrate the accuracy of the proposed method for AOV *** addition,through VSM placement,the fault locations at buses and lines are detected.
