Abstract: Voltage collapse phenomenon is known to be complex and localized in nature but with a widespread effect. The ultimate effect of voltage collapse would be total system collapse which would incur high losses to utility companies. Thus, on- line monitoring of power system stability has become a vital factor for electric utility companies. One of the methods to avoid voltage collapse is to perform Under Voltage Load Shedding (UVLS). Fast Voltage Stability Index (FVSI) index is proven to be a good indicator for voltage stability in a system. This paper analyzes the correlation between FVSI and the placement of UVLS relays for a 746 test bus system. It is found from the simulations results that FVSI index can be used as an indicator for the placement of UVLS relays in a power system network. ©2009 IEEE.
