Fast Search of Key Lines in Power Flow Transferring Based on Path Search in Multi Voltage System
A method for fast search of key lines in power flow transferring based on path search in multi voltage system was put forward.When a line was overload, find the K shortest paths between the two side nodes before the backup protection acted.Estimate the power flow transferring distribution coefficient and the overload dangerous coefficient to search the key lines in power flow transferring.The value of K was optimized through theoretical analysis and the overload dangerous coefficient could reflect the effect of voltage level on power flow transferring.This method is simplc and accurate, with less computation and a fast searching speed, which is verified in IEEE39 bus system.
