To solve the difficulty that existing analysis methods cannot get complete analytic solution of fault-induced travelling-wave on transmission line, an analysis method is presented in this paper, which decomposes fault-induced travelling-waves into non-stationary component and stationary component and then get the approximate analytic solution of stationary component. Non-stationary component reflects...
Current travelling wave based single-ended fault location method needs to recognize the travelling waves propagating from the fault direction as well as the travelling wave reflected from the fault point or remote-end bus. This paper firstly compares the current travelling waves of the fault line and the longest health line connected to the local bus based on dyadic wavelet transform to obtain the...
Backup protection is indispensable, particularly as for adjacent devices. Unfortunately, the backup protection has played a negative role during the overload and power swing, and sometimes caused the cascading tripping blackouts. Therefore, it is necessary to re-recognize the role and the scheme of backup protection. This paper presents an integrated backup protection scheme, which separates the backup...
This paper firstly evaluated the impedance method and traveling waves method for fault location, and studied the robustness of fault location method based on impedance. Then it proposed an assembled fault location method for a transmission line based on single-terminal electrical quantities, in which the fault zone was firstly determined by impedance method with robustness then the accurate fault...
