Studies on Fault Location Algorithms for HV TransmissionLine Using Both Line Terminals Asynchronous Data

Shu Hongchun Gao Feng ( Yunnan Institute of Technology) Chen Xueyun Xu Chengbin ( Harbin Institute of Technology)  
The paper describes new fault location algorithms for ( un ) transposed single - circuit line and for double - circuit line. The propose scheme has following improved aspects: ①The measurements takenat the two ends are not required to be synchronized.②The technique is suitablefor(un) transposition long line . ③The precision of locating fault is virtually independent of the shunt capacitance, fault tran-sient impedance and source impedance,etc. Results of transient performance of locating fault show that the presented technique is feasible.
