Fault location, Series compensation, Transmission line.


A new method for locating faults on series compensated high voltage transmission lines, using instantaneous values has been proposed in this paper. Based on the results achieved with the new algorithm, using instantaneous values, the distance to fault location has been estimated very accurately. However, the accuracy of the fault location is limited to the ability to capture data samples before the operation of the MOV. The proposed algorithm incorporates special techniques to avoid the limitation caused by the operation of the MOV. It is formal that although the accuracy of fault location using the algorithm proposed is slightly reduced, but still acceptable. This paper describes the new algorithm and examines its accuracy as compared to other method.
