Description
Summary:Generally, short circuit faults are the most important disturbances in power transmission lines. Accurate and fast finding of fault location, are the main characteristics of a proper fault locating system during transient and stable faults. In this paper, after a short review on current methods and techniques in the field of fault locating in transmission networks, a new method has been introduced using the data obtained from single terminal transient input voltage. The Wavelet Transform is used for identification of the transient wave receiving time in associated terminals. The performance of the proposed method has been tested on a standard network against various fault types, different fault resistances, and for several fault initial angles, using MATLAB simulation tools. The obtained results showed proper accuracy and correctness of the proposed technique.
