Fault Location Method Integrating a Distributed Measurement System and Wavelet Analysis

In the literature, several methods dealing with the problem of fault location in power distribution system can be found. A possible approach is to use a distributed measurement system which analyzes the transient voltage in many network points. The main drawback of such a solution is the large number of measurement stations required. In this paper an approach combining the use of a distributed measurement system and the wavelet-based analysis of the transient voltages is proposed to tackle this issue. Simulation results show the good performance of the proposed technique.
