TLDR
In this paper, a fault location method based on voltage change was proposed for the distribution network, which can adapt to different penetrations of distributed generations in all the practical scenarios, and the fault resistance and unbalance of network are considered too.Abstract:
As more and more distributed generations are connected into the distributed network, the traditional fault location methods are not accurate or suitable. A method of fault location for distribution network based on voltage change was proposed. The method has two steps: firstly, calculating the line group on which the fault may occur by the error index obtained from voltage change; secondly finding the accurate fault position using the voltage change and impedance matrix. This method can adapt to different penetrations of distributed generations in all the practical scenarios. The fault resistance and unbalance of network are considered too. IEEE 34 nodes test feeder was tested, and the result approved great and can meet the need of distribution network fault location.read more

TL;DR: In this paper, a fault location method for an active distribution network based on a minimized voltage estimation error is proposed. But the method only needs to collect the power frequency measurement information before and after the fault, and can take into account the influence of unbalance between a distributed power supply and three-phase parameters of the distribution network.
