Device Synchronization for Fault Localization in Electrical Distribution Grids

Abstract

This paper looks at providing an efficient method of synchronizing devices deployed in an electrical grid. The proposed method focuses on device synchronization specifically for localizing faults on distribution networks. It analyses the travelling waves that are present on the electrical grid at and around the time of the fault. It is a synchronization method which uses external signals to synchronize the fault events detected by the devices without reliance on accuracy of clocks used in each device. Initial experimental results shows that this is a promising approach.
