Abstract

This paper analyzes the possibility of utilizing the measurement results made by smartmeters to decrease the number of customers affected by prolonged outages so increasing smart grid reliability. For this scope this paper proposes a continuous monitoring of system impedance so that it would be possible to detect the progressive degradation of some system component and to assert its localization with certain accuracy. The approach is based on theory developed for fault location and theory of synchrophasors. Some experimental results, obtained with the presented approach are reported.
