Abstract

This chapter explains application of the electromagnetic time reversal (EMTR) to fault location in power grids. The fault location functionality is an important online process required by power systems operation. In transmission networks, this functionality is needed for the identification of the line experiencing a short circuit and to support the consequent reconfiguration of the network to anticipate severe cascading consequences. In transmission networks, fault location functionality is needed for the identification of the faulty line and the adequate reconfiguration of the network to prevent severe cascading consequences. Single‐terminal measurement‐based fault location methods estimate the fault distance by using voltage and current measurements at a particular end of the line. Multiterminal fault location methods require a global positioning system (GPS) to provide a common time reference. Their performance can also be affected by the accuracy and the loss of the GPS signal.
