A Review on the Application of the Time Reversal Theory to Wire Network and Power System Diagnosis
Résumé
Transmission lines are the backbone structures of electrical systems. They play a primary role in energy and signal distribution where their reliable functioning is of critical importance. The fault location problem has been thoroughly studied due to the importance of safety and reliability aspects. Among various methods, time reversal (TR), which is an adaptive focusing technique employed to focus waves in space and time, has been lately applied with success to transmission line fault diagnosis. Its unprecedented performance has been demonstrated for precisely locating soft and hard faults in simple and complex topologies in both power and communication networks. This paper provides an overview of the state of the art TR techniques and their applications in communication and power networks.
