When a fault occurs in a system, the main problem to be addressed is to raise an alarm, ideally diagnose what fault has occurred, and then decide how to deal with it. The problem of detecting a fault, finding the source/location and then taking appropriate action is the basis of fault tolerant control. In this chapter, an introduction to fault tolerant control (FTC) and fault detection and isol...

Fault management in distribution systems lacks effective solution because of the unavailability of sufficient measurement data and comprehensive tools for fault analysis. To improve fault management, a systematic approach that takes advantage of distribution-level Smart Grid technologies is proposed. The new approach executes very accurate fault locating first, and then advices system operators...

In this report we present a new fault attack that applies to some implementations of elliptic curve scalar multiplication (ECSM). We consider the fault model with 'precise control of time', 'loose control of fault location' and 'random number of faulty bits'. We show that in this fault model the secret key can be revealed with polynomial time complexity and linear number of faults. In addition,...

Current inversion condition leads to incorrect operation of current based directional relay in power system with series compensated device. Application of the intelligent system for fault direction classification has been suggested in this paper. A new current directional protection scheme based on intelligent classifier is proposed for the series compensated line. The proposed classifier uses ...

In this paper, we employ a variant of the communicating finite state machine (CFSM) model for networks to investigate fault detection and location using passive testing. First, we introduce the concept of passive testing, then we introduce the model with necessary assumptions and justification. Then, the model for the observer process is described and a 3-node case is studied to show how fault ...
