Distributed fault detection for interconnected second-order systems with applications to power networks

摘要

Observers for distributed fault detection of interconnectedsecond-order linear time invariant systems is studied.Particularly, networked systems under consensus protocols areconsidered and it is proved that for these systems one canconstruct a bank of so-called unknown input observers, and usetheir output to detect and isolate possible faults in the network.The application of this family of fault detectors to power networksis presented.
