An Intelligent Fault Detection Model for Fault Detection in Photovoltaic Systems [PDF]

open access: yesJournal of Sensors, 2020
Effective fault diagnosis in a PV system requires understanding the behavior of the current/voltage (I/V) parameters in different environmental conditions. Especially during the winter season, I/V characters of certain faulty states in a PV system closely resemble that of a normal state.

The Fault Detection Problem [PDF]

open access: yes, 2009
One of the most important challenges in distributed computing is ensuring that services are correct and available despite faults. Recently it has been argued that fault detection can be factored out from computation, and that a generic fault detection service can be a useful abstraction for building distributed systems.
