Under certain critical fault conditions, the fault-induced transient can be quite weak for fault detection to work properly.
Identifying the bearing fault-induced impulsive components in the frequency domain is a key step in the corresponding fault detection.
For fault-induced islanding, protection relays equipped by DG, such as overcurrent relay, are responsible to isolate the DG from the fault [4, 5].
Cochannel-interference-induced outage probability is used as a performance measure.
As told to The Post last month, The American Public Power Association, a group representing municipal electric utilities, says that squirrels are the most frequent cause of power outages in the U.S., although it notes that squirrel-induced outages typically affect fewer people than outages caused by storms.
· More dispatches from the war against squirrel terrorism: in Colorado, squirrel-induced outages affected 41 computers in more than 50 voting stations.
The model estimates hurricane-induced outages prior to landfall with great predictive accuracy, based on only few input variables.
Three types of actuator faults are considered, namely: the loss of effectiveness fault, the outage fault, and the stuck fault.
A more practical model of actuator faults than outage is considered.
Thus, the arbitrarily small sensor stuck faults, including outage faults can be detected in finite-frequency domain.
The problem of adaptive fault-tolerant control for linear systems with time-varying actuator faults including outage and loss of effectiveness is investigated in this paper.
