Redundant ADS and INS High Sensitivity Fault Detection Method

Xibei Gongye Daxue Xuebao, 2020
The fault detection function of GLT method is approximately proportional to the square of fault value, the value of the fault detection function is lower than the detection threshold when the soft fault is small, which leads to the low sensitivity of ...

The Fault Detection Problem [PDF]

, 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.

Estimation of inertia demand in power systems considering wind power virtual inertia

International Journal of Electrical Power & Energy Systems
The high proportion of renewable energy integrated into the grid through numerous power electronic devices has reduced the overall system inertia level and operational stability and caused poor disturbance resistance.
