The investigations on recent blackouts have disclosed that one of the main reasons for
cascaded tripping of protection systems is hidden failures (HFs). This involves an in-depth …

In this paper, a detailed study of the modes of hidden failures (HFs) in protection systems is
carried out, and probabilistic modeling methodology is used for analyzing the impact of HFs …

Major blackouts of electric power systems in which many customers are left without power
are rare events. However, the effects of blackouts, for instance, can be catastrophic. It has …

Protection system plays an important function in maintaining the stability and reliability of the
electric power grid. However, most of the major blackouts happened throughout the world …

Electrical power systems are heavily instrumented with protection assemblies (relays and
breakers) that detect anomalies and arrest failure propagation. However, failures in these …

Large scale blackouts normally go through several sequential phases according to the
propagation speed of branch outages and the disruption level of power grids. It is crucial to …

Studies of major blackouts reveal that power system protection devices have contributed to a
majority of system disturbances. As the most troublesome failure of relay protection, hidden …

Cascading failure is the main mechanism for progressing large blackouts in power systems.
Following an initial event, it is challenging to predict whether there is a potential for starting …

A hidden failure embedded DC model of power transmission systems has been developed
to study the power law distributions observed in North American blackout data. We …

Recent blackouts offer testimonies of the crucial role played by protection relays in a reliable
power system. It is argued that embracing the paradigm shift of adaptive protection is a …
