The DC-side line faults in high-voltage direct-current (HVDC) systems utilising voltage-source converters (VSCs) are a major concern for multi-terminal HVDC systems in which complete isolation of the faulted system is not a viable option. A number of challenges are posed by both pole-to-pole and pole-to-ground faults including the presence of very fast and high amplitude discharge current from ...

Motivated from the quadratic dependence of peak structural displacements to pulse period, $T_p$, pulse-like ground motions, this paper revisits $T_p$--$M_\text{W}$ relations motions generated near-source earthquakes with epicentral distances, $D\leq$ 20 km. A total 1260 are interrogated wavelet analysis identify energetic acceleration pulses (not velocity pulses) and extract their optimal ampli...

In the manufacturing domain, few new distributed systems are built ground-up; most contain wrapped legacy components. While the legacy components themselves are already well-tested, imperfect integration can introduce subtle faults that are outside the prime target area of generic integration and system tests. One might postulate that focused testing for integration faults could improve the yie...

These geohazards have brought about severe damages to buildings, bridges and other facilities. In order to warn of and mitigate disasters, it is urgently necessary to obtain the latest rate, ex...

A new scheme to enhance the solution of the problems associated with Transmission line protection with Statcom connected is presented in this paper. The fault detection is carried out by using energy of the detail coefficients of the phase signals and artificial neutral network algorithm used for fault type classification and fault distance location for all the types of faults for 220 KV transm...
