A New Phase Sequence Exchanging Control Method for Reducing Impulse Current and Voltage

open access: yesIEEE Access, 2019
Phase sequence exchanging technology (PSET) is a recently developed emergency control technology for out-of-step power systems. The PSET system does not satisfy the condition of synchronization however, and will produce impulse current and impact torque.

IMPULSE WAVES GENERATED BY LANDSLIDES

open access: yesCoastal Engineering Proceedings, 1970
A study programme has been initiated to investigate the impulse waves generated by landslides originating entirely above the water surface It may be seen that the characteristics of this wave depend mainly on the slide volume and the Froude number of the slide upon impact with the water The resulting wave goes through a transition period For the ...
