Design and test of a novel power electronic device for phase sequence exchange technology

open access: yesInternational Journal of Electrical Power & Energy Systems, 2021
With the development of power electronic technology, many conceptual technologies have been applied in practice. Phase sequence exchange (PSE) is a recently developed emergency control technology that can reduce the power angle by 120°, thus preventing the system from losing synchronization.

The impact of phase sequence exchange on relay protection and its resolution schemes

open access: yesIET Power Electronics, 2023
Phase sequence exchange (PSE) is a recently developed emergency control technology that uses power electronic devices to quickly change the original phase sequence connection mode of the transmission line from A‐A', B‐B', and C‐C' to A‐C', B‐A', and C‐B',

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.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
