International journal of hydrogen energy, 2021
A super-high-speed electric air compressor for a hydrogen fuel cell vehicle must have a wide speed range and high-speed regulation response capacity. However, due to the distortion of the air gaps magnetic field of the super-high-speed permanent magnet ...

Residual Flux Measurement of the Single-Phase Transformer Based on Transient Current Method
IEEE transactions on applied superconductivity, 2020When the no-load transformer is connected to the power grid, an inrush current may be resulted as the existed residual flux in the transformer core. To suppress this inrush current, the detail information of the residual flux needs to be known.

Impacts of Current Limiting on the Transient Stability of the Virtual Synchronous Generator
IEEE transactions on power electronics, 2023This article investigates the impacts of different current limiting strategies on the transient stability of the virtual synchronous generator (VSG). The power–angle curve of the VSG under different operating conditions is theoretically characterized in ...

Transient based protection using current transients
2008 IEEE 2nd International Power and Energy Conference, 2008A transient based protection criterion using the wavelet transform results of current transients from the two ends or three ends (T-type line) of high voltage power transmission line is presented. According to the attenuation effects of high voltage transmission line and busbar capacitance to high-frequency current transients, differences of current ...

Transient current estimation using S3C (Standard cell current transient characterization)
2015 19th International Symposium on VLSI Design and Test, 2015This paper continues to build on the dynamic current transient estimation method introduced in previous work. Our previously introduced method uses pre-characterized data from standard cells to estimate the total current transient of a path. This method eliminates the necessity of running resource intensive full-chip SPICE simulations to estimate the ...

Transient Current Waveform Similarity Based Protection for Flexible DC Distribution System
IEEE transactions on industrial electronics (1982. Print), 2019Unlike the traditional system frequency measurement-based protection in ac distribution systems, the protection in dc systems must deal with complex fault transients and identify the faulty section within milliseconds, as power electronic devices can ...

Superconductors Science and Technology, 2019
It is a general belief that no insulation (NI) coil technology is a path to very high field superconducting coils. Recent experience has shown that there are aspects of NI coil design that, if not addressed, can possibly lead to coil failures.
