Control Parameter Analysis for an SRM Inverter for Range Extender Units with Integrated DC–DC Converter
Journal of Electrical Engineering & Technology - Tập 18 - Trang 1883-1892 - 2023
Georg Tobias Götz, Jan Kolbe, Anne von Hoegen, Rik W. De Doncker
In modern electrical traction drives, a variable dc-link voltage can be applied to increase efficiency in partial load. A dc-dc converter can supply a variable dc-link voltage and transfer energy between the battery and the dc-link. Hybrid cars combine the advantages of long driving ranges with the partial zero-emission operation. In series-hybrid drive trains, a switched reluctance machine can be...... hiện toàn bộ

Compact Dual-Mode Balun Bandpass Filter with Improved Out-of-Band Performance
Journal of Electrical Engineering & Technology - Tập 16 - Trang 1841-1844 - 2021
Shan Shan Gao, Gang Yu Yi, Sheng Sun
A compact dual-mode balun bandpass filter with improved out-of-band performance is proposed based on a ring resonator. In order to excite the two degenerate modes and obtain filtering balun performance, three parallel-coupled lines are placed at three excitation ports along the ring resonator. By properly arranging the angles between the excitation arms, four transmission zeros can be realized to ...... hiện toàn bộ
Determination of Power Transformer Fault’s Severity Based on Fuzzy Logic Model with GR, Level and DGA Interpretation
Journal of Electrical Engineering & Technology - Tập 19 Số 4 - Trang 2527-2548 - 2024
Sunil Gopakumar, T. Sree Renga Raja
AbstractTransformer defects are defined by their severity which is the intrinsic property of the transformer. Several approaches for identifying the severity of Power Transformer (PT) problems have previously been proposed; however, most published research does not incorporate Gas Level (GL), Gas Rate (GR), and DGA interpretation into a unified strategy. A novel te...... hiện toàn bộ
An SOC-Based Switching Functions Double-Layer Hierarchical Control for Energy Storage Systems in DC Microgrids
Journal of Electrical Engineering & Technology - - 2024
Shu-Ran Wang, Zhan-Shan Wang, Xiao-Lu Ye
In order to improve the control performance of state-of-charge (SOC) balance control and expand the application scenarios of SOC balance control, in this paper, an SOC-based switching functions double-layer hierarchical control is proposed for distributed energy storage systems in DC microgrids. Firstly, the switching functions in the primary layer of double-layer hierarchical control, which is de...... hiện toàn bộ
Improved Hausdorff Distance Based Pilot Protection for Multi-terminal HVDC system
Journal of Electrical Engineering & Technology - Tập 16 - Trang 1955-1969 - 2021
Qing Huai, Liang Qin, Kaipei Liu, Yi Xu, Fangzhou Wang, Hua Ding
In order to overcome the weakness of dc line protection under high impedance fault, a traveling wave similarity based pilot protection method is proposed using improved Hausdorff Distance algorithm. The issue of asynchronous data, noise and anomalies are solved with the improved Hausdorff Distance algorithm. The instantaneous frequency based wave head detection method is used to overcome the probl...... hiện toàn bộ
