Low‐Frequency Oscillation Suppression of FDR Time‐Domain Diagnostic Waveforms for Cable Defects Based on Splicing Technology

High Voltage, EarlyView.
ABSTRACT A time domain pulse (TDP) based on the frequency domain reflectometry (FDR) method can be used to diagnose the insulation state of cable defects. However, because of the limitations of the FDR test instrument, the lack of a reflection coefficient spectrum (RCS) in the low‐frequency band (LFB) can result in low frequency oscillation in the time

Cable Layout Optimization of Offshore Wind Farm Based on Global Dynamic Minimum Spanning Tree Algorithm

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Wind energy has become one of the most promising new energy resources. In the construction of offshore wind farms, the cable accounts for about 10% of the total investment, and the optimization of the cable layout is necessary for reducing the total cost of the wind farm. In this paper, we proposed a novel algorithm for the optimization of the
