Current‐Carrying Characteristics of High‐Voltage Land Cables With Different Grounding Methods for Low‐Frequency AC Transmission

High Voltage, EarlyView.
ABSTRACT Low‐frequency AC transmission holds promise for high‐voltage land cables, but its ampacity is significantly influenced by cable grounding methods and other structural factors. To explore the specific low‐frequency current‐carrying characteristics of high‐voltage land cables, this paper conducts a thorough theoretical analysis of the coupling ...

Study on the Amplification Factor of Ice‐Shedding Jump Height of Transmission Lines Under Ice–Wind Coupling

High Voltage, EarlyView.
ABSTRACT Ice accumulation on transmission lines poses a persistent threat to grid stability, yet precise technical guidance for the dynamic response during ice shedding under wind loads remains insufficient. In response to this issue, this study uses C++ to create a calculation program and obtains aerodynamic coefficients of ice‐covered conductors with
