Feasibility analysis of neutral grounding by small reactor of HVDC converter transformer

open access: yesEnergy Reports, 2022
Nowadays, the scale of power grid is remarkably increasing and there is a continuous reinforcement of AC–DC hybrid systems. Thus, the single-phase grounding fault currents on the AC grid-side of rectifier and inverter stations increase significantly ...

Research on selective leakage protection of 10 kV system based on transient characteristic parameters in coal mine

open access: yesMeikuang Anquan, 2022
When a single-phase grounding fault occurs in the coal mine 10 kV power supply system, due to the low sampling frequency of the system, the traditional transient line selection method is easy to lose the “line selection information”, and is greatly ...
