Description
Summary:This paper studies the influence of different parameters on the shielding failure of high voltage direct current (HVDC) transmission lines. A numerical of analysis model considering the developing process of the downward lightning leader based on electromagnetic field theory is used to estimate the lateral striking distance to the transmission line. The influences of these factors on the shielding failure of the HVDC transmission line (TL), including different parameters of the downward lightning leader, HVDC transmission line, and weather conditions, have been considered in this analysis. The results show that the dimensions of the transmission line strongly affect the analyzed results of the HVDC-TL shielding failure.
