In recent years, in order to meet the huge demand for electricity brought about by economic development, many ultra-high voltage project lines China have been built one after another, alternating vertically and horizontally, gradually forming a large-scale high-voltage trunk line network. transmission world, there is lack of relevant standards operational experience. Lightning strikes as most profound influence on stable operation current line. This paper conducts an in-depth study how protect ±1100kV UHV DC from lightning, combining lightning protection technology geographical factors develop series theoretical analysis verification, hoping provide some reference value national research.
