Lightning Overvoltage and Protection of UHV Grid
Chapter 5 studies lightning protection and its computation and protective measures of UHV transmission lines, substations, and converter stations on the basis of analysis of the formation mechanism of lightning overvoltage. It innovatively puts forward the comprehensive measures of integrated optimization of the ground wire protection angle, design of the ground wire at the line feed segment, and substation lightning arrester configuration, thus significantly reducing lightning lateral strike or counterstrike probability and effectively suppressing the lightning overvoltage amplitudes to ensure the safety of equipment.
