Bird-related fault analysis and prevention measures of ±400 kV Qinghai-Tibet DC transmission line

Birds’ activities may cause short-circuit damages of transmission line (TL), especially in the areas without tall trees and other vegetation. ±400 kV Qaidam-Lhasa DC TL with an average altitude of about 4650 m in China is the highest DC TL in the world. Since November 2011 to the end of January 2017...
