Abstract
According to the fault statistics of ultra-high voltage (UHV) DC transmission lines in China in recent years,lightning fault is in the first place among all kinds of faults.Lightning damage has become an important factor affecting the safe operation of UHV DC transmission equipment.The ±800 kV UHV DC transmission line from Yibin to Jinhua is an important channel of clean energy transmission in our country,so its safe and stable operation is particularly important.Based on two cases of lightning fault occurring on the Yibin to Jinhua UHV DC transmission line,a comprehensive analysis is made by using lightning location system,fault recording and ranging,field fault inspection and simulation,which indicates that the two lightning faults are both caused by lightning shielding failures.A risk assessment is made on the lightning fault of the Yibin to Jinhua UHV DC transmission line based on the measured data of lightning location system,and some preventive measures are proposed.关键词
