Abstract: In recent years,with the continuous extension of the power grid and the improvement of the ecological environment,the activities of birds in the vicinity of overhead power lines have increased,which has had a certain impact on the safe operation of the power grid.This paper analyzes the types and mechanisms of bird damage,as well as the regional distribution and laws.Then typical examples for bird damage identification are provided.The common bird damage prevention measures are studied,and new bird prevention measures are proposed to address the shortcomings,improve the transmission line bird prevention level,and reduce the transmission line trip rate,which is of great significance to ensure stable and reliable power supply for the power system.
