Aiming at the problem that the hidden trouble of tree barrier seriously threatens the safe operation of power lines, the typical tree species in the corridor of power lines in Guangdong area are investigated and studied. Firstly, a tree height growth prediction model based on Richard’s equation is established. The correlation deviation test results show that the model can accurately predict the tree height. The hidden trouble of tree barrier under line and the hidden trouble caused by wind deviation of wire are analyzed. Finally, the model for predicting the clearance distance from tree to power lines is established. By predicting the clearance distance between wire and tree, the functions of real-time detection of hidden trouble of tree barrier and risk assessment and prediction of tree barrier are realized. It avoids the flashover fault caused by the excessive growth of trees, and ensures the safe and stable operation of power lines.
