Lightning strike damage accounts for a significant amount of wind turbines failure. An accurate evaluation of wind turbines' reliability considering lightning strike is thus of critical importance. This research develops two novel lightning stepped leader models considering the stochastic properties and the branching geometry of lightning. In the framework of the reliability analysis of wind turbine blades, the finite element analyses including the two new leader models are conducted and then the electric field in the wind turbine blades are studied. The results show that the branched model adds extra increment of the electric field in the wind turbine blades which is more practical for the wind turbine lightning protection, wind farm siting, and operations and maintenance of wind farms.
