Abstract

The damage of wind turbine (WT) blade caused by lightning strike is a serious threat to wind farm. Traditional methods cannot calculate the lightning strike probability of any location on the WT blade surface. Besides, there are not any developed theories to instruct the design of WT blade lightning protection system ( LPS A probabilistic risk assessment (PRA) of lightning strike on WT blade was established according to the proposed method of calculating lightning strike probability of any location on WT b lade surface , based on the physical mechanism of upward leader (UL) inception The lightning strike probability distribution of 1.5MW WT was analyzed , including the different positions of WT blade, different lateral distance and different kinds of receptor s . The reliability of the PRA was validated by experimental results. The PRA can be used as the guideline of the design of WT blade LPS.
