Abstract

The lightning damage seriously affects the normal operation of wind turbines, but there is currently few quantitative analysis methods for the failure risk of the lightning attachment system on wind turbine. Based on leader development model, this paper proposes the definition and calculation method of the lightning shielding failure rate (LSFR) of the lightning attachment system on wind turbine. Taken into the influence of the blade orientation, the LSFR of the blades regarding different lightning attachment systems were comparatively analyzed. The proposed assessment method can provide a theoretical basis for the optimal design and failure risk assessment of the lightning attachment system on wind turbines.
