Abstract With finite element simulation software COMSOL, this paper calculated background potential of wind turbine blade. Based on critical length criterion, electric field of lightning initial streamer from blade and critical length were studied under different atmospheric conditions, and the critical background potential was analyzed. The mechanism of initial streamer electric field and critical length affecting the upward leader inception from blade was revealed, thereby accordingly the assessment system of lightning upward leader inception from wind turbine blade was proposed. Moreover, the impact of atmospheric conditions on initial streamer electric field and critical length was explored. It is shown that when lightning conditions are constant, the initial streamer electric field and critical length change under different atmospheric conditions, leading to the change of critical background potential, which in turn affects the upward leader inception from blade. The change of atmospheric conditions makes the ionization degree of initial streamer zone different, which affects the initial streamer electric field and critical length. The influence of air pressure and temperature is more obvious, while the effect of humidity is smaller. The conclusions provide a useful reference for the theoretical research on wind turbine lightning protection.
