Abstract It is important to reduce the impact of lightning strikes because lightning can create overvoltage in the grid of the wind turbine and affect power quality. One of the ways to improve the stability of power facilities used in power systems is to use power surge arresters and to protect against transient overvoltage and surges in normal operation. So This paper analyzes the influence of overvoltage caused by lightning when the ground impedance is changed considering the grounding method of the lightning arrester and the corona effect in the wind farm.
