When wind turbine is struck by lightning,a strong lightning current would flow into the ground along the tower tube and generate electromagnetic pulse in the tower.The electromagnetic pulse causes severe electromagnetic interference to electronic devices in the tower tube.In addition,induced over-voltage and over-current could invade electronic equipments in the tower and influence the safe and stable operation of wind turbines.In order to study the lightning electromagnetic environment of the wind turbine tower,the finite element analysis software Ansoft Maxwell is used to establish the tower tube model,and the magnetic field distribution around the tower tube is obtained.Then the corresponding lightning protection design is presented according to the analysis results.The results show that interior lightning electromagnetic environment based on Ansoft Maxwell provides certain theoretical basis for the lightning protection design.
